Steel Cord Brass Plating Line
1. Brief description
Brass plating is the application of a few µm thick zinc to the surface of copper - zinc alloy parts. During galvanic brass plating, the alloy usually contains 60-70% copper. The colour of the coating varies depending on the composition: from golden-yellow to grey-green. In the air, the coating fades quickly and varnish protection is required.
Brass is used to protect products from corrosion, to create an intermediate layer when nickel-plating or tinning steel parts. Brass coatings of steel parts are often used for decorative purposes.
