This plating is a combination of a High Nickel Zinc-Nickel alloy (10% – 15% nickel) and some variation of chromate. The most common mixed chromates include Hexavalent Iridescent, Trivalent, or Black Trivalent Chromate. Used to protect steel, cast iron, brass, copper, and other materials, this acidic plating is an environmentally safe option. Hexavalent Chromate has been classified as a human carcinogen by the EPA and OSHA.
