Abstract (en)
[origin: EP2631317A1] A heat-treatable aluminum alloy chosen from aluminum-magnesium-silicon alloy, aluminum-zinc alloy or aluminum-zinc-magnesium alloy in the form of solution is subjected to annealing, obtained annealed alloy is quenched and subsequently precipitates are formed by hardening. The resultant aluminum alloy is subjected to artificial aging, porosity of the aged aluminum alloy is increased and resultant aluminum alloy is further subjected to aging process. Thus, the method for improving heat-curing ability of semifinished/finished product is enabled. Independent claims are included for the following: (1) usage of aluminum alloy; (2) aluminum alloy; and (3) semifinished/finished product.
