An iron-based amorphous alloy, i.e., Fe a Si b B c P d , wherein a, b, c, and d respectively represent the atom percentages of corresponding components; 81.0≤a≤84.0, 1.0≤b≤6.0, 9.0≤c≤14.0, 0.05≤d≤3, and a+b+c+d=100. By adjusting the components and component percentages of the iron-based amorphous alloy, the obtained iron-based amorphous alloy has high saturation magnetic induction density. |
