Material description and demagnetization curve of neodymium magnet N40

Addtime:2023-01-04 10:55:03 Click:392

N40 magnets, a medium grade of neodymium magnets, are mostly used in motors, sensors, electronics, industry, optics, medical equipment, magnetic separation and many other industries. They are widely used. Some engineers are more concerned about whether the material is N40 or not. The content should be carefully read.


This is an important material proof. After the NdFeB blank material is sintered, the N40 grade demagnetization curve above is obtained by the demagnetization curve instrument.

N40 magnet demagnetization curve

The picture below is the international standard for the material grade of N40, and the test values in the picture are based on Figure 1.

Magnetic and physical properties of N40

We can see that the data in Figure 1 is in full compliance with the international standards in Figure 2, which proves that the material meets the performance standards of NdFeB N40 grades.


Welcome customers from all over the world to consult us to buy N40 grade neodymium magnets, specifications and shapes can be customized.
