Copper powder production methods are divided into: electrolysis, water atomization and oxidation reduction method. Electrolysis production has a long history, mature technology. Production of copper powder, with a dendritic micro-shape, as well as surface developed, high purity, good shape and other characteristics, however, with electrolysis production.

Copper powder has a serious pollution of the environment and high energy consumption shortcomings. In the production of copper powder, can replace the electrolysis method, when the devaluation atomization method. Water atomization milling, coupled with the subsequent treatment of redox and other processing technology, successfully developed in line with environmental protection needs of the low density of atomized copper powder.
