ALUMINUM-BASED ALLOY AND PRODUCT MANUFACTURED THEREFROM Russian patent published in 2002 - IPC

FIELD: alloys as structural materials. SUBSTANCE: invention relates to thermally non- strengthened, weldable, deformable aluminum/magnesium/scandium/zirconium alloys used as structural materials for special-destination products long working within temperature range between +85 C and -196 C, such as boarding, fittings, conditioning-system parts, covers, and so on. Alloy gas following analysis, wt.%: magnesium, 4.8-7.0; zirconium, 0.08-0.20; scandium, 0.1-0.30; beryllium, 0.0002-0.005; manganese, 0.2-0.5; titanium, 0.01-0.07; iron, 0.05-0.30; and at least one mineral from the group containing cobalt, 0.01-0.25; nickel, 0.01-0.25; and aluminum, the balance. EFFECT: improved mechanic characteristics of alloy at room and cryogenic temperatures, improved properties of welded joints, and enabled utilization of superplastic molding. 2 cl, 2 tbl
