Maximum working temperature and Curie temperature of neodymium magnet

Addtime:2022-03-09 16:42:19 Click:784

What is the maximum working temperature of NdFeB(neodymium) magnets? What happens if the magnet exceeds this temperature? What does the Curie temperature of NdFeB magnets mean? In this article, we'll try to simplify some of these concepts and answer some common questions.


Definition

Curie temperature is the temperature at which all magnetization of a magnet disappears.


The maximum operating temperature refers to the number at which each different grade of magnet material works.


While not very accurate, it is a good guideline and applies in many situations.


Between the maximum operating temperature and the Curie temperature, some percentage of the magnetization is irreversibly lost.


Some basic knowledge;

NdFeB magnets are classified into N, NM, NH, NSH, NUH, NEH grades of magnets according to different working temperatures.


For these grades, you can check some information on NdFeB permanent magnets.


See also, the introduction of magnet grades/magnet grades.


The figure below lists the maximum working temperature and its Curie temperature of different grades of NdFeB magnets.

Conclusion;

The working temperature of the N gear is 80°C, which means that when the NdFeB magnet product reaches the working temperature of 80°C, it will start to demagnetize and the magnetic properties will be lost. When the temperature is getting higher and higher, when the temperature reaches 310 ℃, the NdFeB magnet will completely lose its magnetic properties. This 310℃ is the Curie temperature of N-grade NdFeB magnets.


Magnets of NM, NH, NSH, NUH, NEH grades correspond to the corresponding temperature coefficients according to the figure.
