Basic Knowledge And Applications Of Ndfeb Magnets

Nov. 25, 2019

NdFeB magnet, it is currently the magnet with the highest commercial performance found, known as the magnetic king, has the characteristics of small size, light weight and strong magnetism, is by far the best performance-price magnet. Common is the Internal Threaded Pot Magnet of NdFeB, which has extremely high magnetic properties and its maximum magnetic energy product (BHmax) is more than 10 times higher than ferrite. Its own machinability is also quite good. The maximum operating temperature is 200 degrees Celsius. And its texture is hard, its performance is stable, and it has a very good price-performance ratio, so its application is extremely extensive. But because of its strong chemical activity, its surface coating must be treated (such as Zn, Ni plating, electrophoresis, passivation, etc.).


Basic knowledge of NdFeB magnets:


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


It is expected that in the next 20-30 years, there will be no magnetic materials that can replace NdFeB magnets. The main raw materials for the production of NdFeB magnets are metal neodymium, pure iron, ferroboron alloys 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 the third generation of rare earth permanent magnet materials, NdFeB magnets have a high performance-price 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. The development of new materials has continuously brought new uses to the rare earth permanent magnet NdFeB industry and other functional materials, which has brought a wider market prospect for the NdFeB industry.


NdFeB magnets in medical applications:


NdFeB permanent magnet is a high-tech material of the National 863 Project. What he can generate is a biological magnetic field that simulates the characteristics of the human magnetic field, with stable performance! Acting on the human body can rectify the magnetic field of the human body itself, and by promoting the biological electromagnetic energy of the human meridian, promote the operation of meridian air, so as to reach the meridian, increase the blood and oxygen supply to the brain, reduce the excitability of peripheral nerves in the cerebral cortex, and promote bone The effects of joint tissue metabolism, hypnosis, analgesia, sedation, blood circulation and anxiety elimination. At present, it is commonly used to treat chronic bone and joint diseases such as insomnia, neurasthenia, cervical spondylosis, and periarthritis, as well as the pain and numbness caused by these diseases.
