Copper pyrophosphate is mainly used for cyanide-free plating and is the main salt for supplying copper ions in the bath. Copper primers for decorative protective layers and partially carburized coatings for carburized parts. Used for pyrophosphate copper plating, bronze plating, nickel plating, copper-plated tin alloys, and tungsten alloys, and also used for analysis reagents. Copper pyrophosphate is mainly used as the main salt of copper pyrophosphate electroplating. Copper pyrophosphate is the main source of copper ions in the plating bath. The copper content in commercial copper pyrophosphate is about 38%, and the copper content in general copper plating bath is 20-25 g/L. The copper content in bright copper plating bath is controlled at 25 ~35g/L. If the content of copper in the plating solution is too low, the plating is poor in brightness and flatness, and the allowable operating current density range is small; if the content of copper in the plating solution is too high, the content of potassium pyrophosphate must be increased accordingly, resulting in increased loss of solution. , increase production costs. Copper pyrophosphate is generally controlled at 60 ~ 90g / L is appropriate.
