Abstract:
     It provides a cyanide-free bronze-plating bath and a cyanide-free brass-plating bath. The bronze bath is composed of the Cu (II) compound with Stannate Na2Sn(OH)6 or K2 Sn(OH)6, ethylene glycol and caustic alkali NaOH or KOH; The brass-plating is composed of the same Copper compound with Zinc oxide, glycol and caustic alkali. Both baths have good dispersing power, a wide range of cathodic current density and are able to electrodeposite the bronze coating with low Tin content and the brass coating with required Cu-Zn ratio.
