BRONZEX™ SW-SP is an alkaline, cyanide electroplating process for barrel applications, with a fully organic brightening system, producing a white bronze ternary alloy (copper-tin-zinc) deposit. It can be used as a topcoat or undercoat to palladium, gold, and other precious metals, as well as trivalent chromium.

Decorative applications

BRONZEX SW-SP creates a lustrous and exceptionally white coating without nickel, addressing allergy concerns linked to nickel plating. This makes it an outstanding hypoallergenic choice for nickel-free uses in the decorative sector.

Functional applications

Thanks to the deposit hardness, wear and corrosion resistance, and solderability BRONZEX SW-SP can also be used for technical applications such as connectors.
