Bonded Neodymium Magnet is a high-performance magnet made from neodymium bonded with other metal alloys. It is a versatile and cost-effective solution for a variety of applications requiring high magnetic force. Bonded Neodymium Magnet is available in five grades: BN-4, BN-6, BN-8, BN-10, and BN-12L, all made with NdFeB alloy powder. It can be magnetized in three directions: axial, radial, or multi-poles, and can withstand temperatures up to 150°C. Bonded Neodymium Magnets are commonly used in various motors, including spinder motors, stepping motors, synchronous motors, DC motors, and brushless motors. As a reliable and cost-effective alternative to traditional rare-earth magnets, Bonded Neodymium Magnets are an ideal choice for applications requiring superior magnetic performance.
Advantages
Compression Bonded:
Higher Magnetic Strength due to higher magnetic particle density.
Epoxy Binder / Resistant to normal industrial solvents and
automotive fluids
Epoxy Coat after manufacturing to prevent oxidation
Temperature Range -40c – 180c
“Tight” tolerances off tool
Good mechanical strength
Disadvantages
Requires tooling and mold costs
Piece price will be low only in high volume
Low magnetic properties
