Permanent magnetic ferrite for high-strength magnetic steel

High strength magnetic steel mainly consists of barium ferrite and strontium ferrite. High strength magnetic steel has high resistivity and coercivity. It can be effectively applied to the air gap magnetic circuit, especially suitable for small generators and permanent magnets of motors. Permanent magnet ferrite does not contain precious metals such as nickel and cobalt. Rich source of raw materials, simple process, and low cost. It can replace aluminum nickel cobalt permanent magnets in the manufacturing of magnetic separators, magnetic bearings, loudspeakers, microwave devices, etc. But high-strength magnetic steel has a large magnetic energy product, low temperature stability, brittle texture, and is not resistant to impact and vibration. It is not suitable for measuring instruments and magnetic devices with precise requirements.
High strength magnetic steel uses permanent magnetic ferrite, which is an advanced magnetic material. The characteristics of permanent magnet ferrite are high magnetization, high permeability, and low magnetic signal-to-noise ratio, which are widely used in fields such as magnetic recording, magnetic sensors, motors, and electromagnets.
Permanent magnet ferrite has high magnetic permeability and can generate high magnetic flux density under extremely weak magnetic fields, thereby improving the performance of magnetic sensors and motors, and reducing volume and weight. In terms of electromagnets, permanent magnet ferrite materials greatly improve the suction and acceleration capabilities of electromagnets, and have very important application prospects.
In addition, permanent magnet ferrite is also widely used in medical devices and production equipment. For example, in the medical field, permanent magnet ferrite is used to repair and nail bone defects and wounds; In the field of production equipment, permanent magnet ferrite is used to process high-density precision instruments and electronic equipment.
In short, permanent magnet ferrite, as an advanced magnetic material, has a wide range of applications and broad prospects for future development. We should actively embrace technological progress, further develop and use permanent magnet ferrite, and contribute to the development and progress of various industries.
