Zinc Trivalent Chromate Plating

Zinc chloride plating is a plating process without the use of highly toxic cyanide. Cody Metal Finishing is completely cyanide free, in all of our processes.

Chromate conversion coating is a type of coating used to protect and seal  zinc, cadmium, copper, silver, magnesium, and tin alloys.  

Zinc chromate plating is primarily used as a corrosion inhibitor, a primer, and a decorative finish.

The trivalent process is a post treatment dip that seals and prevents oxidation and is ROHS COMPLIANT. The zinc trivalent chromate process is named after the chromate found in the chromic acid, used in the bath.
