Abstract (en)
[origin: EP1930478A1] The present invention relates to an electrolyte composition as well as a method for the deposition of a quaternary copper alloy on a substrate. The electrolyte composition according to the invention comprises besides the alloying metals copper, tin and zinc, at least one metal from the group consisting of indium, gallium and thallium. The electrolyte composition according to the invention enables to deposit white bronze layers which present a high corrosion resistance and hardness and are free of noxious heavy metals.
