Nickel 201
Nickel 201 is a wrought commercially pure nickel that provides high thermal and electrical conductivity in comparison to nickel-base alloys, stainless, and low alloy steels. This material is ferromagnetic and responds readily to commercial fabrication practices. Nickel 201 is primarily used in reducing or neutral atmospheres but may also be used in oxidizing environments.
