Abstract
Disclosed is an iron-based amorphous alloy FeaBbSicREd, wherein a, b, and c represent, in atomic percentages, the contents of corresponding components, respectively; 83.0≤a≤87.0, 11.0<b<15.0, 2.0≤c≤4.0, and a+b+c=100; and d is the concentration of RE in the iron-based amorphous alloy, i.e. 10 ppm≤d≤30 ppm. The iron-based amorphous alloy has a saturation magnetic induction intensity of no less than 1.63 T, and same can be used to manufacture a magnetic core material for power transformers, motors and inverters.
