Detailed Product Description
1.Material: Sintered Neodymium-Iron-Boron.
2.Size: It will be different according to client's requirement;
3. Magnetic property: From N35 to N52, 35M to 50M, 35H t 48H, 33SH to 45SH, 30UH to 40UH, 30EH to 38EH;we are able to manufacture the full range of Sintered Nd-Fe-B products including the high energy magnets such as N52, 50M, 48H, 45SH, 40UH,38EH,34AH, (BH)max from 33-53MGOe, maximum working temperature up to 230 Degrees Centigrade.
4. Coating: Zn, Nickle, silver, gold, epoxy and so on.
5. Advantage:
a. Chemical Composition: Nd2Fe14B: Neodymium magnets are hard, brittle and easily corrode;
b. Moderate Temperature Stability: Neodymium magnets lose -0.09~-0.13%of Br/°C. Their working stability is under 80°C for low Hcj Neodymium magnets and above 200°C for high Hcj Neodymium magnets;
c. Excellet Strength Value: The highest(BH)max reaches up to 51MGOe;
6. Application: sensors, speakers, brushless motor, DC motor, Step motor, wind turbine/wind generator, magntic hooks, magnetic filter, cup magnet, Automobiles, magnetic coupling, magnetic chuch, permanent magnetic lift, and so on.
We always produce the magnet according to client's request.
