Large Rare Earth Magnet is a alloy magnet of neodymium, iron, boron and other trace metal element. It is the strongest rare-earth permanent magnet

Large Rare Earth Magnets

Sintered NdFeB permanent magnet contains basic raw materials neodymium (Nd) 32%, iron (Fe) 64%, boron (B) 1%, , with small amount of dysprosium (Dy), terbium (Tb), cobalt (Co) , niobium (Nb), gallium (Ga), aluminum (Al), copper (Cu) and other elements, Sintered NdFeB permanent magnetic materials with the high remanence, high coercivity, and was known as the " Magnetic King" The main characteristics of permanent magnetic materials is : good magnetic properties , high temperature performance. High Curie temperature,up to 710 ~ 880 degrees Celsius, the maximum operating temperature up to 250 ~ 350 degrees Celsius. So the stability of permanent magnet magnetic material is best, it is suitable for manufacturing various high-performance permanent magnet electro-acoustic devices.
