FIELD: metallurgy.
SUBSTANCE: invention relates to alloys based on aluminum, intended for making deformed semi-finished products in the form of sheets, sheet stamping, for use in individual armor protection means. Aluminium-based alloy contains following, wt %: Zn—10; Cu—1.8; Mg—2.7; Cr—0.17; Mn—0.40; Zr—0.15; Hf—0.3; Be—0.003; ZrB2—0.03; ZrO2—0.03; Al is rest.
EFFECT: alloy is characterized by high strength, ductility and viscosity, including at moderate elevated temperatures, as well as high manufacturability of semi-products and articles.
