Abstract
Improved aluminum particulate suitable for powder metallurgy applications is produced by wet-milling particulate aluminum in an inert atmosphere in the presence of a predetermined amount of oxygen to thereby comminute the aluminum into finer particles while oxidizing the new surfaces of such particles and then, after the supply of oxygen is exhausted, welding together such particles by further milling to provide a larger aluminum particle having aluminum oxide dispersed therein.
