FIELD: metallurgy. SUBSTANCE: invention refers to manufacture of foil, ingots and shaped castings from aluminium and its alloys. Hardener bar consists of metal jacket and filling agent. Metal jacket is made from aluminium-titanium- boron alloy and filling agent is composed of mixture of salts selected from series cryolite-sodium chloride-potassium chloride-sodium fluoride with proportion of mass of jacket and mass of filling agent kept within limits from 1:0.2 to 1:0.6. EFFECT: increased quality of aluminium foil and semifinished items from deformed alloys. 2 cl, 2 tbl
