FIELD: metallurgy. ^ SUBSTANCE: invention concerns metallurgy field. Particularly it concerns alloys on aluminium basis and can be used in general engineering and other fields of industry. Alloy and product made on it basis contain following ratio of components, wt %: zinc 4.4-9.0, magnesium 0.5-3.5, copper 0.01-1.2, iron till 0.35, silicon till 0.25, nickel till 0.1 and/or cobalt till 0.1, chrome till 0.35, vanadium till 0.15, titanium till 0.15, boron till 0.03, calcium till 0.05 at least one element from group: manganese till 0.8, zirconium till 0.25, scandium till 0.25, hafnium till 0.25, aluminum - the rest, at that ratio Mg/Cu is more or equal to 1.8. Rising of flexibility and weldability of alloys on aluminium basis and also strength and flexibility of welded joint what increases useful life and reliability of product operation, extends its range. ^ EFFECT: fortification and flexibility increasing of welded joint. ^ 2 cl, 2 tbl, 1 ex |
