FIELD: nonferrous metallurgy. SUBSTANCE: invention provides refractory deformable aluminum-based alloys intended for use as structural material in heat-exposed aircraft parts, e.g. in engine parts or in elements of parts of supersonic aircraft boarding. Alloy and products therefrom contain following components, wt %: copper 5.8-6.8, manganese 0.4-0.8, titanium 0.05-0.15, zirconium 0.10-0.20, vanadium 0.01-0.20, germanium 0.10-0.20, nickel 0.01- 0.50, iron 0.01-0.50, silicon 0.01-0.30, and aluminum - the balance. EFFECT: improved cracking- and heat-resistance values. 3 cl, 2 tbl |
