<p>Flat rolled semi-finished material made from an aluminum alloy has a degree of deformation of at least 50 % before a first intermediate soft annealing step and not more than 30 % before a final soft annealing step. The semi-finished material is drawn by 0.1-0.5 % after the final soft annealing step. The aluminum alloy contains alloying additions (in wt.%) 2-5 magnesium, = 0.5 manganese, = 0.35 chromium, = 0.4 silicon, = 0.4 iron, = 0.3 zinc, = 0.15 titanium. An independent claim is also included for a process for the production of a flat rolled semi-finished material made from an aluminum alloy.</p> |
