Nickel 200 is a commercially pure nickel alloy
possessing good corrosion resistance and relatively
low electrical resistivity. Has been used in a wide
variety of applications including food handling
equipment, magnetically actuated parts, sonar
devices, and electrical and electronic leads.
Nickel 201 is a low carbon variety of Nickel alloy 200 possessing low annealed
hardness and a very low work-hardening rate desirable for cold forming
operations. It is highly resistant to corrosion by neutral and alkaline salt
solutions, fluorine and chlorine. Has been used in
food and synthetic fiber processing, heat exchangers, chemical and electrical
industries.
