Abstract
A process for producing finely divided spherical copper copper alloy powders comprises forming an aqueous solution of copper and alternatively other metal values forming a reducible metallic material from the solution, reducing the material to metal powder particles, subjecting the metal particles to a high temperature zone to melt a portion of the metal powder particles and to form droplets and cooling the droplets to form an essential spherical metal alloy particles.
