Abstract (en)
[origin: EP1098009A2] Aluminum wrought alloy of the AlMgSi type contains alloying additions of (in wt.%): 0.6-2.0 magnesium, 0.6-3.0 silicon, 0.6-1.5 tin, 0.4-1.0 manganese, maximum 0.25 chromium and titanium, and impurities containing maximum 0.4 iron, maximum 0.1 copper and maximum 0.2 zinc. An Independent claim is included for a process for the production of a continuously cast object made of the aluminum wrought alloy of the AlMgSi type comprising solution annealing during extrusion, quenching the extruded object and hardening.
