Sintered Rare Earth NdFeB Magnet: is one of the high performance rare earth permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as their main ingredients.

1. The NdFeB magnet has high remanence, high coercive force, high energy product and high ratio between   performance value and product cost.

2. It can be easily formed into various sizes.

3. Smaller size and lighter weight in designing devices

4. Grade: N35-N52, 33M-50M, 30H-48H, 30SH-45SH, 30UH-40UH, 28EH-38EH, 30AH-33AH.

5.High energy range from 30MGOe to 53MGOe with wonderful coercive force

6. For most applications, coating or plating is recommended.

7. Coatings: Ni, Zn, gold, copper, epoxy, chemical, parylene and so on.

8. Advantages:
     a) High energy 
     b) Very high Hc and Hci output
     c) More economical than SmCo
     d) Wonderful performance at ambient temperature

9. Disadvantages:
     a) Working temperature is below 220°C.
     b) Prone to oxidation than other magnet alloys

10. Applications: Widly used in industrial areas and Micro products, such as Motor, sensors,  loudspeaker, windmill, Auto, National defence, Speaker, Computer, Biology project, Medical treatment, Instrument and Meter etc.
