Low temperature coefficient technology

Our low temperature coefficient NdFeB series, remanence temperature coefficient α (20~MT) as low as -0.095%/°C, compared with conventional temperature coefficient magnets, low temperature coefficient magnets have better anti-demagnetization ability and magnetic flux density consistency, for example: 35UHT low temperature coefficient magnet magnet is baked at 180°C constant temperature for 200hrs, and the magnet loss rate is less than 1%; At the same time, the magnet also has the characteristics of low weight loss, at 130°C, 100%RH, 2.7atm, 168hrs, its weight loss rate is less than 0.5mg/c㎡, after the surface of the magnet is passivated, it can be stably served for more than 20 years in a sealed environment.
