NICKEL 201, PURE NICKEL, Alloy 201

UNS N02201, EN 2.4068, Ni99.2

Nickel 201 is an unalloyed nickel with Minimum 99% nickel concentration. It has low carbon content as compared to Nickel 200.
Being commercially pure nickel with low alloy elements, it has an excellent resistance in highly corrosive environments like caustic soda, chlorine gas manufacturing process. In comparison with nickel alloys, commercially pure nickel has more electrical and thermal conductivity.
