long Block permanet Sintered NdFeB magnet
neodymuim magnets, permanent rare earth neodymuim magnets,sintered permanent neodymuim magnets, ball neodymuim
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.
We are China industrial Block permanet Sintered NdFeB magnets manufacturer offer best industrial Block permanet Sintered NdFeB magnets OEM, ODM,service.
Due to the much longer dimension, we can not use normal process to make the length, the bigger machine or wire-cutting machine is needed.
