DEFORMED ALUMINIUM-BASED ALLOY Russian patent published in 2021 - IPC C22C21/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to deformed aluminium-based alloys intended for use as deformed semi-finished products, mainly in the form of pressed rods, as an electrically conductive structural material mainly for current-carrying elements in aerospace engineering, shipbuilding, transport engineering and other industries, and as a preform for the production of electrical wires. The deformed aluminium-based alloy contains, wt %: scandium 0.15-0.28, zirconium 0.05-0.15, iron 0.01-0.06, unavoidable impurities, including magnesium, not more than 0.05, manganese not more than 0.02, silicon not more than 0.05, copper not more than 0.05, zinc not more than 0.05, titanium not more than 0.05, chromium not more than 0.02 for their total content of not more than 0.15, aluminium the rest, while observing the ratio between the content of zirconium and scandium of 0.25 to 0.75.

EFFECT: increasing the strength and electrical conductivity of the material.
