Porous aluminum is a multifunctional material with very lightweight and high energy absorptivity. In this study, the applicability of friction stir processing (FSP) route precursor method to the manufacture of near-net-shape porous aluminum component was discussed. Precursors fabricated by FSP route were foamed in a rectangular shape die, and it was shown that rectangular near-net-shape porous aluminum with a porosity of approximately 70% can be successfully manufactured under suitable foaming condition. The pore structure of near-net-shape porous aluminum was similar to those in commercially available porous aluminum.
