Abstract: New aluminum alloys are disclosed and generally include 0.6-1.4 wt. % Si, 0.25-0.90 wt. % Mg, wherein the ratio of wt. % Si to wt. % Mg is from 1.05:1 to 5.0:1, 0.25-2.0 wt. % Cu, 0.10-3.5 wt. % Zn, 0.01-1.0 wt. % Fe, up to 0.8 wt. % Mn, up to 0.25 wt. % Cr, up to 0.20 wt. % Zr, up to 0.20 wt. % V, and up to 0.15 wt. % Ti, wherein the total of Fe+Mn+Cr+Zr+V+Ti is not greater than 2.0 wt. %, the balance being aluminum and impurities. The new aluminum alloys may include Q phase precipitates. In some embodiments, the solvus temperature of the Q phase precipitates is not greater than 950° F.
