Abstract: New 2xxx aluminum alloys having are disclosed. The new 2xxx aluminum alloys generally include 2.5-3.9 wt. % Cu, 0.82-1.20 wt. % Li, 0.5-2.0 wt. % Zn, 0.10-0.60 wt. % Mn, 0.05-0.35 wt. % Mg, from 0.05 to 0.50 wt. % of at least one grain structure control element, wherein the at least one grain structure control element is selected from the group consisting of Zr, Sc, Cr, V, Hf, other rare earth elements, and combinations thereof, up to 0.22 wt. % Ag, up to 0.15 wt. % Fe, up to 0.12 wt. % Si, and up to 0.15 wt. % Ti, the balance being aluminum, incidental elements and impurities. The new 2xxx aluminum alloys may realize an improved combination of two or more of strength, fracture toughness, elongation, and corrosion resistance.
