FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly, to wrought non-heat-treatable aluminium-based alloys intended for use in the form of deformed semi-finished products as structural materials. Alloy contains, wt%: magnesium 5.7-6.3, titanium 0.01-0.03, beryllium 0.0001-0.005, zirconium 0.05-0.12, scandium 0.18-0.26, manganese 0.2-0.55, iron 0.05-0.3, silicon 0.03-0.2, inevitable impurities: copper not more than 0.1, zinc not more than 0.1, the remaining impurities not more than 0.05 each and maximum 0.15 in total; aluminium - the rest, at the content of hydrogen in the alloy of 0.1-0.35 cm3 per 100 g of metal and the relation of the content of iron to silicon content equal to or more than 1.
EFFECT: technical result of the invention is improved strength characteristics of the alloy.
