High Temperature Magnets
China High Temperature Magnets AlNiCo, SmCo, Neodymium Magnet
High Temperature Magnet:
It refers some magnets that works at very high temperature without losing magnetic force. AlNiCo rare earth magnet is the highest, it can be used under 450°C-550°C, we also have other permanent magnets including sintered neodymium magnet and SmCo magnet neodymium can work under temperature of 200°C, sintered SmCo can be used under 250-350°C.
