Pure copper powder, also known as red copper powder, red copper powder, and electrolytic copper powder, is an important non-ferrous metal powder. It is widely used in powder metallurgy, diamond tools, injection molding, sealing materials, chemical products, electrical and electrical materials and other industries. Pure copper powder is widely used in the preparation of paste and powder metallurgy industries. The product has the characteristics of high purity and good fluidity.
Powder metallurgy parts use pure copper powder as a sintering aid, with adjustable loose density and particle size, and can be mixed with different powders such as iron powder, nickel powder, manganese powder and graphite powder to produce high strength and high density Powder metallurgy parts.
