FIELD: metallurgy.
SUBSTANCE: invention relates to the aluminium-based deformable alloys intended for use in braze structures. An aluminium-based deformable alloy for braze structures contains, wt %: zinc 3.4-5.0, magnesium 1.0-2.5, manganese 0.2-0.9, chrome 0.1-1.0, zirconium 0.1-1.0, copper up to 0.5, beryllium 0.0001-0.01, hafnium - 0.1-1.5, titanium 0.1-1.0, vanadium - 0.1-1.0, aluminium - the rest. The tendency to recrystallisation decreases and the fine-grained structure remains after processing in the brazing mode at the temperature close to solidus.
EFFECT: high characteristics of mechanical properties and corrosion resistance of brazing connections are provided.
