Abstract (en)
[origin: EP2113576A1] The invention relates to foundry and rolling engineering. The inventive method for producing a structural material made of an aluminium-based alloy having the following component weighting ratio (%): 9.0-11.0 magnesium, 0.15-0.2 zirconium, 0.01-0.001 cobalt, 0.001-0.02 beryllium, aluminium being the rest, consists in producing a billet, in exposing it to heat treatment and in rolling said billet, wherein a melt used for producing the billet is crystallised in a rotating crystalliser with a gravitation factor ranging from 220 to 250 during the melt lifetime of 12-15 sec/kg.
