The invention discloses an iron-based amorphous alloy material, an iron core adopting the iron-based amorphous alloy material, a preparation method of the iron core and a current transformer comprising the iron core. The iron-based amorphous alloy material is prepared from the following components in parts by mass: 81.1 to 81.4 parts of iron, 8.8 to 9.1 parts of silicon, 6.3 to 6.5 parts of niobium, 1.9 to 2.1 parts of boron and 1 to 1.3 parts of copper. The iron-based amorphous alloy material disclosed by the invention is an amorphous material formed by taking Fe as a main element, doping a small amount of Nb, Cu, Si and B elements, and carrying out processes of melting, amorphization, nanocrystallization and the like. In combination with a specific embodiment, the initial magnetic conductivity of the iron-based amorphous alloy material disclosed by the invention is obviously higher than that of a traditional material; the problems that a traditional iron core is out of tolerance in the case of small ampere
