HIGH-STRENGTH ALUMINIUM-BASED ALLOY Russian patent published in 2018 - IPC C22C21/10 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, in particular the production of casting materials based on aluminum, and can be used to obtain critical products operating under high loads used for the automotive industry, sports equipment and others. High-strength alloy based on aluminum contains, wt.%: zinc 5–8, magnesium 1.5–2.1, calcium 0.10–1.9, iron 0.08–0.5, titanium 0.01–0.15, silicon 0.08–0.9, nickel 0.2–0.4, cerium 0.2–0.4, zirconium 0.08–0.15, scandium 0.08–0.15, aluminum is the rest, however, the zinc content in the aluminum solution and secondary discharge is at least 4 wt.%.

EFFECT: technical result is an increase in the strength properties of the alloy and its products due to the formation of secondary precipitates of the hardening phase by means of precipitation hardening.
