WROUGHT THERMALLY NON-HARDENED ALUMINIUM-BASED ALLOY, AND ITEM MADE FROM IT Russian patent published in 2010 - IPC C22C21/06 

FIELD: metallurgy.

SUBSTANCE: there proposed is wrought thermally non-hardened aluminium-based alloy and item made from it, which contain components at the following ratio, wt %: magnesium 6.2-7.2, scandium 0.20-0.40, manganese 0.7-1.2, chrome 0.05-0.20, zirconium 0.05-0.15, zinc 0.2-1.0, beryllium 0.0002-0.001, copper 0.05-0.15, nickel 0.01-0.05, at least one element chosen from the group including the following: calcium 0.001-0.05, cerium 0.0005-0.001, inevitable impurities of silica of less than 0.1 and iron less than 0.15, aluminium- the rest.

EFFECT: high strength properties of alloy, high corrosion resistance of deformed semi-finished products made from it.
