Copper Powder Overview
Copper powder is a versatile material utilized across various industries, including diamond tools, electrocarbon products, powder metallurgy, friction materials, chemical catalysts, and electronic components. It is categorized into two main types: electrolytic copper powder and atomized copper powder.
Copper Alloy Powder
Copper alloy powder generally features a spherical or spheroidal shape, which contributes to its excellent fluidity and high bulk density. This type of powder is commonly used in powder metallurgy applications such as oil bearings, diamond tools, filters, and other bearing materials.
Electrolytic Copper Powder
Electrolytic copper powder is characterized by its light rose-red, dendritic form. Produced through electrolysis, this powder boasts high purity and distinctive tree-like branching particles. While initially dendritic, the particles tend to become slightly rounded after processing. This type of copper powder is prized for its excellent forming properties, electrical conductivity, and thermal conductivity. It is widely applied in manufacturing diamond tools, electric carbon products, friction materials, powder metallurgy products, and conductive inks, as well as in various electrical and electronic applications.
