Zusammenfassung:	New 6xxx aluminum alloy sheet products are disclosed. The new 6xxx aluminum alloy sheet products may contain, for instance, from 0.95 to 1.25 wt. % Si, from 0.65 to 0.95 wt. % Mg, wherein (wt. % Mg)/(wt. % Si) is not greater than 0.99:1, from 0.50 to 0.75 wt. % Cu, from 0.02 to 0.40 wt. % Mn, and from 0.03 to 0.26 wt. % Cr, wherein (wt. % Mn)+(wt. % Cr) is at least 0.22 wt. %. The new 6xxx aluminum alloy sheet products may have a thickness of from 0.5 to 4.0 mm and may realize an improved combination of properties, such as an improved combination of two or more of strength, ductility (elongation), castability, fracture behavior and corrosion resistance.
