New aluminum alloys having magnesium and zinc are disclosed. The new magnesium-zinc aluminum alloys may include from 2.5 to 4.0 wt. % Mg, from 2.25 to 4.0 wt. % Zn, wherein (wt. % Mg/wt. % Zn)≥1.0, and wherein (wt. % Mg/wt. % Zn)≤1.6, from 0.20 to 0.9 wt. % Mn, from 0.10 to 0.40 wt. % Cu, up to 1.0 wt. % Li, up to 0.50 wt. % Fe, up to 0.50 wt. % Si, and optional secondary element(s), the balance being aluminum, optional incidental elements and impurities.

Aluminum-magnesium-zinc aluminum alloys

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&#xb0; F.
