FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy of light alloys intended for fabrication of deformed semi-products in the form of plates, sheets, die forgings and profiles for use in aerospace industry. Aluminum-based alloy contains, wt%: magnesium 5.0–6.0, scandium 0.06–0.16, beryllium 0.0002–0.005, manganese 0.15–0.6, zirconium 0.01–0.12, zinc 0.1–0.6, iron 0.02–0.15, silicon 0.01–0.1, at least two elements selected from the group: erbium 0.03–0.16, hafnium 0.01–0.16, ytterbium 0.03–0.16, aluminum – the rest.
EFFECT: invention is aimed at creation of aluminum-based alloy of Al-Mg system, having high properties at temperatures higher than 70 °C.
