Abstract (en)

[origin: EP1961840A1] Non-toxic electrolyte for electroplating consumer goods and technical equipment with bronze contains copper, tin and optionally zinc, all as water-soluble salts, and one or more phosphonic acid derivatives as complex formers. It is free from cyanides, thiourea derivatives and thiol derivatives. An independent claim is included for a method for electroplating consumer goods and technical equipment with bronze in which they are immersed in an electrolyte as described.
