Abstract

Free-machining aluminum alloys are disclosed containing effective amounts of tin and indium. The tin and indium additions are especially adapted for use as free-machining constituents in aluminum alloys, such as AA2000 and AA6000 series aluminum alloys. The additions can be used in place of bismuth and lead in currently available free machining alloys. In alloys containing bismuth and tin, the indium can be used to replace the bismuth. A method of producing a free-machining aluminum alloy product also is described.
