    Product Attribute

    LEC magnetics has available multipole bonded neodymium ring magnets.


    For a more flexible alternative to sintered neodymium, consider using bonded neodymium magnets for your application. Bonded neodymium powder is used to create these magnets. Powder is melted and mixed with a polymer. Components are then pressed or extruded to create the product. Bonded Neodymium magnets  can be magnetized into complex patterns with multiple poles. Though much weaker than Sintered Neodymium magnets, Bonded neodymium magnets give greater  flexibility in terms of shapes that can be made. They are also lighter than Samarium Cobalt, and have a lower acceptable temperature (coercivity). Nevertheless, they offer excellent value for applications that require a smaller magnet or utilize radial rings. Bonded Neo Ring Magnet


    Applications include automotive, home, power tools, as well as electronic industries.


    Traditionally, multi-pole sintered Neo ring magnets were created using multiple arc magnets glued to the assembly. While spinning, it was not uncommon for the adhesive material to loosen and the magnet would dislodge itself. Also, the requirements for accuracy between all of the magnets in the ring shape required the exact same physical and magnetic properties - thus many magnets would fail because of the lack of homogeneity
