The price difference between Bonded NdFeB and sintered NdFeB is large (about 10 times), bonded is much more cheaper, one reason is less material and less process, the main reason is process of sintered NdFeB.The sintered technology is mainly controlled by Japanese companies, with same material some of our Chinese company can not make high-performance NdFeB as Japanese company, we can only purchase products at high prices from Japan.
But we had completely mastered bonded NdFeB simple process, so Japan can only be discontinued, can not compete with China in bonded NdFeB because of the cheap price we offered.
Sintered NdFeB powder is sintered anisotropic magnets produced by the method. Usually after sintering can produce rough, then after machining (such as wire cutting, slicing, grinding, etc.) in order to become a magnet of various shapes. Sintered NdFeB are difficult machining brittle materials, process loss, high cost, relatively poor dimensional accuracy, corrosion resistance is poor, the surface needs to plating. But the advantage of high performance, has done more than 50M.Bonded NdFeB magnets market despite a late start, but the market is growing rapidly. With respect to the sintered NdFeB magnet, bonded NdFeB magnets on the dimensional accuracy and stability of the production costs have obvious advantages, along with the miniaturization of electronic devices, miniaturization trend of development, will continue to expand its application areas. Steady growth in market demand, lifting huge magnet pink patent imagination. Hard disk drive market growth is stable, automotive micro-motor market and mobile phone vibration motor market penetration continues to improve, to ensure the rapid growth of bonded NdFeB magnets market demand; MQ Magnetic patent expiration and anisotropic bonded NdFeB magnets and other emerging new technologies for the future development of bonded NdFeB magnets laid a reliable foundation.
