    Bonded NdFeB Magnets


    Description

    Bonded NdFeB Magnets

    China Rare Earth Magnet Limited supply bonded NdFeB magnets in grades BNP-2BNP-4BNP-6, BNP-8L, BNP-8, BNP-8SR, BNP-8H, BNP-9, BNP-10, BNP-11, BNP-11L, BNP-12, which can be coated with back or grey epoxy. Bonded neodymium magnetic materials are characterized by their high flexibility of magnetization direction and shapes. It can be magnetized into radial multi-poles through diameter or axle, and be manufactured into a variety of complex shapes. The magnetic performance of bonded NdFeB material is highly consistent, the volatility of which can be within 5%. Therefore, bonded neodymium iron boron magnets are most commonly applied in office automation equipment, electrical machinery, audio-visual equipment, precise instruments and meters, small motors and measuring machinery, and do on. With the growing trend of miniaturization and microminiaturization of electronic components, the application of bonded permanent magnets will expand continually.
