  • Method of producing a metal component interacting by way of a sliding surface with a friction partner for a drive assembly
    Patent number: 6418901
    Abstract: A method of producing a metal component interacting by way of a sliding surface with a friction partner, for a drive assembly, includes forming the component from an aluminum-silicon-copper-magnesium alloy. The alloy has 12-15 wt. % silicon, 2.5-3.5 wt. % copper, and 0.4-0.8 wt. % magnesium. The particle size for the silicon is between 4 &mgr;m and 30 &mgr;m. The sliding surface of the component in the firm condition is compressed by calibrating.
