Abstract
A copper-rich metal shape is produced by forming a coherent forerunner shape consisting essentially of cupreous powder, said powder containing a proportion of copper oxide sufficient for facilitating the obtaining of a high sinter density in sintered porous mass, and in a reducing atmosphere at temperature that will sinter copper present, converting said forerunner shape into a porous sintered mass virtually devoid of copper oxide. Said porous mass can be worked so virtually full density if desired.
