Bonded Neodymium Magnets are the perfect choice for high performance applications. Manufactured from a NdFeB alloy powder, these magnets can be used for a wide range of motors, such as spinder motors, stepping motors, synchronous motors, DC motors and brushless motors. With a maximum operating temperature of 120°C-150°C, they can be used in a wide range of temperature environments. The magnets are available in a variety of shapes and sizes, with a minimum order quantity of 100 pieces, and packaging options of carton boxes and pallets.
Bonded Neodymium Magnets are especially suitable for applications that require high levels of performance and robustness. They offer excellent magnetic properties, with a high level of magnetic strength and energy product, and are capable of delivering high performance even in the most testing conditions. The magnets are designed to be resistant to corrosion and abrasion, allowing them to retain their performance over time. The neodymium rings with 8 poles also offer superior performance and can be used in a range of applications.
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
