Magnesium metal foams have the ability to withstand the structural material impact for the lightweight applications. However, the main disadvantages of using magnesium are due to high reactivity and consequently the mechanical characteristics. The present study aims at evaluating the effect of porosity on the mechanical characteristics. The magnesium metal foams are fabricated by powder metallurgy technique using the crucible made of silica gel for holding the particles. The magnesium powder of 350 microns of mesh size was used as raw material. The mechanical behaviors were evaluated by the universal testing machine. Foams with 36%- 43% porosity have the compression strength of 17.134MPa - 85.032 MPa.
