 Ni50Cr14Si Fe-Ni alloy is a low-frequency soft magnetic material with high permeability and low coercivity in a weak magnetic field. In the early days, iron-nickel alloys were used for telephone communications, and then a heat treatment process and vacuum smelting were used to greatly improve the characteristics of the alloy. The main characteristic of  Ni50Cr14Si soft magnetic alloy is that it has high saturation magnetic induction and soft magnetic permeability, various transformers, relays, electromagnetic clutch cores that work in a medium magnetic field.
