It is a neutral tin-copper alloy plating that does not contain cyanide compounds.
Traditionally, the plating for nickel allergy has primarily been copper-tin alloy plating using cyanide. This copper-tin binary alloy plating is a neutral nickel alternative plating solution that does not use any harmful substances such as cyanide compounds or fluorides. It is a non-magnetic plating with a shiny white appearance. For more details, please contact us.

Company information
We develop, manufacture, and sell surface treatment chemicals based on electrodeposition paint. All of our electrodeposition paints are lead-free and tin-free. We offer a wide range of applications, from decorative purposes to functional uses. For functional purposes, we have options for electrical insulation (epoxy-based), heat resistance (polyimide-based), non-contamination (fluorine-based), and photoresist (alkali-resistant), among others. In the plating sector, we provide tungsten alloy plating with excellent release properties for glass and resin, as well as nickel plating processes with excellent solder wettability. We pursue the potential of surface treatment technology and aim to create added value for our customers. We have obtained ISO 14001 certification and ISO 9001 certification (for electrodeposition paint). For more details, please visit our website.
