Aluminum powder compositions intended for powder metallurgy applications are provided. The powder compositions contain aluminum and aluminum alloys or blends made from elemental powders, admixed with a polyethylene lubricant. The polyethylene admixture eases the compaction of powders and the ejection of parts. As compared to other conventional admixed lubricants used for Al powder metallurgy applications, polyethylene allows to obtain parts with higher green and sintered strengths. Proper delubrication prior to sintering is of importance.
