The Main Application of NdFeB Magnet

Dec. 29, 2020

Neodymium Iron Boron Magnets, which are currently the most commercially available magnets, are known as Magneto. They have the characteristics of small size, light weight and strong magnetism, and are the magnets with the best performance-to-price ratio so far. With extremely high magnetic properties, its maximum magnetic energy product is more than 10 times higher than that of ferrite. Its own machining performance is also quite good. The operating temperature can reach up to 200 degrees Celsius. Moreover, its hard texture, stable performance, and good cost performance, so its application is extremely wide. But because of its strong chemical activity, it must be coated on the surface. .

Basic knowledge of NdFeB magnets

NdFeB magnets can be divided into two types: bonded NdFeB and sintered NdFeB. 


It is estimated that in the next 20-30 years, it is impossible to replace NdFeB magnets with magnetic materials. The main raw materials for the production of NdFeB magnets are metal neodymium, pure iron, boron-iron alloy and other additives.

The core technology of the NdFeB magnet industry is mainly reflected in the manufacturing process, which is specifically reflected in the uniformity, consistency, processing quality, and coating quality of its products.

As a third-generation Rare Earth Magnet material, NdFeB magnets have a high cost performance ratio. They are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the knowledge economy represented by information technology. Development has continuously brought new applications to the rare earth permanent magnet NdFeB industry and other functional materials, which brings a broader market prospect for the NdFeB industry.

NdFeB magnets in medical applications:

NdFeB permanent magnets are high-tech materials for the National 863 Project. What he can generate is a biomagnetic field that simulates the characteristics of the human body's magnetic field, with stable performance! Acting on the human body can correct the human body’s own magnetic field, and by enhancing the bio-electromagnetic energy of the human body’s meridians, promote the movement of the meridians, so as to achieve the passage of the meridians, increase the brain’s blood supply and oxygen, reduce the excitability of the peripheral nerves of the cerebral cortex, and promote bone The effect of joint tissue metabolism, hypnosis, analgesia, sedation, blood circulation and anxiety elimination. At present, it is commonly used to treat chronic diseases of bones and joints such as insomnia, neurasthenia, cervical spondylosis, frozen shoulder, and the symptoms such as pain and numbness caused by these diseases.

The application range of NdFeB magnets is as follows:

Electroacoustic field: speakers, receivers, microphones, alarms, stage audio, car audio, etc. 


Electronic appliances: permanent magnet mechanism vacuum circuit breaker, magnetic holding relay, watt-hour meter, water meter, sound meter, reed switch, sensor, etc.


Motor field: VCM, CDDVD-ROM, generators, motors, servo motors, micro motors, motors, vibration motors, etc.


Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc. 


Medical and health care: nuclear magnetic resonance instrument, medical equipment, magnetic health care products, magnetized fuel economizer, etc.  

Other industries: magnetized anti-wax device, pipe descaler, magnetic fixture, automatic mahjong machine, magnetic locks, door and window magnetism, luggage magnetism, leather magnetism, toy magnetism, tool magnetism, craft gift packaging, etc.
