Embodiment 1
[0146] First, 2% Ni-Fe alloy powder (manufactured by EPSON ATMIX Co., Ltd., with a true density of 7.827 g / cm3) with an average particle diameter of 6 μm produced by a water spray method was prepared. 3 ) as raw material powder. In addition, the composition of the 2% Ni-Fe alloy is: C: 0.4% by weight to 0.6% by weight, Si: 0.35% by weight or less, Mn: 0.8% by weight or less, P: 0.03% by weight or less, S: 0.045% by weight or less, Ni: 1.5% by weight to 2.5% by weight, Cr: 0.2% by weight or less, Fe: the remainder.
[0147] On the other hand, as an organic binder, polyvinyl alcohol (Kuraray Co., Ltd. RS-1717), glycerin (Wako Pure Chemical Industries, Ltd.), and an alkylamine derivative (acetate) were prepared. In addition, ion-exchanged water was prepared as a solvent. The amount of solvent added was 50 g of solvent per 1 g of organic binder. Furthermore, the degree of saponification of polyvinyl alcohol was 93, and the degree of polymerization was 1700.
