Nickel Grades

Nickel alloys are used extensively because of their corrosion resistance, high temperature strength and their special magnetic and thermal expansion properties. Nickel is a versatile element and will alloy with most metals. Nickel  increases the hardenability of the materiel.

Applications of Nickel Alloys

Nickel and nickel alloys are used for a wide variety of applications, the majority of which involve corrosion resistance and/or heat resistance. Some of these include:

  • 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

Advantages of Nickel Alloys

  • Heat-Resistance:  Nickel-base 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.
  • Corrosion Resistance: Nickel-base alloys offer excellent corrosion resistance to a wide range of corrosive media. However, as with all types of corrosion, many factors influence the rate of attack. The corrosive media itself is the most important factor governing corrosion of a particular metal.
  • Low-Expansion:  Nickel was found to have a profound effect on the thermal expansion of iron. Alloys can be designed to have a very low thermal expansion or display uniform and predictable expansion over certain temperature ranges.
  • Electrical Resistance:. 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).
