What is the difference between trivalent and hexavalent plating?
The key difference between trivalent and hexavalent zinc plating is that the trivalent zinc plating process has a high efficiency with a uniform distribution than the hexavalent zinc plating process. Zinc plating is a common process of protecting a wide range of materials.
Is Cr3 RoHS compliant?

Is chrome coating toxic?
The problem with traditional chrome plating Chromium contains Hexavalent chromium, which is a known carcinogen. The plating process uses lead, which can be absorbed through the skin and can cause liver, organ and brain damage. Cyanide is very toxic. It is used in the chrome-plating process and can be deadly to humans.
