Permanent 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 demagnetization
when exposed to elevated temperatures. There are many grades which
can withstand high temperatures, but several factors will dictate the
performance of the Neodymium magnet.
The Characteristics of Permanent Sintered NdFeB Magnet:
Super strong Br Resident induction.Excellent demagnetization resistance capability.
Good Price relative to its high magnetic properties.
Coating is needed for NdFeB
