permanent magnet for motor NdFeB Magnet

1. Magnetic properties: Sintered 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 and is susceptible to demagnetization when exposed to elevated temperatures.

2.Characteristics:

1.Super strong Br Resident induction.
2.Excellent demagnetization resistance capability.High coercive force, the max working temp is up to 240°C or says 489.6F

3. Grade:N33-N52, 33M-48M, 33H-48H, 30SH-45SH, 30UH-40UH, 28EH-38EH, 28AH-35AH

4. Shape: Disc(Cylinder), Block, Ring, Countersunk, Segment and more, trapezoid, irregular shape, customized shapes are available

5. Max. Size shape: Length or Outer diameter 220mm

6. Coating:Ni, Zn, NiCuNi, gold, copper, epoxy, chemical, parylene, Everlube, passivation ,tin and CR3 + Zn

7. Application:Widely used in different applications, such as motors, sensors, microphones, wind turbines, wind generators, VCMs in hard disk drives, printer, switchboard, loudspeakers, magnetic separation, magnetic hooks, magnetic holder, magnetic chuck, Computer rigid disc drives ,

Magnetic resonance imaging , common daily use and so on.

8. Advantages:Own ourselves R&D center, Quality control center and professional machine technicians, which can help to control well in quality, tolerance, process cost and delivery.

9.Surface Treatment Method:
a)Metallic Zinc, Nickel, Nickel+Nickel, Copper+Nickel, Nickel+Copper+Nickel,
b)Temporary Surface: Passivation
c)Dimension are Available Attributes of Neodymium Magnets:
d)Very high resistance to demagnetization High energy for size Good in ambient temperature Moderately priced Material is corrosive and should be coated for long term maximum energy output Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced perio.

Standard Specification for Sintered NdFeB Magnets:
