  • Aluminum alloy powder metal bulk chemistry formulation
    Patent number: 8920533
    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.
    Type: Grant
    Filed: October 6, 2009
    Date of Patent: December 30, 2014
    Assignee: GKN Sinter Metals, LLC
    Inventors: Donald Paul Bishop, Christopher D. Boland, Richard L. Hexemer, Jr., Ian W. Donaldson
