High strength and high formability aluminum alloy resistant to natural age hardening and method for producing the same

摘要

High strength, highly deformable aluminum alloys and methods of making and processing such alloys are disclosed. More specifically, heat-treatable aluminum alloys exhibiting improved mechanical strength and formability are disclosed. Processing methods include casting, homogenization, hot rolling, solution treatment, pre-aging, and possibly pre-strain. In some cases, the processing step may further include cold rolling and / or heat treatment. [Selection diagram] Fig. 1
