PCT: 130°C, humidity 100%, vapor pressure 2.7 bar,
20 days, average low weight loss <2 mg/cm2.
4. DEMAGNETIZATION CURVE
5.APPLICATION
The sintered neodymium-iron-boron (NdFeB) permanent magnet is widely used in
permanent magnet servo motor, permanent magnet elevator tractor, wind driven generator,
permanent magnet linear motor, permanent magnet step motor, permanent magnet micromotor,
permanent magnet oil field motor, permanent magnet transducer, permanent magnet loudspeaker,
electronic component, medical equipment and so on.
Magnetization Direction
Common direction of magnetization showed in picture bellow:
1> Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
2> Rectangle shape magnets can be magnetized through Thickness, Length or Width.
3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness.
Special direction of magnetization can be customized as required.
