The advantage is high cost-effective, with good mechanical properties, easy cutting; according customer's demand to manufacture in a wide range of shapes, sizes and grades.
Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.The magnet material is currently the strongest type of permanent magnet in the world.
Pic shows the Sintered NdFeB Magnet block with NiCuNi coating,the magnetized direction is through the thickness.
pls see follows table for the EH grade and its details properties,the maximum operating temperature is reach 200 degree..
Sintered NdFeB Magnet block magnetic energy parameters:
