Abstract: New 6xxx aluminum alloy bodies and methods of producing the same are disclosed. The new 6xxx aluminum alloy bodies may be produced by preparing the aluminum alloy body for post-solutionizing cold work, cold working by at least 25%, and then thermally treating. The new 6xxx aluminum alloy bodies may realize improved strength and other properties.
