NdFeB Magnets Information
Sintered Neodymium 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. Neodymium magnet is a new kind of magnetic material developed with excellent magnetic characteristics. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs. There are many grades which can stand high temperatures.
