ABSTRACT:
A method of press quenching a 6020 aluminum alloy comprising the steps of providing an ingot or billet of 6020 aluminum alloy consisting essentially of about 0.5 to about 0.6% silicon, about 0.7 to about 0.8% magnesium, about 0.55 to about 0.65% copper, about 0.35 to about 0.45% iron, about 0.01 to about 0.04% manganese, about 1.05 to about 1.15% tin, and about 0.04 to about 0.06% chromium; homogenizing the billet, cooling the billet, reheating the billet, extruding the billet, quenching the extrusion, and artificially aging the extrusion. The alloy has enhanced productivity, strength, and machinability and can be used as a direct replacement for lead containing alloy 6262 T-6.
