Plating

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. Accurate Edge offers RoHS compliant clear, yellow and black post plate treatments for enhanced corrosion protection, specific torque-tension requirements, or color identification.

Zinc-Nickel plating is an efficient, economical coating, with minimal environmental impact.
