Carpenter Nickel 200 alloy is a commercially pure nickel that exhibits good corrosion resistance. It is ferromagnetic and has relatively low electrical resistivity. This combination of properties has allowed its use in a wide variety of applications.

Because the alloy displays good corrosion resistance, it has been used in food handling equipment, caustic solution, and general corrosion-resistant parts and structures. The magnetic and mechanical properties have enabled it to be used in devices requiring magnetic actuated parts. The excellent combination of properties enables Carpenter Nickel 200 alloy to be cold worked by forming and drawing. It is readily welded and will retain its properties at both subzero and elevated temperatures. Its low electrical resistivity has allowed its use as conducting leads and terminals in electrical and electronic components.

Because of its magnetostrictive properties(specially significant length change when magnetized), the nickels have been used in sonic devices such as sonar or for controls in ultrasonic welding.

Carpenter Nickel 200 alloys meets the requirements of ASTM Specification B-160.
