Spherical copper powder refers to copper powder which is spherical under scanning electron microscope (SEM). Compared with irregular copper powder, spherical copper powder has excellent fluidity. According to different particle sizes, spherical copper powder can be divided into nano spherical copper powder, submicron spherical copper powder, and micron spherical copper powder. Among them, micron grade spherical copper powder above 10 um is mainly produced through gas atomization technology, which can control the required particle size through a mesh screen. Spherical copper powder below 10 um is mainly produced through special processes.

Spherical Copper Powder Application

Spherical copper powders with different particle sizes have different application terminal performance, and also have different cost and economic benefits. Therefore, depending on the particle size, spherical copper powder can be used in a variety of situations:

Spherical Copper Powder above 10 um

Spherical copper powder with a size of more than 10 um is mainly produced through gas atomization technology, and the particle size can be controlled through screen screening. The common particle sizes are 10-45 um, 15-53 um, 45-105 um, 45-150 um, etc.  It is mainly used in 3D printing/additive manufacturing, thermal spraying, laser cladding, injection molding and other occasions.
