FIELD: metallurgy.
SUBSTANCE: according to the method there prepared is molten aluminium and heated above liquidus temperature. Molten metal is pored to the mould heated to the same temperature and filled with granules of water-soluble salts. At that, there used are salts which do not chemically interact with molten aluminium, with fusion temperature which is higher than heating temperature of molten metal and mould and with density which is higher than molten aluminium. After hardening the ingot is removed from the mould and placed in water.
EFFECT: enlarging the range of items made from foam aluminium, increasing quality of foam aluminium, reducing production cost of foam aluminium.
