As formed, these magnets achieve high dimensional accuracy and complex shaping.
These magnets are made by combining plastics with metal powder having a combination (Nd-Fe-B) similar to that of sintered neodymium magnets and then forming the mixture. Since the magnets contain plastics, the magnetism is much lower. As formed, however, these magnets offer the advantage of being processed into thin products with high dimensional precision and products of complex shaping. Moreover, isotropic magnets are easily magnetized radially and can be magnetized in many varieties as well. Their temperature characteristics are a little lower than those of neodymium magnets, and are unsuited for use at 80°C or higher.
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
