FIELD: manufacture of forged or formed construction parts. SUBSTANCE: construction part is made of vanadium free aluminium alloy containing, mas. %: copper, 4.85-5.3; magnesium, 0.5-1.0; manganese, 0.4-0.8; argentum, 0.2-0.8; zirconium, up to 0.25; silicium, up to 0.1; ferrum, up to 0.1; aluminium and impurities, the balance. Alloy has relation copper/magnesium equal approximately to 5-9, preferably 6-7.5. Tension yielding strength of alloy at 20 C is approximately 77 kpound/sq.inch (5413 kg/sq.cm) or higher. Such alloy is suitable for forging or forming aircraft wheel and other parts used as wing portions for high-speed airplanes such as stringers or others. EFFECT: enhanced combination of strength and dynamic viscosity. 32 cl, 9 dwg, 9 tbl
