4> Outstanding Product.
1> High performance: N54 N52M N50H 46SH 42UH 38EH 33AH etc
2>High Working Temperture:The AH series with 40KOE super-high coercive force can replace Smco magnets in most applications
3>High Consistency
The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67.
The Consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%.
4>High Anti-Corrosion
The salt spray test and humidity heat test of the high
anti-corrosion coating Nickel+Copper+Epoxy is typically more than 500 hours.
5.Low Weight Loss
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.
