摘要： An Fe-based amorphous alloy of the present invention has a composition formula represented by Fe100-a-b-c-x-y-z-tNiaSnbCrcPxCyBzSit, and in the formula, 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. Accordingly, an Fe-based amorphous alloy used for a powder core and/or a coil encapsulated powder core having a low glass transition temperature (Tg), a high conversion vitrification temperature (Tg/Tm), and excellent magnetization and corrosion resistance can be manufactured.
