What is Sulfamate Nickel?

Sulfamate nickel is an extremely useful plating that possesses many beneficial properties. Deposited electrolitically, sulfamate nickel is a uniform dense coating of pure nickel. It provides excellent corrosion resistance, high ductility and strength, and good thermal and electrical conductivity. It can be plated on a wide variety of substrates including chilled irons, various steel alloys, stainless steels, aluminum alloys, copper and brass.

Combined with a thin overlay of chromium, sulfamate nickel is the most effective electroplated coating identified for preserving metal finishes for extended periods of exposure to corrosive environments.

Sulfamate nickel is used in engineering applications as a low cost, machineable build-up coating for size restoration resurfacing of defective parts or shells. It is also used as a sealer coating in the Chemical and Food processing industries to prevent iron or other metal contamination.
