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 (Fe64Ni36, INVAR).
- Electrical resistance alloys; Cu-Ni alloys containing 2 to 45{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} Ni, Ni-Cr-Al alloys containing 35 to 95{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} Ni, Ni-Cr-Fe alloys containing 35 to 60{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} Ni, Ni-Cr-Si alloys containing 70 to 80{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} Ni
- Soft magnetic alloys; the high-nickel alloys (about 79{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} Ni with 4 to 5{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} Mo; balance Fe) have high initial permeability and low saturation induction.
- Shape memory alloys; Nickel-titanium alloys (Ni50Ti50) are one of the few commercially important shape memory alloys.
