AI-Mg-Si alloy sheet

The rolled product, in particular sheet product, prepared by the following successive steps: (A) casting an Al-Mg-Si alloy having the following composition (in wt .-%): 0.95 to 1.10 Si, 0.45 to 0.7 Mg, Cu 0.1 to 0.3, one or more of Zr, Mn, Cr and / or Ti, until a total of 0.02 to 0.14 Max. 0.4 Fe Max. 0.25 Zn, inevitable impurities each max. 0.05, total up to 0.20, Balance aluminum, (B) Diffusion annealing at least three hours at a temperature ranging from 530 ° C to 580 ° C, (C) hot rolling the alloy ingot or alloy slab to obtain an intermediate plate, (D) intermediate annealing of the intermediate sheet for 0.5 to 5 hours at a temperature ranging from 330 ° C to 400 ° C, (E) cold rolling of the intermediate plate in order to obtain a desired final thickness.
