Zinc-Nickel electroplating is an alloy coating deposited from an acid solution that is used for the protection of steel, cast iron, malleable iron, copper, and brass. 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. The typically thickness varies from 0.0003” to 0.0005”.
Plating Thickness: Ranges from 0.0001 to 0.0012 inches.
Corrosion protection: As a true alloy, Zn-Ni coatings are proven to provide two to three times more corrosion-resistant protection than zinc-only coatings. On the Vickers hardness scale, parts coated with Zn-Ni reach 450, compared to less than 150 for zinc-coated parts.
