Effect of different temperature on properties of NdFeb
Time:07/08/2020
Different temperature has great influence on the performance of NdFeb.
 
1. Ambient temperature
 
Since ndFeb magnets are sensitive to working temperature, both the immediate maximum temperature and the continuous maximum temperature in the environment may demagnetize the magnet to different degrees, including reversible and irreversible, recoverable and irreversible. The effect of different temperature on the performance of NdFeb can be seen from the demagnetization curve.
 
2. Maximum operating temperature
 
Temperature limitations on NdFeb magnets have led to the development of a range of grades of magnets to suit different operating temperature requirements. Please refer to our performance catalog to compare the operating temperature range of the grades of magnets. Confirm the maximum operating temperature before selecting the NdFeb magnet.
 
3. Curie temperature
 
The Curie temperature of NdFeb is 320℃-460°C. The Curie temperature or magnetic transition point refers to the temperature at which the material can change between a ferromagnet and a paramagnetic body, that is, the transition temperature of the ferroelectric body from the ferroelectric phase to the paramagnetic phase. The temperature corresponding to the disappearance of ferromagnetism is the Curie point temperature.
