Nickel 200 is the most widely used standard grades of commercially available pure brought Nickel along with and Nickel 201. These alloys offer good thermal conductivity, mechanical properties, resistance against many corrosive environments, in particular against caustic alkalis, low electrical resistivity, and good magnetostrictive properties.
Nickel 200 is easily workable by forming and drawing. Nickel 201 is a low carbon variation of Ni200 and has a very low work hardening rate which allows it to be easily cold formed. It also offers better creep resistance and is preferred over Ni200 for applications that experience temperatures over 600°F (315°C).
