Abstract: New 6xxx aluminum alloys having an improved combination of properties are disclosed. The new 6xxx aluminum alloy generally include from 0.30 to 0.53 wt. % Si, from 0.50 to 0.65 wt. % Mg wherein the ratio of wt. % Mg to wt. % Si is at least 1.0:1 (Mg:Si), from 0.05 to 0.24 wt. % Cu, from 0.05 to 0.14 wt. % Mn, from 0.05 to 0.25 wt. % Fe, up to 0.15 wt. % Ti, up to 0.15 wt. % Zn, up to 0.15 wt. % Zr, not greater than 0.04 wt. % V, and not greater than 0.04 wt. % Cr, the balance being aluminum and other elements.
