Sintered material in the past study couldn't be applied to higher-output Power tools because the shortage strength. In this study we developed higher-strength sintered material, and applied to higher-output Power tools. There is a correlation between strength and density. Therefore from the side of the element of powder alloy and the technique of compacting gear this study was proceeded. By investigation from the both side, the newly developed material has achieved 0.2Mg/m^3 higher density and 30% higher strength level than the material based on the simple pre-alloy powder material.
