Abstract
A powder metal mixture is disclosed that provides improved mechanical properties for parts made from powder metal, such as cam caps. The powder metal mixture, upon sintering, forms an S phase intermetallic in the Al—Cu—Mg alloy system. The S phase is present in a concentration that results in an enhanced response to cold work strengthening of the powder metal part. Further, by minor adjustments to certain alloy elements, such as tin, the tensile properties of the resultant part may be adjusted.
