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.

SHANGHAI CJ MAGNET INDUSTRY CO., LTD. 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.

Common Use

• Magnets can be used in scrap and salvage operations to separate magnetic metals (iron, cobalt, and nickel) from non-magnetic metals (aluminum, non-ferrous alloys, etc.). The same idea can be used in the so-called "magnet test", in which an auto body is inspected with a magnet to detect areas repaired using fiberglass or plastic putty.
• Magnetic levitation transport, or maglev, is a form of transportation that suspends, guides and propels vehicles (especially trains) through electromagnetic force. Eliminating rolling resistance increases efficiency. The maximum recorded speed of a maglev train is 581 kilometers per hour (361 mph).
• Magnets may be used to serve as a fail-safe device for some cable connections. For example, the power cords of some laptops are magnetic to prevent accidental damage to the port when tripped over. The MagSafe power connection to the Apple MacBook is one such example.
