Sulfamate Nickel plating produces a nickel deposit with exceptionally low tensile stress. The purity, corrosion protection, dimensional buildup and resistance to high temperatures of the nickel deposit make Sulfamate Nickel an ideal plating application for engineering components. The low stress of sulfamate nickel plating yields nickel deposits with ductility, elongation and machinability far superior to other nickel deposits.

Sulfamate Nickel excels where a highly ductile, low-stress nickel deposit is preferred, such as for flexing or crimping applications, as well as joining functions such as soldering, brazing, epoxy bonding or welding. Keystone Corporation currently services a wide range of industries in sulfamate nickel plating, including the interconnect, telecommunications, power transmission, medical and defense markets. Sulfamate nickel plating also serves as an excellent underplate for tin plating, silver plating and gold plating and is often used in over-molding and epoxy bonding applications.
