This process does not contain sodium cyanide or cuprous cyanide, nor does it contain phosphorus. The wastewater treatment is simple and meets environmental protection requirements. This process is compatible with cyanide copper plating solution and can be directly transferred to the barrel on the basis of cyanide copper plating solution. It is suitable for the undercoat of zinc alloy, aluminum alloy, neodymium iron boron, and steel substrates. The plating solution is stable and easy to operate, and is suitable for rolling plating, hanging plating, and continuous electroplating.
