Soft Ingot Iron Disk

Soft Ingot Iron Disk retains the high permeability, low coercivity, and ductility of the coil form but is precision-machined into a circular profile, making it suitable for rotational magnetic components, magnetic couplings, and experimental test fixtures. Its soft magnetic behavior ensures minimal energy loss in alternating magnetic fields, supporting use in generator rotors, magnetic clutches, and precision magnetic measurement devices. Specific applications include laboratory electromagnet pole faces, rotating magnetic field experiments, and high-efficiency magnetic coupling disks in pump drives. In research, these disks are utilized for studying flux distribution, developing advanced magnetic alloys, and creating model systems for motor and generator prototypes. The disk format’s consistent geometry and machinability make it a dependable choice for precision magnetic engineering and materials science studies.
