A bonded magnet, a composite material blending magnetic powder within a binder matrix, excels in performance consistency, complex shapes, and high dimensional accuracy. It requires no secondary machining, integrates seamlessly with functional components, and suits mass production. The magnetic powder, volume fraction of binder, and internal porosity critically shape a bonded magnet’s magnetic and mechanical properties, enabling a bonded magnet to meet diverse industrial demands with precision and reliability.
Isotropic Neodymium magnets lead the bonded rare earth magnet market, capturing over 80% share, while anisotropic Neodymium, SmFeN, anisotropic Samarium Cobalt, and hybrid magnets share the rest. Beyond varied magnetic powders, a bonded magnet employs thermosetting or thermoplastic binders, supporting processes like compression, injection, extrusion, and calendering molding, offering flexibility for applications in electronics, automotive, and more.
