The true density ratio is over 95%, and the fatigue resistance is above 300 MPa, all reaching the "world's highest level" (NTN). This technology can be used to replace mechanical components such as gears, cams and sprockets that have been previously machined into sintered alloy products. The newly developed manufacturing technology is based on the powder metallurgy method. The powder metallurgy method, after the powder material is press-formed, is fired at a temperature lower than the melting point of the material to form a sintering between the metal powders. Metal molds can be used to perform processing close to the product itself and its shape (near net shape), thus having the advantages of material loss and low energy consumption during processing. However, the powder metallurgy method tends to form minute pores inside, and has a problem of poor fatigue resistance as compared with cast products and die-cast products produced by a cutting method.
