Alexandria Plating Industries, Inc. has developed a Tri-metal alloy consisting of copper, tin and zinc that is also referred to as “white bronze,” thanks to its color, which is often compared to bright/satin nickel or silver. The bright white finish of tri-metal plating can be used as an undercoat with palladium, palladium/nickel, silver or gold products or as a topcoat with those finishes.
Tri-metal or white bronze plating creates a non-toxic, non-magnetic deposit that is highly resistant to corrosion. This metal finishing application has low porosity and a low coefficient of friction. Lead free Tri-metal plating is outstanding for solder applications. Since white bronze plating is non-magnetic, it is often used for applications instead of nickel. It has excellent wear resistance. Because of its corrosion protection features, tri-metal is used in a variety of commercial and consumer industries:
