    Neodymium magnet is also known as Nd-Fe-B magnet, strong magnet. It is the strongest permanent magnet. It is composed of rare earth neodymium, metal praseodymium, iron, aluminum, boron-iron alloy, and other rare earth materials.


    Advantages of Sintered neodymium magnet:

    The mechanical properties of Nd-Fe-B magnet is better than samarium-cobalt magnet and Alnico magnet, so it is easier to cut and drill as ring, arc, bread shape and other complex and irregular shape to meet special applications. Compared with the other permanent magnets, the BHmax value of neodymium magnet is 5-12 times as the ferrite magnets, and 3-10 times as Alnico magnet. The Hcb value is 5-10 times as ferrite magnet, and 5-15 times as Alnico magnet.

    On the basis of coercivity, sintered neodymium magnet can be classified into low-coercivity (N series), medium coercivity (M series), high coercivity (H series), super high coercivity (SH series), ultra-high coercivity (UH series, even EH series).

    According to the difference of BHmax, there are six series: N35-N52, N30M-N50M, N30H-N48H, N28SH-N45SH, N28UH-N42UH, and N28EH-N38EH. More details please find the property table.

    China Magnets Source Material Limited can manufacture various grades neodymium magnet. Customers can choose grade according to the desired operating temperature. N-series magnets is able to bear working temperature 80℃, M-series for operating temperature 100℃, H series magnet for 120℃ , SH series magnet for 150℃, UH series magnet for 180℃, EH series magnet for 220℃
