description The present invention relates to the field of metallurgy of high-strength cast and wrought alloys based on aluminium, and can be used for producing articles used in mission-critical designs operable under load, as well as in the transport field, sports industry and sports equipment, for producing casings for electronic devices, and in other engineering industries and industrial sectors. The technical result aims to enhance mechanical characteristics of the articles produced from the alloy by virtue of the precipitation hardening caused by formation of secondary phases in the process of the age hardening, while providing high workability during casting ingots and castings. The claimed high-strength alloy based on aluminium comprises zinc, magnesium, nickel, iron, copper and zirconium, wherein it further comprises at least one metal selected from a group comprising titanium, scandium and chrome, with the following component ratios, wt %: zinc 3.8-7.4; magnesium 1.2-2.6; nickel 0.5-2.5; iron 0.3-1.0; copper 0.001-0.25; zirconium 0.05-0.2; titanium 0.01-0.05; scandium 0.05-0.10; chrome 0.04-0.15; and the remainder being aluminium, wherein iron and nickel advantageously form aluminides of the Al 9 FeNi phase, which originates from eutectic transformation and represents a volume percentage of at least 2 vol%.
