Document Type and Number:
Japanese Patent JP7148876
Kind Code:
B2
Abstract:
An amorphous alloy thin strip according to the present invention has an alloy composition represented by the formula: Fe100-a-b-c-dCuaSibBcSnd (wherein a, b, c and d represent values of at.% which satisfy the requirements represented by the formulae: 0.3 ≦ a < 1.55, 1 ≦ b ≦ 10, 11 ≦ c ≦ 17, 0.25 < d ≦ 1.0, and a+d ≦ 1.80). According to the amorphous alloy thin strip of the present invention, it is possible to provide: an amorphous alloy thin strip and an amorphous alloy powder each having excellent crushability and soft magnetic properties; and a method for producing a nanocrystalline alloy dust core using either one of the amorphous alloy thin strip or the amorphous alloy powder.
