Abstract: Disclosed are high-strength aluminum alloys and methods of making and processing such alloys. More particularly, disclosed is a 6XXX series aluminum alloy exhibiting improved mechanical strength, formability, corrosion resistance, and anodized qualities. An exemplary method includes homogenizing, hot rolling, solutionizing, and quenching. In some cases, the processing steps can further include annealing and/or cold rolling.
