    Product Description

    Product Attribute

    LEC magnetics has available isotropic bonded neodymium ring magnets.


    Multipoles Bonded Ring Magnets in grade BNP-2,BNP-4,BNP-6, BNP-8L, BNP-8, -8SR, BNP-8H, BNP-9, BNP-10, BNP-11, BNP-11L, BNP-12, which can be coated with back or grey epoxy. Most customers usually require ring magnets made bonded NdFeB material with multi-poles through diameter or radial magnetization. We also customize bonded magnets in arc, block shapes, etc.


    Bonded NdFeB VS Sintered NdFeB Magnets

    Compared with sintered neodymium permanent magnet material, bonded NdFeB magnet material can be pressured directly to precise dimensional magnets without sintering process and secondary operation, and they can make all kinds of complicated shaped magnets.


    Bonded magnet is one of the most important magnetic materials. It opened a new world of application possibilities. Thermo-elastomer and thermo-plastic resins can be blended together with a variety of magnetic powders to form injection molded, compression and flexible magnets.


    Bonded NdFeB VS Isotropic Ferrite Magnet

    The emergence of bonded NdFeB material gets rid of the bondage of the low performance isotropic ferrite magnets, promoting and accelerating the design and development of high performance multi poles motors. While all this depends on multi-poles magnetization technique and multi-poles bonded NdFeB ring magnets with magnetization through diameter or axially thickness. Common permanent magnets with multi poles magnetizations are 4 poles, 6 poles, 8 poles or more which depend on the dimensions and the application of the magnets. neodymium bonded radial ring magnet, ring compression bonded magnet, bonding ndfeb ring magnet, compression molded ring magnet.


    Applications of Bonded NdFeB magnets

    • Drive and generator applications

    • Miniaturized sensors

    • IT industry

    • Meters and instruments

    • Home electronics
