  • CYANIDE-FREE ELECTROPLATING BATHS FOR WHITE BRONZE BASED ON COPPER (I) IONS
    Publication number: 20160298249
    Abstract: Copper alloy electroplating baths include one or more sources of copper (I) ions and one or more sources of tin ions to electroplate copper/tin alloys of mirror bright white bronze. The copper alloys may also include one or more sources of silver ions to electroplate ternary alloys of bright white bronze containing copper/tin/silver. The copper alloy electroplating baths are cyanide-free.
