Abstract
This paper describes the complete manufacturing process for production of the aluminium foam with its achieved important physical properties and its uses in various industries. The production process of aluminum metallic foam includes high purity molten aluminium in which a small amount of calcium carbonate powder is continuously faded and stirred thoroughly. The decomposition of calcium carbonate release gases, which are entrapped in high viscous mixture of the molten aluminium and calcium residues and create low density porous aluminium foam as shown in figure no. 7 and figure no. 8. The aluminum foam is collected and cooled in the mold. Afterward foam is removed from the mold and cut to the desired sizes. The foam with low density 848 kg/m3 is obtained and density of which is 0.342 times of pure aluminum.
