- Corrosion resistance
- Wear resistance
- Strength at elevated temperatures
Nickel & Nickel Alloys
Nickel and nickel alloys are among the toughest structural materials known. Nickel and nickel alloys are non-ferrous metals with high strength and toughness, excellent corrosion resistance, and superior elevated temperature properties. Commercially pure nickel has good electrical, magnetic, and magnetostrictive properties.
Magnetostriction is a property of ferromagnetic materials that causes them to change their shape when subjected to a magnetic field. The effect was first identified in 1842 by James Joule when observing a sample of nickel. – (extracted from Wikipedia)
Nickel products differ in terms of composition, grade, shape, dimensions, and features. Please review Aerodyne Alloys Nickel Product Specification for more information. Other unlisted, specialty high temperature nickel and nickel alloys are also available, please Aerodyne Alloys for more information.
- Alloy 718 (aka Inconel ® 718)
- Akkit 625 (aka Inconel ® 625)
- Nickel 600
Commercially pure nickel (unalloyed nickel) does not contain or contains only very small amounts of alloying elements.
Nickel alloys contain significant amounts of added elements or constituents.
Clad or bimetal stock consists of two different alloys that are bonded integrally together.
Metal matrix composites have a composite or reinforced metal or alloy matrix filled with a second component, which may be in particulate, chopped fiber, continuous filament, or fabric form.
Nickel Stock Shapes & Forms
Specialty nickel and nickel alloys are available in many stock shapes and forms including near net shapes. Semi-finished stock shapes are suitable for part fabrication by machining, assembly, or other processes. They are also used as feedstock for casting, forging, and spinning.
Common stock shapes and forms for nickel and nickel alloys include bars, rods, tubes, plates, profiles, sheets, strips, shims, spheres, foil, wire, billets, slabs, and blooms. Materials are also supplied as billets, ingots, powders, fillers, and reinforcements. Round, hexagonal, coil, and hollow stock are also available. There are two basic types of anodes.
Plating anodes are in used in plating or electroplating processes. Sacrificial anodes are used to protect stainless steel or other metal structures from corrosion.
Nickel &t’s Uses www.nickelinstitute.org/index.cfm/ci_id/13/la_id/1.htm
Nickel alloys are vitally important to several industries such as aerospace, power generation, and petrochemical. Nickel alloys comprise some of the most valued among specialty high temperature alloys in these markets. The use of high temperature specialty alloys such as Nickel Alloy, Inconel ® 718, Inconel ® 625 and Nickel 600 are key to successful manufacturing in key industries around the world. Structural applications that require specific corrosion resistance or elevated temperature strength receive the necessary properties from nickel and its alloys.
Nickel and nickel alloys are used in a wide variety of applications, the majority of which involve corrosion resistance and/or heat resistance such as:
- Aerospace aircraft gas turbines
- Steam turbine power plants
- Medical applications
- Nuclear power systems
- Chemical and petrochemical industries
A number of other applications for nickel alloys involve the unique physical properties of special-purpose nickel-base or high-nickel alloys. These include:
- Low-expansion alloys
- Electrical resistance alloys
- Soft magnetic alloys
- Shape memory alloys
Nickel-based alloys are used in many applications where they are subjected to harsh environments at high temperatures. Nickel-chromium alloys or alloys that contain more than about 15% Cr are used to provide both oxidation and carburization resistance at temperatures exceeding 760°C.
Nickel, Inconel ® 718, Inconel ® 625 and Nickel 600 offer superior corrosion resistance to a wide range of corrosion effects. Nickel was found to have a profound effect on the thermal expansion of iron. Specialty alloys can be designed to have a very low thermal expansion or display uniform and predictable expansion over certain temperature ranges. The addition of cobalt to the nickel-iron matrix produces alloys with a low coefficient of expansion, a constant modulus of elasticity, and high strength.
Several alloy systems based on nickel or containing high nickel contents are used in instruments and control equipment to measure and regulate electrical characteristics (resistance alloys) or are used in furnaces and appliances to generate heat (heating alloys).
