FIELD: metallurgy. SUBSTANCE: invention relates to base-base deformable alloys designated for application as structural material. Invention proposes alloy comprising the following components, wt.-%: copper 4.4-5.4; magnesium, 0.45-0.8; manganese, 0.4-0.8; titanium, 0.03-0.15; zirconium, 0.05-0.20; vanadium, 0.05-0.15; molybdenum, 0.01-0.15; silicon, 0.03-0.25; silver, 0.4-0.8; germanium, 0.05-0.20; nickel, 0.01-0.50; iron, 0.01-0.5; aluminum, the balance, and total content of manganese, titanium, zirconium, vanadium and molybdenum must be 0.55-1.0. Invention provides enhancing the strength indices of semifinished products and members in thermally treated state at room and increased temperatures being at short-term and prolonged loading that results to increasing useful life of aircrafts. EFFECT: valuable properties of alloy. 2 tbl, 1 ex |
