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.
