High strength and highly formable aluminum alloys resistant to natural age hardening and methods of making the same

A method of producing an aluminum alloy metal product, the method comprising;

• casting an aluminum alloy to form a cast aluminum alloy product, wherein the aluminum alloy comprises 0.6-1.1 wt. % Cu, 0.6-1.1 wt. % Si, 0.7-1.2 wt. % Mg, up to 0.25 wt. % Cr, up to 0.35 wt. % Mn, 0.15-0.3 wt. % Fe, up to 0.25 wt. % Zr, up to 1.0 wt. % Zn, up to 0.1 wt. % Ti, up to 0.04 wt. % Ni, and up to about 0.15 wt. % of impurities, and Al;
• homogenizing the cast aluminum alloy product;
• hot rolling the cast aluminum alloy product to produce a sheet, plate, or shate;
• solutionizing the sheet, plate, or shate at a temperature between about 520° C. and about 580° C.;
• pre-aging the sheet, plate, or shate;
• coiling the sheet, plate, or shate, and
• aging the sheet, plate, or shate at a temperature of from 180° C. to 225° C.,
• wherein an annealing step is not performed while processing the sheet, plate, or shate.
