Bonded Neodymium Magnet is an injection bonded magnet made of Neodymium Iron Boron (NdFeB) material. It is widely used in motors, such as spinder motor, stepping motor, synchronous motor, DC motor, brushless motor and more. It is available in various grades, including BN-6, BN-8, BN-10 and so on. With its excellent temperature resistance, the maximum operating temperature of Bonded Neodymium Magnet can be up to 120°C, and it is also coated with epoxy or parylene to prevent corrosion and temperature damage. Bonded Neodymium Magnet is mainly used for high speed motors, as its high magnetic force and strong stability make it ideal for such applications. With its advanced injection bonded technology, Bonded Neodymium Magnet can offer high performance in different working environments.
Advantages

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

Bonded neodymium magnets are packaged and shipped in boxes with multiple layers of protective materials such as foam and bubble wrap. The boxes are then sealed and placed in a larger box with additional padding. The magnets are also labeled with a warning label to alert handlers of the powerful nature of neodymium magnets.
When shipping, bonded neodymium magnets should be shipped by a trusted, insured shipping company. The box with the magnets should be clearly labeled with the contents. The package should also be marked as "Fragile" and "This Side Up" to ensure that it is not mishandled during transit.
