What do Nickel alloys look like? Whilst the alloying elements greatly affect the properties of Nickel alloys, the appearance is generally the same, with a lustrous (shiny) white/gray surface. A good way to identify most Nickel alloys is to check the color and shape of the sparks when ground with a high-speed grinding wheel. Nickel and its alloys produce few, short orange sparks. This is in contrast to Iron alloys that produce lots of log orange sparks.

What types of Nickel alloys are available?

Because Nickel is so prominent as an alloying element, there are hundreds of different Nickel alloy products.

Wrought Nickel

Wrought or pure nickel is often utilized for its excellent corrosion resistance, particularly against caustic substances. It is also used for producing electrical components, often stamped from strip material.

Wrought Nickel Characteristics

Strength and Ductility – Wrought Nickel has relatively low strength compared to some nickel alloys, but good ductility. Weldability is good, with many compatible consumables available commercially. Wrought Nickel has excellent corrosion resistance and is often used for its resistance to caustic corrosion even at high temperatures.

Nickel-Iron Alloys

The principle uses of Nickel-Iron alloys exploit the material’s extremely low coefficient of thermal expansion. This makes it ideal for scientific instruments that rely on accurate dimensional tolerance across a wide temperature range.

Nickel-Iron Characteristics

Nickel-iron alloys are typically very soft and malleable, making them ideal for use as seals in metal-to-glass applications. Another revered characteristic is its magnetic properties, giving rise to its use in transformers, amplifiers and more.

Nickel-Copper Alloys (Inconel)

Nickel Copper alloys offer excellent resistance to alkaline solutions and seawater. Common uses include brine processing equipment or allied applications in the food industry.

Nickel-Copper Characteristics

Inconel is capable of being fabricated and welded to produce strong and durable components. It exhibits no ductile to brittle transition, meaning it retains its strength well into cryogenic temperatures. One of the most commonly used Nickel-copper alloys is Inconel 400, a versatile alloy that is available in all common shapes and sizes such as bar, sheet, section and tube. This material is also readily forged and cast, allowing for extremely complex parts to be manufactured. It finds perfect applications in valve bodies, hydraulic tubing, and firewater systems.

Nickel-Molybdenum Alloys (Hastelloy)

These alloys are primarily used for components that are resistant to ferric and cupric acids. Despite containing 26-30% molybdenum, they are available in many different shapes for fabricating into complex components.

Nickel-Molybdenum Characteristics

One of the most common Nickel-Molybdenum alloys is Hastelloy B-2. It is capable of resisting pure sulphuric and phosphoric acids, whilst being very weldable and easy to fabricate with. Nickel-molybdenum alloys also have a low thermal expansion coefficient and low-temperature performance.

Nickel-Chromium Alloys

With extremely high-temperature resistance, Nickel-chromium alloys are found in aerospace engineering and similar industries, where creep resistance is paramount. They are often work-hardenable, making them more versatile for high-strength applications that also require complex shapes and manufacturing processes.

Nickel-chromium Characteristics

Strength at extremely high temperatures is the main characteristic of Nickel-chromium alloys, with creep resistance being an allied benefit. Whilst weldability is not as high as other materials we’ve discussed, the material can be used to make complex shapes using other processes. Its corrosion and oxidation resistance is excellent and aids its use in aerospace turbine engine applications.

Nickel-Chromium-Iron Alloys

Some alloys previously considered Nickel-chromium-iron, have been reclassified as Stainless steels due to their high Iron content, but there are still alloys such as 825 and G-3 that are NI-Cr-Fe materials. The latter, also containing copper, has many applications concerning flue gas desulfurization systems.

Nickel-Chromium-Iron Characteristics

Good weldability allows this material to be used in the fabrication of complex shapes, pipework and process equipment. Its good resistance to phosphoric and sulphuric acids lends itself to the aforementioned gas desulfurization systems, also known as scrubbers. Its coefficient of expansion is low, and mechanical properties such as strength and relative hardness are high.

Nickel-Chromium-Cobalt Alloys

Adding Cobalt to Ni-Cr alloys significantly aids rupture and creep strength. The Cobalt atoms achieve this by enabling solid-solution strengthening of the material. As it has significantly improved creep resistance, NI-Cr-Co alloys are perfect for high-temperature applications.

Nickel-Chromium-Cobalt Characteristics

Alongside improved strength and creep resistance, alloys such as HR-160 have very high resistance to sulfidizing environments, even at high temperatures. Weldability is good, with many filler materials being commercially available.

Nickel-Chromium-Molybdenum Alloys

Alloy C-276 is the most widely used Ni-Cr-Mo alloy, the main plus point of this material being its excellent resistance to reducing acids such as hydrochloric and sulphuric. Alloy C-276 is commonly used to make pressure vessels, scrubbers and reactor vessels.

Nickel–Chromium-Molybdenum Characteristics

This alloy, like most Nickel-Chromium alloys, has very good high-temperature corrosion resistance, particularly against reducing acids. It has reasonably high strength, and high weldability, allowing it to be fabricated into complex shapes and assemblies.

Conclusion

Nickel is an incredibly useful material in industrial processes. Whilst it is generally too expensive to use for anything outside of its tailored use cases, its properties ranging from high and low-temperature corrosion resistance and strength to high weldability, make it perfect for processing industries involving caustic, acidic or other corrosive substances.

Advantages of Copper Pipes

Ease of Working

Copper is a relatively soft, malleable material. It is easily worked with basic hand tools and is especially easy to create secure joints with brazing techniques. Because of its malleability, Copper can be bent into tight shapes and radii for complex installations. This is in contrast to steel and stainless steel, that generally require more force and complex tooling to bend, thread and join. Whilst welding is a strong and simple method, it comes with more complex requirements and is harder to do in the field.

Thermal Conductivity

Copper is extremely good at conducting heat. In some applications this is a downside, but it allows copper piping to be used for things like heat exchanges, and radiators more effectively.

Advantages of Steel Pipes

Strength

Steel is a much stronger material than copper, this yields many advantages, one of which is that steel pipes can support their own weight for greater lengths. A run of copper pipe may well need twice the amount of support brackets as steel. The material having a higher strength also allows steel and stainless steel pipes to contain much higher pressures. In some applications in excess of 300 bar.

Corrosion resistance

Stainless steel pipes are significantly more corrosion resistant than mild steel, but are even more durable than copper too, as copper does degrade over time. This is mostly due to chemicals in the liquid it contains. Many stainless steels are also resistant to attack from acidic and alkali solutions, allowing them to be used in a wide variety of applications in food, beverage and pharmaceutical applications.

Cost

Steel is considerably cheaper than both copper and stainless steel, and can offer most of the benefits of stainless steel, bar the corrosion resistance. Steel is a strong and cheap piping material that can be easily joined and welded.

In some cases galvanized steel can be used in place of stainless steel as a cost effective solution, but the zinc coating can restrict its application.

Why is copper pipe so expensive?

There are few reasons why copper costs more than the alternatives, such as steel, stainless steel and PVC.
  • Low supply – compared to some metals such as Iron, Copper is relatively sparse on our planet, with only 22 million tons of copper mined in 2022, in contrast to the 2.6 billion tons of iron ore mined in the same year.
  • Difficulty of refining – Whilst copper is not as complex as some materials to refine, such as aluminum, it requires some expensive measures in place to reduce the impact to the environment. We touch upon this more further on.
  • Demand – Copper is not only revered for its piping uses, it is also used extensively for its electrical conductivity. Almost every electrical device uses some amount of copper. With the world ever increasing its production of electrical products, so too is the demand for copper.

Why does Copper turn green?

Whilst Copper does not rust in the same way that Mild Steel does, it does still oxidize with oxygen in the air. The Copper Oxide created has a distinctive green color. Thankfully, unlike steel, the initial oxidation protects the underlying metal from further corrosion.

One of the most well known examples of this phenomenon is the Statue of Liberty, which has developed a vivid green hue since its installation over 100 years ago. For more information on why copper turns green, read our blog all about it.

Is copper corrosion a problem when used for pipes?

Copper is thought to be immune from corrosion, but this is not always the case. Copper can experience high rates of corrosion from relatively low levels of salt and oxidizing acids, the main causes of corrosion in copper piping. The chart below shows the rates of corrosion from Steel, Stainless Steel and Copper samples that have been exposed to a medium composed of water with minute amounts of salt and glucose. It can be seen that copper is actually more susceptible to corrosion in this scenario than Mild Steel, with the corrosion rate per year being over 3 times higher.

What are the environmental impacts of using Copper?

Copper mining can be extremely damaging to certain ecosystems. Like many elements, even metals, a small amount of copper is present in living organisms and is vital to certain functions, including the replenishment of blood vessels and connective tissue. However, the sourcing of this element for industrial refining creates problems in the areas around the copper mines and processing plants. This is due to the leaching of copper-contaminated water into the ground. The drastic increase in the copper concentration in the soil and water systems then affects millions of organisms and habitats, in many cases permanently. Thankfully much of the copper scrap produce can be recycled, reducing the need for copper mining.

When to use Copper and Steel pipes

The properties of steel and copper pipe tend to dictate their use cases, with specific applications making one or the other unsuitable. Some situations include:
  • Use steel, stainless steel or galvanized steel if the pipes need to span gaps unsupported, e.g. across ceiling joists.
  • Use Copper if in a low flow – but confined application – fittings can be soldered to copper to route around complex shapes.
  • Use stainless steel if the fluid contained is at all corrosive, acidic or caustic – check the best type of stainless steel here.
  • Use steel or stainless steel over copper if the pipes will regularly experience freezing temperatures, coppers lower strength makes them more susceptible to bursting

Typical uses of Copper Pipe

  • Heating systems in homes – centralized heating in houses often utilizes copper piping, as it can be made into complex runs to weave around walls, appliances and other objects.
  • Cold water supply – whilst being replaced by plastic (PVC) for the most part, copper piping was commonly used for the cold water supply to homes and businesses, especially inside the property.
  • Refrigerant lines in industrial or domestic HVAC – AC systems will sometimes use Copper piping for refrigerant routing.

Typical uses of Steel Pipe

  • Structural – Alongside fluid carrying, steel pipes are often incorporated in to structural designs in many industries. They can be fabricated to make complex but strong and relatively lightweight components.
  • Compressed Air – Steel pipes are often used to route compressed air systems, as they can contain high pressures without risk of failure, as well as being easy to join and self supporting.
  • Oil and Gas – the oil industry is a huge consumer of steel piping, where it is used to carry both crude and refined product to and from refineries, and then around the world.

Typical uses of Stainless Steel Pipe

  • Process equipment – equipment used in many industries from the pharmaceutical, the food and beverage require hygienic pipework, meaning the systems can be kept clean of debris, corrosion and dirt. Stainless steel is ideal for this due to its high corrosion resistance.
  • Cryogenic – another unique property of stainless steel is that it performs well in extremely low temperatures, this is often utilized in HVAC systems, heat exchanger applications and scientific equipment.
  • Aerospace – thanks to its resistance to corrosion and low temperatures, as well as its high strength, stainless steel and its derivatives are often used in specific low mass aerospace applications.

Conclusion

To the aid of engineers, piping is available in many different materials, and is one of the most widely used sections in industry. From this guide we hope you can now feel content in your selection between copper, mild steel and stainless steel piping, for your project.

We know about the common alloys with carbon to make steel, but what different types of cast Iron are there? We’ll explain all about them in this blog post. What is Iron? Comprising around 35% of the … Continued

The post Wrought vs Cast Iron: What is The Difference? appeared first on Metal Supermarkets.

]]>
What is Iron? Comprising around 35% of the earth’s mass, Iron is an abundant element found on most continents around the globe. To extract, iron ore is mined in large open cast mines, then crushed and processed to refine the ore. From there it can be smelted using large furnaces to melt the iron, once melted the impurities are removed and the iron moved on for further processing.

What is the difference between Wrought and Cast Iron?

Wrought Iron

‘Wrought?comes from the Germanic word ?em>werken?/em> meaning ‘to-work? which is exactly how it’s made. Slabs of iron are hammered, rolled and formed whilst hot, to both create the shape needed and to increase the material’s strength. The material produced is therefore malleable and with a high tensile strength, it can also be reheated and formed making modification and repairs relatively simple.

Chemical properties of Wrought Iron

Containing around 0.1% carbon, 0.25% impurities (sulfur, phosphorus, silicone) and 2% slag, which is a mix of metal and silicone oxides created during the smelting process. Whilst controlled, the chemical composition of wrought iron was generally not as stringently monitored as with modern steel alloys, leading to a slightly more variable material. Ferrous silicate present in wrought iron helps prevent excessive corrosion, meaning wrought iron products left outside form a patina that does not ordinarily require painting.

Physical properties of Wrought Iron

Due to the carbon content and working of the material, which is akin to forging, wrought iron has a very high tensile strength, around 300MPa, which is comparable to modern structural steels.

Cast Iron

Cast iron can be split into two distinct categories: Grey and Ductile, the former being the first and original version, and the latter being an updated, more versatile variant.

Most cast iron has similar properties to wrought, but contains more carbon, around 2-4%. This high carbon content gives it its characteristic properties, hardness. Cast iron is made by smelting iron ore as with wrought, but instead of physical shaping, the molten metal is poured into molds. Iron is not the first material to be cast, but lends itself well to the process, enabling the production of intricately shaped parts that have a reasonably high strength, but with a very low cost.

Chemical properties of Cast Iron

Grey or Cast Iron generally contains around 2-4% carbon, with 1-3% silicone and manganese around 0.5%. Many gray irons also contain around 0.3% Copper. Cast iron is not as resistant to corrosion as wrought iron, meaning it needs some form of coating to prevent rust. The most common type is paint, which bonds chemically to the surface of the part, preventing corrosion.

Physical properties of Cast Iron

The headline features of cast iron are hardness, abrasion resistance and ease of manufacture. Manufacturing, however, generally only pertains to initial production, as welding of cast iron is a difficult task to execute successfully. Its hardness is slightly higher than commercial low-carbon steel, being in line with stainless at around 86 rockwell.

Advantages of Cast and Wrought Iron

As with any material, both cast and wrought iron have their uses, with some applications being suitable for either.

Advantages of Cast Iron

  • Cheaper: Cast iron is a cheap way to make complex parts, with the raw materials being lower than steel or wrought iron
  • Complex shapes: The casting process allows repeatable, complicated shapes to be formed from molds
  • Hardness: Cast iron has a high hardness and abrasion resistance level, making it perfect for using in abrasive environments
  • Vibration damping – due to its molecular structure cast iron has excellent vibration damping effects
  • Heat retention – great heat retention comes from the materials high density

Advantages of Wrought Iron

  • Strength: the manufacturing process and composition make parts made from wrought iron suitable for structural applications such as bridges
  • Re-working: Wrought iron can be heated and reworked, unlike cast iron
  • Corrosion resistance: wrought iron has a natural resistance to rust, meaning for less maintenance issues and cost for finishing

Applications of Cast Iron

Cast iron has hundreds of uses across industry, and is still widely used today:
  • Valve bodies – the ability to form complex shapes makes cast iron great for pipework components
  • Gearbox casings on industrial equipment – the stiffness and vibration damping effect of cast iron is perfect for gear trains.
  • Engine blocks – good machinability alongside heat retention and casting flexibility makes cast iron engine blocks extremely economical
  • Brake rotors – the high strength and low thermal expansion allows for brake rotors that resist warping
  • Cookware – heat retention makes cast iron pans and dishes perfect for baking and frying

Applications of Wrought Iron

Wrought iron has extensive uses but has fallen out of favor to mild steel, common uses that still remain are:
  • Furniture – such as garden tables and chairs
  • Gates and railings – ornamental railings made from wrought iron were very common in 19th and 20th century domestic architecture
  • Balconies – framework and handrailing in cities such as Paris and Rome are traditionally wrought iron

We have put together this guide to allow you to understand more about perforated sheets, including where they are commonly used and how they are made. … Continued

The post What Are The Uses Of Perforated Sheet? appeared first on Metal Supermarkets.

]]>
What is perforated sheet and how is it made? Sheet metal is a thin and flat material used across the industry, found in everything from cars to computers. Perforated sheet is this but with many holes punched in, at regular patterns. Perforated sheet can have a few different shaped holes in it, including squares, rectangles and oblongs, but the most common type is circular holes, usually on a staggered pattern. This is done for ease of manufacture, aesthetics, and strength. Perforated sheets are made by punching holes in regular sheet metal, this is done using either CNC-controlled or mechanically-controlled automated punching machines.

What sheet material can be perforated?

Almost any material that exists as sheet metal can be punched to produce perforated sheets, but the most commonly used are steel and aluminum. Perforated sheets can be bought in a range of thicknesses from 0.019?to 0.250?thick.

Sheet sizes typically follow the standard sheet metal sizes, but at Metal Supermarkets we can cut to any size you require.

What are the uses of using perforated sheets?

Perforated sheets find many uses across many industries, the below is far from an exhaustive list!

Automotive uses for perforated sheet

  • Exhaust baffling – perforated sheet is often used inside mufflers, to both dissipate sound waves and to allow wadding to be contained, without impeding gas flow.
  • Speaker grilles – this is typically made from thin aluminum sheets.

Construction and architectural uses of perforated sheet

  • Facades on buildings – aluminum or painted steel perforated sheet is sometimes used as a feature on the front of modern buildings, providing both an interesting design feature as well as acoustic damping.
  • As aggregate filters – Heavy perforated sheet as part of a filtration system is often used when landscaping on construction sites, allowing grading of bulk materials into particle size.

Perforated sheet used in acoustic applications

  • Acoustic panels – Perforated sheets can be used to dampen, reflect or dissipate sound waves, when installed as part of an acoustic barrier. These are usually placed on walls and ceilings of sound-critical rooms such as recording studios.
  • Acoustic equipment framework – As an integral part of a sound system, perforated sheet can enhance the performance of sound equipment, whilst providing structural support and encasement of the electronic components.

Perforated sheet in bespoke fabrications

  • Cooling and ventilation – Panels on electrical equipment are often made from perforated sheet, to allow closing off from people and objects but also allow good airflow for cooling.
  • Store displays – another use that makes the holes in the sheet a feature, some shop display designers have used perforated sheets to break up the design of a store display.

Filtration in the water & waste management industry

  • Filters and screens – the small holes in a perforated sheet and their range availability are ideal for making filters and screens. They can allow water and small particles to pass through whilst stopping larger debris.
  • Staged filtration – as the hole size and frequency are customizable, a perforated sheet can be used to produce stages of filtration, blocking smaller and smaller particles as the fluid passes through the system.

What are the benefits of using perforated sheets?

Cost

Mesh screens can be made using laser cutting, whilst this process allows more customization, it can be prohibitively expensive. A perforated sheet is an extremely economical way to allow filtration, air flow, or any of the other uses mentioned above, in an off-the-shelf package.

Workability

If bespoke shapes and sizes are needed, perforated sheets can still be processed by laser, guillotine, and press brake as regular sheet metal is. To read more about these processing methods, we have a great guide here.

A wide range of sizes for all applications

The selection of thicknesses and material options allow its use in both light and heavy-duty applications, from painted architectural or design features to corrosion-resistant filtration devices. With the smallest available hole size being 0.063?and the largest being 2.0? there is sure to be a type of perforated sheet to suit your needs!

At Metals Supermarket we carry both mild steel and aluminum perforated sheets, in a wide variety of thicknesses. Check them all out or find your nearest store here.

Aluminum is one of the most commonly used metals by weight in the world’s construction and allied engineering industries, second only to steel. It is an extremely versatile material that has some excellent properties concerning strength and durability.

Why use Aluminum tubing?

Thanks to its great strength-to-weight ratio, ductility, and malleability, aluminum can be made into many different shapes, via both traditional rolling processes as well as extruding. This means aluminum tubing can be made for both precision and cost-effectiveness. When compared to steel, aluminum has two further distinct advantages, strength and corrosion resistance. Whilst steel is stronger per volume, e.g. a bar of steel would be stronger than an identically shaped bar of aluminum, steel has a much lower strength-to-weight ratio. In real-world terms, if two structures were designed to carry the same load, but one made from aluminum and one from steel, the aluminum one would be larger in size but weigh less than half of the steel one.

How is Aluminum tubing made?

Aluminum is derived from an ore called Alumina, which consists mainly of Aluminum Oxide and some trace contaminants. The smelting process is completed using electric arc furnaces, allowing the oxides to rise to the surface. The pure aluminum is tapped off from the bottom.

Once purified, processes are used to introduce new alloying elements, creating many variations, in grade and temper, depending on the requirement. From here the material is cast into ingots or slugs.

The slugs are transported to the extruding plant, where the material is processed into tubes. The extruding process comprises of:
  • Selecting and loading the correct tube die – this depends on the size and shape required, the dies are oiled and in some cases water-cooled
  • The aluminum slug is preheated – this aids the extrusion process and reduces surface imperfections, damage to the dies, and makes complex shapes easier
  • The heated slug is loaded into the extrusion chamber
  • Hydraulic rams force the slug into the extrusion die – anything from 100 to 1,500 tons of force is used, depending on the material and shape
  • The shaped aluminum is cut to length and allowed to cool to room temperature

Typical Uses of Aluminum Tube

Aluminum’s strength-to-weight ratio makes it great for any industry where lightness is a key factor, such as:
  • Aerospace – almost all commercial airplanes use aluminum for structural components
  • Motorsport – aluminum finds uses in all sorts of bracketry, tanks and heat shielding
  • Rigging – Aluminum towers and structures are commonly used in lighting and rigging to create lightweight, easy-to-carry assemblies

Typical Uses of Aluminum Pipe

Aluminum pipe is generally not as prevalent as steel or stainless steel pipe, but there are a few typical use cases:
  • Air Conditioning – from car AC to industrial units, aluminum pipe is often used due to its lightweight, thermal conductivity and corrosion resistance
  • Process pipework – in settings that use nitrogen or helium, aluminum pipe is often used to handle low – medium pressure systems

The difference between Pipe and Tube

In general, pipe is used to carry liquids and gasses, and tube is used to construct frames and other fabricated components. One other distinction is that Pipe is measured by its inside or a “nominal?diameter and a pressure rating, and tube is determined by its outer diameter and wall thickness. These two points are further consequences of being used to carry liquids and gasses. Furthermore, pipe is only round, aluminum tubes can be round, oval, square, rectangular and many other shapes. This is yet another benefit to aluminum; its high ductility allows for complex shapes to be manufactured.

Benefits of Aluminum Tubing

Alternatives to aluminum generally include steel, stainless steel and titanium, aluminum has benefits over all three of these, when in the right conditions.
  • Lighter: Aluminum is lighter than steel, stainless steel and titanium
  • Stronger: Aluminum has a higher strength-to-weight ratio than steel and stainless steel, perfect for lightweight high-stress applications
  • Corrosion resistant: Whilst steel is cheaper than aluminum, any product that sees outdoor use will need secondary finishing by way of painting or galvanizing, Aluminum is corrosion resistant in most applications.
  • Cheaper: Aluminum is considerably cheaper than titanium, another lightweight corrosion-resistant alloy

Types and Grades of Aluminum Pipe and Tube

Aluminum Grades

The two most commonly used grades for aluminum pipe are:
  • Aluminum 6061 – A high-strength alloy, commonly used for walkways, platforms, cover plates, and truck runways
  • Aluminum 6063 – Whilst not as strong as 6061, 6063 is better suited for complex extrusions, meaning it is ideal for air cylinders (thin-walled), furniture and frames

Aluminum Shapes

Thanks to its high malleability, Aluminum can be processed into many different shapes, with more shapes possible when compared to steel or stainless steel
  • Round Pipe – used for carrying fluids and gasses
  • Round tube – used for framework in commercial or cosmetic applications
  • Rectangular tube – often used for lightweight industrial frameworks and bracketry
  • Square tube – also used for industrial frames, as well as motorsports chassis and bracketry
  • Oval tube – commonly used in architectural applications

How Rare is It?

Tin is a relatively scarce element, with a low abundance in the earth’s crust. For context there is approximately 45x more Zinc in the Earth’s crust than tin, and 25,000x more Iron.

Tin mines are often open cast and require large amounts of excavation to extract. For many years a large amount of the Tin supply worldwide came from Cornwall, England.

Where is Tin Found?

As mentioned, most of the global tin ore is mined in Southeast Asia, with Indonesia and China being the biggest contributors. Second to Asia, Mexico and a few other South American countries still mine Tin.

What is the Tin Belt?

Not a fashion accessory, but a wide region of the world where large amounts of Tin are mined to this day. It stretches for approximately 2,800km south from Thailand.

Various other countries fall into the Tin belt region, including Myanmar, Indonesia, China and Malaysia. Around 55% of the world’s tin supply comes from these countries, amounting to nearly 10 million tons.

How is Tin Extracted and Manufactured?

Historically Tin mines were deep conventional mines used to tap into vein deposits of Tin ore, predominantly found in the UK and South America. The mines producing most of the worlds Tin supply in modern times, are Alluvial, meaning they originate from ancient riverbeds or valleys.

These mines are worked by various surface-mining methods. Gravel pumping contributes a large proportion of the world’s mining of Tin. This involves large pumping systems capable of moving both liquid and solids, that are used to sieve the gravel for sand deposits of Tin ore. After separation these deposits are then filtered further by a process of weirs and overflow filters, allowing the lighter soil and debris to float away, with the heavier Tin ore being collected for refining.

How is Tin Refined?

Tin is a relatively simple metal to refine, Firstly, to reduce sulfur, the ore is roasted at around 650 degrees C, leaching with water and acid helps clean the impurities further. Many different types of furnaces are used to refine Tin, with electric or blast furnaces being less predominant compared to Reverberatory furnaces. These heat the ore to around 1400 degrees C, where the tin oxide ore transforms to Tin and Carbon Dioxide. A slag pool will form on top, containing further impurities. Once removed, this is often re-refined to remove the smaller amounts of Tin present. To refine into nearly pure (99.85%) Tin, Fire refining is usually used. The tin from the previous processes is heated in large vessels, with agitation through compressed air. This action causes the minor impurities to oxidize and rise to the surface.

How is It Used?

As one of the oldest metals used by man, Tin has been found used as all manner of practical and cosmetic items by civilizations dating back thousands of years.

One of the most common uses for tin was to combine it with Copper, creating Bronze. Bronze was a pivotal material in human development, with it being used for everything from weapons and armor to tools and drinking vessels.

In modern times, Tin is still used as an alloying element or for plating other materials. One of the most prevalent instances is the plating of cans, for food and beverage containment.

Whilst it is used less and less now, in favor of Aluminum, Tin coating affords excellent corrosion resistance,

Another common use of tin is in solder, it is an effective electrical joining material due to its good electrical conductivity and low melting point.

What are the Grades Available?

Unlike other metals such as steel and aluminum, Tin is generally used in a relatively pure form. The grading schemes are designated by letter, with A as the highest purity at nearly 99.99& pure Tin. Grade B is around 99.8% and so on.

Like most metals, some grades are only available in specific forms, such as powders for sintering, sheet for contact manufacturing and more.

What actually is Nitinol?

The name Nitinol is derived from both its composition and where it was discovered: Nickel, Titanium, Naval Ordnance Laboratory. The NOL was a US military center for research and development, which in 1959 accidentally invented Nitinol.

Originally formulated solely to be a corrosion-resistant alloy, Nitinol was discovered to have some extraordinary properties that soon overshadowed, but in most applications complemented, its impressive corrosion resistance.

Why is it so Expensive?

Although invented in 1959 it took many years for Nitinol to be commercially available. Part of the reason for this is the high level of control needed to create the alloy. Vacuum Arc Remelting is utilized to combine Titanium and Nickel, a process with high operating costs. Furthermore, as with many alloys, the composition is critical to the functionality of nitinol, a change of just 1% in the ratio of Ni to Ti can affect the transition temperature – and thus the usability of the product – by up to 100 degrees Celsius. These factors combined with the relatively high cost of the raw materials needed; namely Titanium, explain why Nitinol is so expensive per unit weight.

The Superelasticity of Nitinol

Nitinol can be bent and formed into complex shapes way beyond the plastic deformation point of most metals, acting almost like a flexible wire. This has enabled its use in a variety of applications. Nitinol can be up to 30x times farther than ordinary metals, and still return to its original shape.

Shape Memory of Nitinol

Perhaps even more extraordinary is the ability for Nitinol to remember its shape. If a piece of Nitinol wire is formed into a shape at a certain temperature, often around 500 degrees C, it will return to that shape when reheated to its transition temperature, which is often as low as 40 degrees. It does this due to the atomic bond between the rows of atoms trying to revert to it’s shape when hot. The change from hot to room temperature happens as the material passes from an Austenitic phase to a martensitic one.

What is the use of Nitinol?

A material like no other, nitinol has some creative and unique uses. Whilst its corrosion resistance and high strength make it a great material for medical applications, the really amazing application utilizes its memory function.

Nitinol in medicine: Stents and braces

A stent is a device that holds open a vein or artery, this is often needed when a patient is suffering from a condition such as Peripheral Arterial Disease. A nitinol stent resembles a cylinder, with the wire being formed into a lattice, similar to the reinforcing seen on a garden hose. The surgeon selects a stent with its outer diameter -in its natural state- slightly larger than the diameter of the artery affected. The stent is compressed to around half of its final diameter, allowing it to be passed easily into the artery or vein. Once in place, the warmth of the human body causes the nitinol to remember its original shape, applying outward pressure on the wall of the vein, preventing it from collapsing. Braces are used in dentistry to adjust the position of teeth over a period of months or years. As these devices need to be strong, corrosive resistance and extremely malleable, Nitinol is used to form the basic structure of many braces and retainers.

Practical uses for Nitinol’s memory affect

There are quite a few devices and trinkets that make use of the memory effect of Nitinol, such as acting as a motor in warm water or as novelty toys. But there are a few applications of this phenomenon that are extremely useful. Because almost all metals heat up when an electric current is passed through them, a piece of Nitinol can be used as an actuator, exerting a force on a system, simply through an electrical circuit being made. This is perfect for situations where electrical motors, or hydraulic systems would be too bulky and impractical.
