Product Description

These bonded neodymium magnets achieve high dimensional accuracy and complex shaping through a unique manufacturing process that combines plastics with Nd-Fe-B metal powder. While offering slightly lower magnetic strength than sintered neodymium magnets, they provide superior dimensional precision and can be formed into thin or complex shapes.

Key Features
  • Compression bonded for higher magnetic strength
  • Epoxy binder resistant to industrial solvents and automotive fluids
  • Protective epoxy coating prevents oxidation
  • Wide operating temperature range (-40°C to 180°C)
  • Excellent mechanical strength and tight tolerances
  • Available in multiple grades (BN-6, BN-8, BN-10, etc.)
  • Customizable magnetization (axial, radial, or multi-pole)
