FIELD : metallurgy. SUBSTANCE : aluminium composite material reacting with water for production of a film onto a base contains an initial aluminium material with purity of 4N or 5N, bismuth introduced in it in the amount in the range from 0.8 to 1.4 wt % and silicon, including silicon in the form of an admixture to the initial aluminium material, in the total amount in the range from 0.25 to 0.7 wt % in terms of the aluminium weight. Bismuth and silicon are evenly dispersed in a composite material with provision of composition homogeneity. EFFECT : produced film of a composite material provides for the possibility of extracting precious and rare metals with preservation of their high quality. 5 cl, 3 dwg, 2 ex
