CarTech 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 solutions, 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 CarTech 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, (specifically significant length change when magnetized), the nickels have been used in sonic devices such as sonar or for control in ultrasonic welding.

CarTech Nickel 200 alloy meets the requirements of ASTM Specification B-160.

CarTech Nickel 201 alloy is a low carbon modification of CarTech Nickel 200 alloy that has found applications in the electronic industry at temperatures up to 1200°F (649°C). It is preferred to CarTech Nickel 200 alloy above 600°F (315°C), because of its better resistance to "creep."

This alloy has a low annealed hardness and very low work-hardening rate that is desirable for cold forming operations such as deep drawing, spinning, coining, etc. It has been used in corrosion-resistant equipment such as caustic evaporators, in spun anodes, combustion boats and laboratory crucibles, and electronic components where its excellent fabricating characteristics provide some advantage.
