FIELD: metallurgy of alloys. SUBSTANCE: aluminium-base alloy has the following components, wt.-%: magnesium, 5.8-6.8; zirconium, 0.02-0.15; beryllium, 0.0001-0.01; scandium, 0.2-0.5; cerium, 0.001-0.01; boron, 0.001-0.01; at least one metal from the group containing chrome, titanium, vanadium, 0.02-0.2; and aluminium, the balance. Method ensures to enhance basic metal strength, improve indices of superplasticity, enhance the strength of welding structure, decrease weight and others. EFFECT: improved quality and properties of alloy. 2 tbl
