Porous aluminum samples were manufactured by powder metallurgy method. In the powder metallurgy method, pure Al 99 % powder (< 44μm) and TiH2 powder of two different sizes (< 44 μm and 1-3 μm) were mixed at different volume fractions. All the porous samples were subjected to a compression test and characterized by electrical conductivity, hardness and specific heat capacity measurements according to the porosity observed by image analysis. It was determined that compression strength is decreased by the percentage of total pore area in the section. The specific heat capacity values of the porous material are increased slowly by TiH2 size, pore number and pore area. The electrical conductivity of the porous material has a decreasing trend dependent on the percentage of TiH2.
