Advantages: NdFeB magnets have very high Magnetic properties. Their (BH)max value is 3 to 10 times higher than sintered ferrite magnets. Hci value is 5 to 10 times higher than sintered ferrite magnets and 5 to 15 times higher than AlNiCo magnets. The potential Magnetic properties of NdFeB magnets are very high. Theoretically, their (BH)max value can be as high as 527 KJ/M3 (66 MGOe). NdFeB magnets is cheaper than smco. Since the major raw material Fe is very cheap. The capacity of another major raw material Nd is 10 to 16 times higher than Sm on earth. So the Price of NdFeB magnets is lower than SmCo magnets. NdFeB magnets’ mechanical property is better than SmCo magnets and AlNiCo magnets. They can be cut and drilled easily. The temperature properties of NdFeB magnets are low compare with other magnets. The maximum working temperature is usually 80ºC ,or 180ºC after special treatment. Disadvantage :NdFeB magnets are very easy to get rusted , they must be protected using special coating, such as Zn, Ni, Au, Epoxy. |
