High temperature magnets can work at very high temperature without losing magnetic force.
|
High temperature magnet:
It refers some magnet that works at very high temperature without losing magnetic force. AlNiCo rare earth magnet is the highest, it is under 450-550°C, we also have other rare earth magnet including NdFeB rare earth magnet and SmCo rare earth magnet, Sintered NdFeB rare earth magnet can work under the temperature of 200°C, Sintered SmCo rare earth magnet under 250-350°C.
