The character designation of sintered NdFeB magnets is composed of NdFeB, the chemical symbols of neodymium, ferrum and boron, and two magnetic properties. The number in front of the solidus refers to the maximum magnetic energy product, symbol BH max and unit kj/m. The number after the solidus refers to one-tenth of magnetic polarization intensity coercivity, symbol Hcj and unit KA/m, rounded to the nearest integer.
Work Tem of Neodymium magnet:N33-N52, For working temp less than 80 ºC.
N33M-N50M,For working tem less than 100 ºC.
N30H-N48H, For working tem less than 120 ºC.
N30SH-N45SH, For working tem less than 150 ºC.
N30UH-N38UH, For working tem less than 180 ºC
N28EH-N35EH, For working tem less than 200 ºC
