General description

Copper powder is a metal based powder that can be produced by electrolytic and non-electrolytic techniques. These processes include spray pyrolysis, chemical reduction in the presence of reducing agents, solvothermal and hydrometallurgical methods, and atomization.

Application

Copper (Cu) based powder can be used for a wide range of industrial applications. Its electrical properties and thermal characteristics make it useful in the development of electronic and electrical devices. It can also be used for self-lubricated bearings, brazing, mechanical plating, and cold soldering.
