iron-boron-silicon

Iron-boron-silicon alloys are a type of magnetic alloy that combine iron with boron and silicon. These alloys are known for their magnetic properties, particularly their high permeability and low core loss, making them suitable for applications in transformers and other electrical equipment. The addition of silicon to iron, for instance, reduces magnetocrystalline anisotropy and hysteresis loss, while increasing electrical resistivity, which helps minimize energy loss from eddy currents. Boron can also be added to iron-based alloys to modify their magnetic characteristics. These alloys are distinct from Alnico alloys, which are primarily composed of aluminum, nickel, and cobalt and are used for permanent magnets.123
