Abstract
New 7xxx aluminum alloys alloys are disclosed. The new 7xxx aluminum alloys may include 5.0 - 9.0 wt. % Zn, 1.30 - 2.05 wt. % Mg, 1.10 - 2.10 wt. % Cu, wherein 2.55 ⿤ (wt. % Cu + wt. % Mg) ⿤ 3.85, at least one of (i) 0.03 - 0.40 wt. % Mn and 0.02 - 0.15 wt. % Zr, wherein 0.05 ⿤ (wt. % Zr + wt. % Mn) ⿤ 0.50, up to 0.20 wt. % Cr, up to 0.20 wt. % V, up to 0.20 wt. % Fe, up to 0.15 wt. % Si, up to 0.15 wt. % Ti, and up to 75 ppm B, the balance being aluminum, incidental elements and impurities. The new 7xxx aluminum alloys may be in the form of a 7xxx aluminum alloy sheet product having a thickness of from 0.5 to 4.0 mm and comprising at least 15 vol. % recrystallized grains. The new alloys may realize an improved combination of at least two of strength, elongation, fracture behavior and corrosion resistance.
