1.introduction of ndfeb magnet
Sintered NdFeB Magnet is one of the high performance rare earth permanent magnets, which use neodymium (ND), iron (Fe), and boron (B) as their main ingredients and is susceptible to be demagnetized when exposed to increasing temperatures. By adding some necessary rare earth elements, neody
mium magnets can withstand higher temperatures varying from 80~220 Celsius degree. Neodymium magnets are classified into different grade like N, M,H, SH, UH, EH, AH,ETC by magnetic energy and temperature resistance ability. Pls See attached Magnetic property lists.
