Copper Powder

Copper Powder exhibits high electrical conductivity and is commonly used in applications requiring efficient charge transport and thermal management. Its utility in conductive pastes and printed electronics supports advances in microfabrication and low-temperature processing. In research and laboratory environments, copper powder is explored for additive manufacturing (AM mfg) techniques such as binder jetting (BJ) and directed energy deposition (DED), with ongoing efforts to optimize its behavior in fine powder form. It also contributes to catalysis research through copper-based oxides and alloy structures used in fuel cell studies. While not ideal for thermoelectric devices, it plays a role in composite development and thermal interface design in materials science.
