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.Shape:Disc, Ring, Block, Segment, Cylinder, Trapezoid, Customized Design (Design proper magnets for clients specific requirements).
9.Applications: Motors, Generators,NdFeB Pot Magnet,Speakers,Sensors,Earphones and other musical instruments,Magnetic therapy devices,Magnetic Chuck,Magnetic bearings and couplings,Other magnetic applications .
10. Advantages:
