A process for making an essentially lead-free screw machine stock alloy, comprising the steps of providing a cast aluminum ingot having a composition consisting essentially of about .55 to .70 wt.% silicon, about .15 to .45 wt.% iron, about .30 to .40 wt.% copper, about 0.8 to .15 wt.% manganese, about .80 to 1.10wt.% magnesium, about .08 to .14 wt.% chromium, nor more than about .25 wt.% zinc, about .007 to .07 wt.% titanium, about .20 to .8 wt.% bismuth, about .15 to .25 wt.% tin, balance aluminum and unavoidable impurities; homogenizing the alloy at a temperature ranging from about 900 to 1060°F for a time period of at least 1 hour; cooling to room temperature; cutting the ingot into billets; heating and extruding the billets into a desired shape; and thermomechanically treating the extruded alloy shape.
