Product Description
Overview of Commercially Pure Nickel Grades
Nickel 200 (UNS N02200), Nickel 201 (UNS N02201), and Nickel 205 (UNS N02205) are commercially pure wrought nickel grades (minimum 99.0% Nickel). They offer high thermal and electrical conductivity, magnetic/magnetostrictive properties, and resistance to caustic alkalis and reducing acids.
-
Nickel 200: Standard commercially pure grade used up to 315 C (600 F). Above this temperature, graphitization and carbon precipitation cause embrittlement.
-
Nickel 200 "Crowns": High-purity primary nickel cathodes/melt additions produced by electrolytic refining (shaped like domed discs/crowns) used to charge melts or for electroplating.
-
Nickel 201: Low-carbon variant (carbon maximum 0.02%) designed specifically to prevent graphitization at temperatures above 315 C (600 F).
-
Nickel 205: Electronic grade containing trace additions of titanium and magnesium to improve electron emission, magnetostriction, and lead-wire strength in electronic tube and grid applications.
