Neodymium Magnets

Feb. 14, 2020

NdFeB permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. Compared with cast Al-Ni-Co series permanent magnet materials and ferrite permanent magnet materials, neodymium-iron-boron has a very high magnetic energy product and coercive force, and can lift a weight equivalent to 640 times its own weight. The advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology. Rod Neodymium Magnets Manufacturer will give you a detailed introduction below.


Nd-Fe-B permanent magnet is a kind of Nd-Fe-B magnetic material, which is also called the latest result of the development of rare earth permanent magnet materials. It is called "Magnetic King" because of its excellent magnetic properties. This is a product developed by the National 863 High-Tech Plan. NdFeB permanent magnets have extremely high magnetic energy product and corrective force. At the same time, the advantages of high energy density have made NdFeB permanent magnet materials widely used in modern industry, electronic technology and medical industry. Acoustic motors, magnetic separation magnetization, medical equipment, medical equipment and other equipment can be made smaller, lighter and thinner. The advantages of NdFeB permanent magnets are high cost performance and good mechanical properties. The disadvantages are that the curie temperature point is low, the temperature characteristics are poor, and it is easy to pulverize and corrode. It must be adjusted by its chemical composition and surface treatment. It can be improved to meet the requirements of practical applications.


NdFeB permanent magnets are divided into two types: sintered NdFeB and bonded NdFeB. The bonded NdFeB is magnetic in all directions and resistant to corrosion; while sintered NdFeB is easy to corrode, it needs to be coated on the surface. Zinc, nickel, environmentally friendly zinc, environmentally friendly nickel, nickel copper nickel, environmentally friendly nickel copper nickel, etc. Sintered NdFeB is generally divided into axial magnetization and radial magnetization, depending on the required working surface. Depending on the shape, Segment Neodymium Magnet can be used.

General applications of NdFeB permanent magnets

NdFeB permanent magnets have excellent magnetic properties and are widely used in electronics, electric machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, and computer disks. Drivers, magnetic resonance imaging equipment, etc.


Medical applications of NdFeB permanent magnets

NdFeB permanent magnet is a high-tech material of the National 863 Project. What he can produce is a biological magnetic field that simulates the characteristics of the human magnetic field, with stable performance! Acting on the human body can correct the magnetic field of the human body, and by enhancing the biological electromagnetic energy of the human meridian, massaging many acupoints of the human body, and promoting the operation of meridian air, so as to achieve meridian activation, increase brain blood supply and oxygen, and promote hair follicle regeneration. Reduces the excitability of peripheral nerves in the cerebral cortex, and has the effects of promoting bone and joint tissue metabolism, hypnosis, analgesia, sedation, activating blood and eliminating anxiety. At present, it is commonly used in the domestic medical industry to treat chronic bone and joint diseases such as hair loss, insomnia, neurasthenia, cervical spondylosis, periarthritis, lumbar muscle strain, and lumbar disc herniation.


The above is the application of NdFeB permanent magnet introduced by the Block Neodymium Magnet supplier.
