  • Aluminum alloy powder formulations with silicon additions for mechanical property improvements
    Patent number: 11273489
    Abstract: The mechanical properties and thermal resistance of a sintered component made from an Al—Cu—Mg—Sn alloy powder metal mixture can be improved by doping the Al—Cu—Mg—Sn alloy powder metal mixture with a silicon addition. Silicon is added as a constituent to the Al—Cu—Mg—Sn alloy powder metal mixture. The Al—Cu—Mg—Sn alloy powder metal mixture is compacted to form a preform and the preform is sintered to form the sintered component.
    Type: Grant
    Filed: November 29, 2018
    Date of Patent: March 15, 2022
    Assignee: GKN Sinter Metals, LLC
    Inventors: Donald Paul Bishop, Richard L. Hexemer, Ian W. Donaldson, Randy Williams Cooke
  • Aluminum alloy powder metal with transition elements
    Patent number: 10870148
    Abstract: A transition element-doped aluminum powder metal and a method of making this powder metal are disclosed. The method of making includes forming an aluminum-transition element melt in which a transition element content of the aluminum-transition element melt is less than 6 percent by weight. The aluminum-transition element melt then powderized to form a transition element-doped aluminum powder metal. The powderization may occur by, for example, air atomization.

  • Aluminum powder metal alloying method
    Patent number: 9533351
    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.
