Abstract: Aluminum foams have been considered recently as one of the most promising popular materials. This due to their properties such as low density with high stiffness. Automobiles, railways, aerospace, shipbuilding, household applications and other, they all can use aluminum foams. Despite the unique features of aluminum foams but they still limited in using because of their expensive fabrication costs. However, this study introduced the recycling of aerosol aluminum cans to reduce the manufacturing cost of metallic foams with using dolomite as a foaming agent while it discussed the effects of the grain size for dolomite (CaMg (CO3)2) on physical properties of the manufactured aluminum alloy. The foams were produced with a different grain size of dolomite (90, 125, 150 and 180 μm) as a foaming agent. Foam density and porosity resulted was calculated using (mass-volume direct method). Relative density resulted was in the range of 0.21-0.33 with 10-23 pores per inch for the produced Al alloy closed cell foam. While the energy absorbed by fabricated foams was in range (0.5- 0.42 MJ/m3).
