Abstract
A free-machining alloy is disclosed containing bismuth, tin and indium. The free-machining constituents act as low melting point compounds for machining and are specially adapted for use in aluminum alloys such as AA6000 series and AA 2000 series alloys. The bismuth, tin and indium are effective replacements for the lead and bismuth addition used previously to improve machinability.
