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