Abstract
A new aluminum based alloy having properties which mimic homogenized DC cast 3003 alloy and a low-cost method for manufacturing it are described. The alloy contains 0.40% to 0.70% Fe, 0.10% to less than 0.30% Mn, more than 0.10% to 0.25% Cu, less than 0.10% Si, optionally up to 0.10% Ti and the balance Al and incidental impurities. The alloy achieves properties similar to homogenized DC cast 3003 when continuously cast followed by cold rolling and if desired annealing at final gauge. Suprisingly no other heat treatments are required.
