The disclosure relates to an aluminum alloy plate having a final thickness of 3 inch or more, and a method for manufacturing same. In the method, an aluminum alloy with a chemical composition of in weight percent: Mg 4.0 to 5.2, Mn 0.4 to 1.0, Zn≤0.3, Zr≤0.3, Cr≤0.3, Ti≤0.3, Fe<0.50, Si<0.45, Cu<0.25, other elements and unavoidable impurities each <0.05 total <0.20 balance aluminum, is cast, preheated and/or homogenized, hot rolled, cold rolled with a cold rolling reduction of 3 to 10%, and stretched directly after cold rolling with a permanent elongation of 0.7 to 5% in the direction of stretching.

Thick Al—Mg alloy rolled product suitable for armor plate applications

The invention concerns a method for improving aluminium alloy blank tensile yield stress and formability comprising the successive steps of: providing a 6xxx series aluminium alloy slab; optionally homogenizing the slab; hot rolling and optionally cold rolling the slab to obtain a sheet; solution heat treating and quenching the sheet; cold rolling the sheet with at least 20% cold work reduction; cutting the sheet into blanks; flash annealing a portion of the flange of the blanks at a temperature between 360° C. and 480° C. for a time sufficient to obtain recrystallization of the portion of the flange and cool to a temperature of less than 100° C. The improved blanks and the stamped product and painted stamped products obtained by the method of the invention are particularly useful for automotive applications because of their high strength.
