What is nickel and where is it found?

Nickel is a crystalline metal that is commonly found in the earth’s crust, particularly in areas with high sulphide and laterite-type ore deposits.

The major producers of nickel are Canada, Australia, Indonesia, South Africa and Russia.

Nickel pairs well with other metals to enhance their properties and create incredibly versatile alloys.

What are Nickel Alloys?

Nickel alloys are manufactured from various carefully balanced combinations and ratios of metals that have nickel as one of their primary elements. 

Nickel is primarily alloyed with chromium, copper, iron, aluminium, cobalt, titanium, carbon and molybdenum in varying percentages to enhance the particular qualities required for specific applications, usually in extreme working environments.

 

How were nickel alloys developed?

From the earliest historical records, it appears that a nickel alloy called “white copper” was first used in China in 200 BC.

Modern nickel alloys date back to the work of German scientist Axel Cronstedt in 1751 who combined nickel with copper and zinc, known today as German Silver. His work was further developed by James Riley in 1913 and later by Dr. W.H. Hatfield to create stainless steel by combining nickel, iron, and chromium.

Metallurgical research has led to a wide variety of very advanced nickel alloys, serving the needs of a large variety of industries and applications.

How Are Nickel Alloys Made?

 Carefully selected metals are melted together and purified in an arc furnace in exact ratios, according to the metallic properties desired. 

The nickel alloy is formed into a wide range of shapes and products for various applications using either cold or hot working techniques. 

Why do we use nickel alloy?

The various nickel alloy metals are incredibly versatile and have extraordinary properties such as corrosion resistance and high strength and can be used under extreme temperatures, often making them the only viable option in critical applications.

Compared to austenitic and many other alloys, nickel alloys have specific properties required in various applications and outperform almost all other metals in terms of strength-to-weight ratio, resistance to high temperatures, corrosion, and electrical conductivity in extreme environments.

Which industries use nickel alloys?

Nickel alloys in various forms are indispensable for nuclear and aerospace components, chemical processing, production and transportation equipment in the oil and petroleum industries, surgical implants, medical equipment, marine equipment, automotive parts, valves and pumps, turbine engines, transformers, inductors, magnetic shields, data storage devices, engineering, and in the construction industry.

Typical industrial applications can include tubes, tanks, pipes, mixing devices, pumps, pressure vessels, heat exchangers, furnaces, propellers, offshore pipelines, valves, transformers, memory storage devices, hermetic seals in X-ray tubes, and temperature switches. 

In addition to their industrial use, nickel alloys have a wide range of domestic and consumer applications. This will include towel rails, ornamentation, plumbing and sewerage, coins, jewellery, kitchenware, electronic devices and even guitar strings.

What are the special characteristics of nickel alloys?

  1. Exceedingly high corrosion resistance:

Nickel alloys have exceptional resistance to corrosion and oxidation, making them ideal for use in harsh environments where other materials would quickly degrade, ranging from domestic use to nuclear, gas, oil, and petroleum applications.

  1. Outstanding strength:

Nickel alloys have enormous compressive, yield, and tensile strength in relation to their weight. This makes them highly durable and tough enough to bear vast amounts of weight and stress and to withstand tension and pressure.

  1. Exceptional temperature resistance:

Nickel alloys retain their strength and shape under extreme temperatures, ranging from cryogenic temperatures to environments as high as 980 °C.

  1. Superb ductility:

Nickel alloys are highly ductile, meaning they can be stretched and drawn to a very high degree and withstand very high impact without deforming or breaking.

  1. Great magnetic properties:

Especially those alloys with very high levels of nickel have excellent soft magnetic properties, which means they can be easily magnetised and demagnetised.

  1. Weldability:

Although it requires special skill to weld nickel alloys, they can be welded using manual metal arc, MIG (metal inert gas) or TIG (tungsten inert gas) processes.

  1. Low thermal conductivity:

In very high-temperature applications, nickel alloys limit the heat transfer to other components.

  1. Wide-ranging electrical conductivity according to alloy composition:

Nickel alloys with both higher and lower electrical conductivity are manufactured according to the applications for which they are required. Generally, they have lower conductivity than pure copper, but linked to their strength and corrosion resistance, can serve satisfactorily as specialised electrical conductors.

  1. Low thermal expansion coefficient:

Nickel alloys maintain their dimensional stability over a vast range of temperatures and typically have low thermal expansion coefficients.

This makes them ideal for precision applications that must maintain dimensional stability over a range of temperatures and pressures. 

What are the Main Types of Nickel Alloys?

Wrought Nickel

Used in environments where alkaline chemical resistance and electromagnetic shielding are required.

Nickel-Iron Alloys

Used in environments where low thermal expansion or soft magnetic properties are required, such as precision instruments, seals, thermostats, transformers, inductors, and memory storage devices.

Nickel-Copper Alloys

Used in marine environments where resistance to saltwater is required.

Nickel-Molybdenum Alloys

Used where high acidic chemical resistance is needed, such as in high-quality pumps, valves, gaskets, pressure vessels, heat exchangers and piping products.

Nickel-Chromium Alloys

Used where high resistance to scaling, electrical resistance, and high melting points are required, such as in nuclear reactors, heaters, ovens, and toasters.

Nickel-Chromium-Cobalt Alloys

Typical applications for these alloys include industrial furnace components, gas turbines, and catalyst grid supports to produce nitric acid and fossil fuel.

Nickel-Chromium-Iron Alloys

Used where high stress-rupture, endurance under permanent loads, and high acid resistance are needed, such as in prestressed or reinforced structures, petrochemical furnaces, and sheathing for heating elements.

Nickel-Chromium-Molybdenum Alloys

Offering the best acid-corrosion resistance, nickel-chromium-molybdenum alloys are used in pollution control stack liners, ducts, and scrubbers, as well as in chemical processing components such as heat exchangers, evaporators, or reaction vessels.

Nickel-Titanium Alloys

Used where excellent corrosion resistance, good mechanical strength and shape memory are required, such as medical devices, surgical applications, specialised connectors, spectacle frames, and shock absorbers that provide earthquake resistance in historic stone buildings.

Super Alloys

By adding metals like titanium and cobalt, super alloys are created with exceptional mechanical strength, strength-to-weight ratio, resistance to thermal creep deformation, surface stability, resistance to corrosion and oxidation, and the ability to operate at temperatures very close to their melting points.
