Copper Powder for Electrification: Why Morphology, Purity, and Packing Density Are Now Engineering Variables

Sintered contacts, additive manufactured heat exchangers, EV motor components, and conductive pastes each require a different copper powder. This article explains why morphology, particle size distribution, oxygen content, and packing density are engineering variables, and how to specify them correctly for electrification applications.
