NdFeB Ring Magnet

The NdFeB Ring Magnet is the ultimate expression of modern material science, utilizing the powerful Neodymium-Iron-Boron chemical composition.8 These magnets are the strongest permanent magnets available on the market today, offering a high resistance to demagnetization (Hcj). The ring shape is meticulously formed to balance the magnetic “pull” force with the mechanical requirements of modern industrial hardware, providing a high-energy potential in a lightweight package.

NdFeB is a brittle material, so BMAG ring magnets are designed with micro-chamfered edges to dissipate mechanical stress.11 We offer a variety of surface treatments beyond standard Nickel, including Zinc (Zn) for cost-effectiveness, or Epoxy for superior salt-spray resistance. The sintering process ensures a dense, non-porous structure that maximizes the $B \times H$ product. Every NdFeB ring is checked for magnetic flux leakage to ensure that the energy is concentrated exactly where your design requires it. These magnets are an essential upgrade for any system currently using bulky ferrite or AlNiCo rings.
