The invention provides a new aluminum-based alloy having properties which mimic homogenized DC cast 3003 alloy, and a low-cost method for manufacturin g the alloy. 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 0.1 0 % Ti, and the balance Al and incidental impurities. The alloy achieves properties similar to homogenized DC cast 3003 alloy when continuously cast, followed by cold rolling and, if desired, annealing at final gauge. Surprisingly, no other heat treatments are required.
