Abstract:
New 6xxx aluminum alloys having an improved combination of properties are disclosed. Generally, the new 6xxx aluminum alloys contain 1.00-1.45 wt. % Si, 0.32-0.51 wt. % Mg, wherein a ratio of wt. % Si to wt. % Mg is in the range of from 2.0:1 (Si:Mg) to 4.5:1 (Si:Mg), 0.12-0.44 wt. % Cu, 0.08-0.19 wt. % Fe, 0.02-0.30 wt. % Mn, 0.01-0.06 wt. % Cr, 0.01-0.14 wt. % Ti, and ≤0.25 wt. % Zn, the balance being aluminum and impurities, wherein the aluminum alloy includes ≤0.05 wt. % of any one impurity, and wherein the aluminum alloy includes ≤0.15 in total of all impurities.
