STRUCTURAL DEFORMABLE THERMALLY HARDENABLE ALUMINUM-BASED ALLOY

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to metallurgy, particularly to deformable thermally non-reinforced aluminium-based alloys intended for use in the form of deformed semi-products, mainly large sections, as structural material. Structural deformable thermally non-reinforced alloy based on aluminium contains components in following ratio, wt. %: magnesium 6.0–6.3, titanium 0.01–0.03, beryllium 0.0002–0.002, zirconium 0.07–0.12, scandium from more than 0.26 to 0.28, cerium 0.0002–0.0009, manganese from more than 0.5 to 0.6, iron and silicon 0.05–0.08, unavoidable impurities in amount of not more than 0.1, with content of not more than 0.05, aluminium is the rest, wherein ratio of iron content to silicon content is equal to or greater than one.;EFFECT: higher strength characteristics of alloy.;1 cl, 2 tbl, 1 ex
