Copper Powder

Copper powder is widely used in diamond tools, electrocarbon products, powder metallurgical products, fricition materials, chemical catalysts, electronic materials and other industries. Copper powder can be divided into electrolytic copper powder and atomized copper powder.

The copper alloy powder is mostly spherical or spheroidal in shape, and it has high fluidity and high bulk density. This kind of powder is widely used in powder metallurgy oil bearing, diamond tools, filters, powder metallurgy products and bearing materials.

Electrolytic Copper powder

The electrolytic copper powder is light rose red dendritic. The copper powder produced by electrolysis has high purity and tree branched particles. After subsequent treatment, the dendritic shape is slightly rounded, has a good forming character, and has good electrical conductivity and thermal conductivity. It is widely used in the production of diamond tools, electric carbon products, friction materials, powder metallurgy products and conductive inks, and also used in electrical and electronic industries.
