FIELD: metallurgy. ^ SUBSTANCE: the present innovation deals with obtaining aluminum-based alloys necessary for manufacturing stampings, particularly those of automobile wheels disks. The alloy in question has got the following composition, weight%: copper 0.8-2.2; magnesium 1.2-2.6; manganese 0.2-0.6; iron <=0.25; silicon <=0.20; zinc 5.0-6.8; titanium <=0.1; chromium 0.08-0.17; zirconium 0.01/0.12; boron 0.0008-0.005; antimony 2.5-3.5; indium 2.5-3.5; boron 0.4-0.5; hydrogen (0.3-4.1)10-5, aluminum - the rest. The alloy in question is of optimal combination of strength and plasticity that guarantee the required level of performance characteristics of automobile wheels disks, the decrease of their weight in combination with high technological effectiveness at volumetric stamping, especially complex-shaped articles. ^ EFFECT: higher strength and plasticity of the alloy. ^ 2 cl, 1 ex, 3 tbl |
