Abstract
An Fe-based amorphous alloy powder of the present invention has a composition represented by (FeNiSnCrPCBSi)M. In this composition, 0 at %≦a≦10 at %, 0 at %≦b≦3 at %, 0 at %≦c≦6 at %, 6.8 at %≦x≦10.8 at %, 2.2 at %≦y≦9.8 at %, 0 at %≦z≦4.2 at %, and 0 at %≦t≦3.9 at % hold, a metal element M is at least one selected from the group consisting of Ti, Al, Mn, Zr, Hf, V, Nb, Ta, Mo, and W, and the addition amount α of the metal element M satisfies 0.04 wt %≦α≦0.6 wt %. Accordingly, besides a decrease of a glass transition temperature (Tg), an excellent corrosion resistance and high magnetic characteristics can be obtained.
