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)
