White bronze plating (CuSnZn)
The Rudolf Clauss GmbH & Co. KG specializes in different metal finishing methods and offers galvanic white bronze plating services as well.
This surface finish works with an alloy composed of 60 % copper, 30 % tin and 10 % zinc. White bronze derives its name from the color the metal has after processing – a bright, white, shiny color. Bronze plating is one of the galvanic methods and can be used on a variety of metals: steel, stainless steel, brass and copper. White bronze plating metals offers numerous advantages.
For instance, the galvanic process increases the electrical conductivity and the corrosion resistance. Moreover, the white alloy is tarnish resistant, antibacterial and does not cause allergic reactions.
In combination with nickel free materials, this process allows for the production of skin friendly objects and provides a helpful alternative to nickel. If you are interested in galvanic white bronze plating, the Rudolf Clauss GmbH & Co. KG is your perfect partner. The company will provide assistance as an experienced industry contact.
