Carpenter Nickel 201 alloy is a low carbon modification of Carpenter Nickel 200 alloy that has found applications in the electronic industry at temperatures up to 1200°F(649°C). It is preferred to Carpenter 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.
