Abstract

A zirconium-doped aluminum powder metal and a method of making this powder metal are disclosed. The method of making includes forming an aluminum—zirconium melt in which a zirconium content of the aluminum—zirconium melt is less than 2.0 percent by weight. The aluminum—zirconium melt then powderized to form a zirconium-doped aluminum powder metal. The powderization may occur by, for example, air atomization.
