Aluminum wheels with non-cyanide electroplating copper plating solution

Aluminum Sheet cyanide copper plating solution , characterized by comprising 180 ~ 220g / L of copper sulfate , 30 ~ 80mL / L sulfuric acid , 80 ~ 160ppm chloride , 5.0 ~ 10.0mL / L open cylinder agent UM, 0.4 ~ 0.6mL / L filling agent UA, 0.4 ~ 0.6mL / L brightener UB and water .

Plating method comprising immersing the workpiece first aluminum wire sink zinc cyanide displacement reaction occurs in solution in the aluminum wheel surface zinc layer of the workpiece ; plug it into the cathode copper cyanide plating solution, with phosphor as an anode , in aluminum wheels copper surface of the workpiece . The present invention deposition speed, high filling plating , coating easy to produce pinholes, low internal stress , rich extensibility and will not pollute the environment.
