Rare earth magnets are mostly used in motor, such as permanent magnet D.C. motors, wound field D.C. motors, gear motors, custom DC motors.

Specifiaction of Long arc-segment magnets
1. Specification ofNdFeB Magnets:
Chemical composition: Nd2Fe14B.
NdFeB magnets are hard, brittle and easily corrode.

2. Moderate temperature stability
NdFeB magnets lose -0.09 ~ -0.13% of Br/°C.
Their working stability is under 80°C for low Hci Neodymium magnets and above 200°C for high Hci NdFeB magnets.

3. Excellent strength value
High magnetic performance (Br: 11,000 to 14,500 GS, Hcj: 11,000 to 30,000 Oe, BHmax: 35 to 50 MGOe)

4. Advanced Technology
The choice of Strip casting and HDDR technology in our factory allows us to make high performance NdFeB of N52 possible. The standard properties, N33, N35, N38, N40, N42, N48, N50, N52 (M, H, SH, EH, UH)

5. Extremely resistance to demagnetization
The intrinsic coercive force is over 30,000 Oe, like N35EH and N38EH property. Maximum working temperature: 80 to 200 centigrade. Super strong magnetic force and high intrinsic coercive force and also with precise tolerance

6. Effective surface treatment
Surface treatments have been developed that allow them to be used in most applications. The treatments include Ni, Ni-Cu-Ni, Zn, Ag, Au and other special plating. They are good at anticorrosion.

7. Customized Neodymium Magnets
Most of our magnets are customized. They are produced for customers’ specific using, like arc, tile, square, cylinder and magnetic ring with various sizes. Common specification samples will be available in stock for your testing first.

8. Applications
Security systems, Magnetic separators, Magnetic resonance imaging, Health bandages and plasters, Specialty door catches, Filters & strainers, Sensors, Speakers, Microphones/earphones, High performance motors, Brushless motors, Micro motor, servo motors, VCM(voice coil motor), Automobiles, Magnetic couplings, Magnetic Chucks, Magnetic toys, Magnetic tools, Other magnetic applications
