Abstract

Porous (foamed) Al alloy mouldings, contg. an additive elements 0.3-5 (1.5-2.5) wt. % Mg, of which the apparent volume is 0.5-2.7 g/cc, have their porosity created by a conc. of H2 of 0.5-5.0 (1-3) cc/100 g, the partial pressure of H2 in the bubbles being somewhat below atmospheric which the mouldings contain 1000-5000 (2000-3000) ppm (by wt.) of O2. The matl. has a high energy absorption capacity, achieved in curshing while its thermal conductivity is markedly less than that of the metal in mass. The method does not involve use of metallic hydrides and other thermally decomposable cpds. The foam does not form till the moment of casting so that no worker is pressed for time during prepn. by the need to avoid untoward decompsn., etc. The prods. are used for building facade panels.
