Nickel Institute > Nickel Sulphamate Solutions
By Dr. S. Alec Watson, Dec 1990. Nickel-plating solutions based upon nickel sulphamate are used mainly for electroforming purposes because the internal stress in the nickel deposits is lower than in deposits from Watts-type solutions. Also, higher deposition rates can be achieved. Some engineering nickel plating is done in sulphamate solutions and they have been used for decorative plating. These applications, however, usually use Watts-type formations which, for the same nickel content, are about half the price of the sulphamate solutions.
