Abstract

PURPOSE: To obtain an Fe-Si sintered alloy having magnetic properties equal to or better than those of Fe-Si ingot alloy, by mixing a Si-containing iron alloy powder containing Si in the range of specified contents with a Si-containing iron alloy powder having a melting point higher than the former, and sintering the mixture so that the product has specified amounts of Si.
CONSTITUTION: An iron alloy powder containing 46W72% of Si and/or iron alloy containing 13W24% of Si that will become a liqud phase at 1,300°C or below is mixed with a Si-containing iron alloy powder having a melting temperature 1,300°C or above and excellent in the direct current magnetic properties. After the mixed alloy powder is sintered at 1,300°C or below, it is sintered in the liquid phase while the amount of Si is adjusted in the range of 1W10%, so that a high density Fe-Si sintered alloy can be obtained. The density of the obtained sintered alloy is higher and excellent in the direct current magnetic properties as compared with a sintered alloy of a single kind of powder and having the same amount of Si.
