China Rare Earth Magnet Limited supplies high temperature magnets - AlNiCo magnet, SmCo magnet & Neodymium magnet


 
High temperature magnet: It refers some magnet that works at very high temperaure without lossing magnetic force. Sintered NdFeB magnet can work under the temperature of 200°C, Ceramic (hard Ferrite) magnet under 350°C, Sintered SmCo under 250-350°C and Sintered AlNiCo magnet under 450-550°C.
