FIELD: metallurgy.
SUBSTANCE: invention relates to deformable alloys based on aluminum and can be used to protect space vehicles from micrometeorites and technogenic bodies. Alloy based on aluminum contains, mass %: zinc 5.8–11; magnesium 1.5–3.5; copper 0.1–3; manganese 0.1–0.5; at least one element from the group: beryllium, lanthanum, 0.0001–0.2 of each, at least two elements from the group: hafnium 0.05–1.0, titanium, zirconium, chromium, 0.05–0.3 each, and with the content of two elements, the choice is made from the group: titanium, zirconium, hafnium, optionally cerium, 0.0001–0.2, the rest is aluminum and inevitable impurities in the amount of not more than 0.7.
EFFECT: invention is aimed to increase resistance of alloys to impact.
