1J50 is a kind of soft magnetic alloy. Soft magnetic alloy is easily magnetized under the action of external magnetic field, and the magnetic induction intensity disappears after the magnetic field is removed. Soft magnetic alloy is divided into low carbon electrical steel and Amco iron, silicon steel sheet, ferronickel soft magnetic alloy, iron cobalt soft magnetic alloy, Sendust aluminum soft magnetic alloy, soft magnetic alloy in the power industry, mainly used in the more High magnetic field with high magnetic induction and low core loss of the alloy. In the electronics industry, alloys with high permeability and low coercivity at low or medium magnetic fields are mainly used. At high frequencies, thin strips or alloys of higher resistivity must be used. Generally use plate or strip.
