The invention belongs to the technical field of magnetic metal material preparation, and discloses an iron-based amorphous alloy with high saturation magnetic induction intensity and high iron content (or high ferromagnetic element content) and a preparation method thereof. The atomic percentage of Fe in the iron-based amorphous alloy is 81-87. The preparation method is based on the alloy composition in the iron-based amorphous alloy chemical expression, the ingredients are repeatedly smelted into a master alloy using a vacuum induction melting furnace or an electric arc melting furnace, and then the master alloy or the purified alloy is melted again. Rapid cooling obtains a strip-shaped amorphous alloy strip. The iron-based amorphous alloy can be used as an amorphous alloy material, and it is also expected to take advantage of the large distance between the first and second crystallization peaks to prepare iron-based nanocrystalline soft magnetic alloy with α-Fe phase by using a nanocrystalline annealing process. The iron-based soft magnetic amorphous alloy proposed by the present invention has high saturation magnetic induction, low coercivity and better comprehensive soft magnetic properties, and has good industrial application potential.
