Abstract
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.
