Claim:
1. A method of producing a powder metal part, the method comprising: forming an aluminum—zirconium melt in which a zirconium content of the aluminum—zirconium melt is less than 2.0 percent by weight; powderizing the aluminum—zirconium melt to form a zirconium-doped aluminum powder metal; mixing the zirconium-doped aluminum powder metal with at least one other powder metal including tin thereby forming a mixed powder metal; and compacting and sintering the mixed powder metal to form the powder metal part; wherein a quantity of zirconium in the powder metal part is substantially equal to a quantity of zirconium found in the zirconium-doped aluminum powder metal used to form the powder metal part.
