  The releasing force of ADC10 die castings was measured using ejector pin type pressure sensor and the microstructure was observed in order to investigate the effect of Fe and Mn on the releasing ability. Inverse segregation with concentration of Fe, Mn and Si a two or three time higher than the average composition of Fe, Mn and Si was observed. Intermetallic compounds of Al<sub>5</sub>FeSi were observed at the surface of die casting added with 0.8 mass % Fe. Granular intermetallic compounds of Al<sub>15</sub> (Fe, Mn)<sub>3</sub> Si were observed at the die castings surface added with 0.8 mass % Fe and 0.4 mass % Mn. The hardness of the casting surface layer was increased by the inverse segregation of the intermetallic compounds. The releasing force of die castings without Fe and Mn increased with increasing of casting amount increased. The releasing force of the die castings which contain 0.8 mass % Fe and / or 0.4 mass % Mn did not increase.
