Abstract

See full text

The present invention relates to metallurgy of high-strength cast and wrought alloys based on aluminum, and can be used in missioncritical designs operable under load, in the transport field, sports industry, casings for electronic devices, and other industrial sectors. The technical result aims to enhance mechanical characteristics of articles produced from the alloy by precipitation hardening caused by secondary phases in the age-hardening process while providing high workability during casting. The claimed high-strength alloy comprises zinc, magnesium, nickel, iron, copper, zirconium, and at least one metal selected from a group consisting of titanium, scandium and chromium, with the following amounts in, 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; chromium 0.04-0.15; and the remainder being aluminum, wherein iron and nickel form aluminides of the Al9FeNi phase, which originates from eutectic transformation and represents at least 2 vol %.
