Sintered Neodymium motor 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. Grades of Strong NdFeB Motor Magnet Arc shape:

from N33 To N54 ,from N Series to AH Series.

Magnet N-( N33, N35, N38, N40, N42, N45, N48, N50, N52, N54),
Magnet M-( N33M, N35M, N38M, N40M, N42M, N45M, N48M, N50M, N52M),
Magnet H-( N30H, N33H, 35H, 38H, 40H, 42H, 45H, N48H, N50H),
Magnet SH-( N30SH, 33SH, 35SH, 38SH, 40SH, 42SH, N45SH),
Magnet UH-( N28UH, N30UH, N33UH, N35UH, N38UH, N40UH, N42UH),
Magnet EH-( N26EH, N28EH, N30EH, 33EH, 35EH, N38EH)

Magnet AH-( N28AH, N30AH, 33AH, 35AH)
5.High energy range from 30MGOe to 53MGOe with wonderful coercive force
6. For most applications, coating or plating is recommended.
7. Coatings of Strong NdFeB Motor Magnet Arc shape: Passivation, Nickel, Zinc, Tin, Aurum, Copper, Epoxy, Chemical, etc.

Surface	Coating	Thickness (Microns)	Color	Resistance
