FeCo2Si is an iron-cobalt-silicon intermetallic compound belonging to the class of ferromagnetic metals and alloys. This material is primarily investigated for soft magnetic applications where high saturation magnetization, low coercivity, and excellent magnetic permeability are required. It is used or evaluated in electromagnetic devices, magnetic cores, and high-frequency inductive components where the combination of iron and cobalt provides enhanced magnetic properties compared to conventional iron-silicon alloys, while silicon addition improves electrical resistivity to reduce eddy current losses.
