What is Brass Plating?

Brass, which is an alloy of copper and uzinc, is the most widely used alloy electroplate. Brass plating primarily is used for decorative applications, but it is also used for engineering applications such as for plating steel wire cord for steel-belted radial tires. Although all of the alloys of copper and zinc can be plated, the brass alloy most often used includes 70 to 80 percent copper, with the balance zinc. Typical brass plating baths include 34 g/L of copper cyanide and 10 g/L of zinc cyanide. Other bath constituents include sodium cyanide, soda ash, and ammonia.
