Sintered NdFeB and Bonded NdFeB price and performance differences

Sintered NdFeB and Bonded NdFeB big price difference (about 10 times), bonding a lot cheaper, one is less material, fewer steps, the key lies in the ability of poor workmanship sintered NdFeB, technology is mainly Japan lies in the hands of the same material, but we can not make high performance NdFeB, can only buy products at high prices from the hands of Japan, and we have no use materials, and bonded NdFeB simple process, we has fully mastered, so the Japanese can only be shut down, unable to compete with China in this area is the reason.

    Sintered NdFeB sintered powder is produced by anisotropic magnet. Usually only produce sintered blank and then machined (such as wire cutting, slicing, grinding, etc.) in order to become a magnet of various shapes. NdFeB belongs difficult to process hard and 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 in dimensional accuracy, stability and production costs have obvious advantages, with the miniaturization of electronic devices, miniaturization trend of development, its applications will continue to expand. Steady growth in market demand, the lifting magnet powder patent huge imagination. Hard drive market growth is stable, automotive micro-motor market and mobile phone vibration motor market penetration continues to increase, to ensure the rapid growth of bonded NdFeB magnets market demand; MQ patent expirations and magnetic anisotropic bonded NdFeB magnets and other emerging new technologies for the future development of bonded NdFeB magnets laid a reliable foundation.
