FIELD: metallurgy of aluminum base alloys used for making semi-finished products and products used as construction materials in aerospace engineering.
SUBSTANCE: aluminum-base alloy and product of such alloy contain next ingredients, mass%: lithium, 1.6 - 1.9; copper, 1.3 - 1.5; magnesium, 0.7 - 1.1; zirconium, 0.04 - 0.2; beryllium, 0.02 -0.2; titanium, 0.01 - 0.1; nickel, 0.01 - 0.15; manganese, 0.01 - -.2; gallium, up to 0.001; zinc, 0.01- 0.3; sodium, up to 0.0005; calcium, 0.005 - 0.02; and at least one element selected from group including vanadium, 0.005 - 0.01; scandium, 0.005 - 0.01; aluminum, the balance. Such alloy and products of such alloy feature enhanced ductility.
EFFECT: improved manufacturability, less loss of yield at making semi-finished products and articles, possibility for making thin sheets, thin-wall shapes and forged pieces, lowered labor consumption for making products.
