Product Description
Block Rare Earth Neodymium Holding Magnet with a Hole
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 deg C.
N33M-N50M, For working tem less than 100 deg C.
N30H-N48H, For working tem less than 120 deg C.
N30SH-N45SH, For working tem less than 150 deg C.
N30UH-N38UH, For working tem less than 180 deg C
N28EH-N35EH, For working tem less than 200 deg C.
A30AH-A33AH, For working tem less than 220 deg C.
NdFeB Magnet Application:
Sintered NdFeB material has excellent magnetic properties, widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields, the more common are permanent magnet motors, speakers, magnetic separator, computer disk drives, magnetic resonance imaging instruments, etc.
