In this study, gradient porous Al-Cu sintered body was fabricated by powder metallurgy processing. Al-Cu powder mixtures were prepared by low energy ball milling with various milling time. After ball milling for 3h, the shape of powder mixtures changed to spherical type with size of 100~500 . Subsequently, Al-Cu powder mixtures were classified (under 150, 150~300 and over 300 ) and compacted (20, 50 and 100 MPa). Then, they were sintered at for various holding time (10, 30, 60 and 120 min) in atmosphere. The sintered bodies had 32~45% of porosity. As a result, the optimum holding time was determined to be 60 min at and sintered bodies with various porosity were obtained by controlling the compacting pressure.
