Herein, the effect of various treatment modes on the magnetic properties of amorphous alloys Fe49Ni29Si9B13 and Fe59Ni19Si9B13 obtained by melt spinning was considered. Samples from both alloys were heat-treated separately in the magnetic field and without the field. An increase in soft magnetic properties was detected during the transition to the crystalline phase (Hc = 0.63Oe, Bm = 1.55T, Br = 2.16T). It was determined that the soft magnetic properties of materials disappear with the formation of crystalline phases. The obtained materials were applied by replacing the electrical steel in the core of the LC1E2501 contactor produced by Schneider. During the operation, the result was 7% higher than the plant resource.
