ABSTRACT:
This disclosure is directed to an aluminum-lead-copper alloy and to methods for its preparation. The alloy may comprise, for example, 50 to 95 percent aluminum, with the remainder being copper and lead. The lead and copper may be separately melted and poured into superheated molten aluminum or preferably, lead-copper alloys may be made and added to the molten aluminum. The aluminum-lead-copper alloy is intended to have a fine and even dispersion of the phases and properties which make it suitable for bearings and bushings. Aluminum-lead alloys are also disclosed herein.
