The 2219 aluminum alloy is a heat-treated strengthened deformed aluminum alloy. After solution aging treatment, the mechanical properties of the aluminum alloy are greatly improved, and the plastic deformation is also accompanied by the deformation strengthening of the aluminum alloy. 2219 aluminum alloy is mainly used in the production of melon structure of aerospace rocket fuel storage tanks in China. The melon parts are mainly formed by drawing a large aluminum alloy sheet.
