Ndfeb Magnet(Bonded)
NdFeB Magnet(Bonded) NdFeB Magnet(Bonded)


Produced by composition of rare-earth NdFeB magnetic powders embedded in thermoplastic and formed by injection moulding machining
Hard, Non-brittle light weight; plastic-like magnet, able to be moulded to varieties of shapes e.g. thin ring, gears, arc-segments etc.; able to incorporate with shafts during manufacturing.The magnets can be made in different shapes, some of which are rather complicated.
Excellent resistance to demagnetization
Good temperature stability
Good resistance to corrosion and chips

Key application:

  • Magnetic separators
  • Microphone assemblies
  • Servo motors
  • DC motors (automotive starters) and other motors
  • Meters
  • Odometer
  • Sensor
