Sinter NdFeB Magnet

NdFeB magnet is a rare earth permanent magnet material with extremely high magnetic energy product and coercive force, as well as excellent corrosion resistance, wear resistance and thermal stability. It is one of the strongest permanent magnet materials that can be manufactured at present, and can be used to manufacture various high-efficiency motors, generators, acoustic equipment, sensors, etc.

Note: (1) The data in the table are the test results at an environment of 20°C; (2) The definition of the maximum operating temperature Tw: D10*7↓The sample column is kept at a certain temperature for 2 hours, and its magnetic flux loss is ≤5%, then Its maximum service temperature;

(3) Adding "-T" after the grade indicates that Hcj is more than 1kOe higher than the standard value; adding "-C" after the grade indicates low weightlessness requirements.
