Zinc Nickel Plating

Zinc-Nickel electroplating is an acid coating that is used in the protection of steel, cast iron, malleable iron, copper, and brass. Zinc-Nickel is recognized as an environmentally safe alternative to cadmium electroplating. In specific applications, Zinc-Nickel demonstrates equivalent, or better, corrosion properties when compared to cadmium. Zinc-Nickel is normally applied for corrosion protection purposes, and functions as a “sacrificial coating”, corroding before the base material. Zinc-Nickel can also replace cadmium in galvanic interaction applications where the coating is intended to minimize corrosion caused by the interaction of dissimilar metals. Chem Processing Inc.
