Abstract (en)
The invention relates to a method of manufacturing an aluminium alloy sheet product, and comprising the steps of: (i) providing a feedstock for rolling and having a gauge in the range of 4 mm to 30 mm and being made from an aluminium alloy having at least 2.5% to 6% Mg and 0.05 to 1% Sc; (ii) cold rolling of the feedstock to a cold rolled sheet product having a gauge in the range of 0.8 mm to 6 mm; and (iii) annealing of the cold rolled sheet product at a temperature in the range of 225°C to 400°C.
