Zinc-Nickel Plating

REPLACEMENT FOR CADMIUM PLATING…ROHS COMPLIANT…EXCELLENT CORROSION RESISTANCE

Zinc-Nickel Plated Bushings

Electrolurgy’s Plated Zinc-Nickel is a durable, highly corrosion resistant coating that was developed in part as a replacement for Cadmium Plating. It is used in the protection of steel, cast iron, copper, brass and bronze. 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.

Electrolurgy also offers RoHS compliant clear and yellow post-plate treatments for increased corrosion protection, specific torque-tension requirements, or color identification.
