Nickel 200/201
(UNS N02200 & N02201/W.Nr. 2.4060/2.4066 & 2.4061/2.4068)

Alloy 200 (UNS designation N02200) and Alloy 201 (UNS designation N02201) are wrought commercially pure nickel. The alloys differ only in the maximum carbon level allowed by specification, 0.15 % maximum for Alloy 200 and 0.02 % maximum for Alloy 201. Both alloys provide highly ductile mechanical properties over a wide temperature range. Both alloys provide corrosion resistance in neutral to moderately reducing environments. In the annealed condition, either alloy possesses the approximate strength of mild steel. As-rolled material is sometimes furnished to provide higher strength levels.
Alloy 200 and Alloy 201 provide high thermal and electrical conductivity in comparison to nickel base alloys, stainless steels and low alloy steels. The alloys are ferromagnetic.
