Porous aluminum has good lightweight property, high specific strength and high energy absorption ability. By applying porous aluminum as a multifunctional material of automobile, both collision safety and improvement of fuel efficiency can be realized. As the new fabrication method of porous aluminum of having high productivity and low-cost productivity, authors proposed the method by utilizing friction stir processing, i.e. Friction stir processing method (FSP method). In this study, changing the amount of alumina addition, holding temperature and holding time, porous aluminum is fabricated by FSP method. Based on the experimental results, the effects of these fabricating conditions on the porosity and the morphology of pores are investigated. It is shown that porous aluminum with the porosity up to 80% can be realized by optimizing the alumina addition, holding temperature and holding time.
