摘要
Cyanide-free plating baths for the electrodeposition of copper alloys comprise aqueous alkaline mixtures which contain copper and either lead or tin ions and a chelating agent selected from glucoheptonic acid and its salts. Processes for electroplating using the bath and for removing the metal ions from the spent baths by pH adjustment are also disclosed.
