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.

6XXX aluminum alloys

New 6xxx aluminum alloy strips having an improved combination of properties are disclosed. The new 6xxx new aluminum alloy strips are rolled to a target thickness in-line via at least a first rolling stand and a second rolling stand. In one approach, the 6xxx new aluminum alloy strips may contain 0.8 to 1.25 wt. % Si, 0.2 to 0.6 wt. % Mg, 0.5 to 1.15 wt. % Cu, 0.01 to 0.2 wt. % manganese, 0.01 to 0.2 wt. % iron; up to 0.30 wt. % Ti; up to 0.25 wt. % Zn; up to 0.15 wt. % Cr; and up to 0.18 wt. % Zr.
