Bonded Neodymium Magnets are high-performance magnets made from neodymium bonded with other metal alloys. These versatile and cost-effective magnets provide superior magnetic force for various industrial applications. Available in five grades (BN-4 through BN-12L) made with NdFeB alloy powder, they can be magnetized in axial, radial, or multi-pole configurations and withstand temperatures up to 150°C.
- Higher magnetic strength due to compression bonding and increased particle density
- Epoxy binder provides resistance to industrial solvents and automotive fluids
- Protective epoxy coating prevents oxidation
- Wide operating temperature range (-40°C to 180°C)
- Precision tolerances directly from tooling
- Excellent mechanical strength
- Requires tooling and mold investment
- Cost-effective only in high volume production
- Lower magnetic properties compared to sintered alternatives
