Notes
In collabration with National Defense University of Techonlogy (NDUT), the company has developed bonded NDFeB magnet, which is made of quick-quenching BdFeB magnetic powder and new type of adhesive specially designed for Aeronautics and Space industry by NDUT. In virtue of compressive forming technique,the company can produce the NdFeB magnets with high precision dimension, stable stable properties, good temperature character-istics and anticompression strength. Its surface is resin electrobathed with the extreme temperature up to 180ºC.
The BdFeB magnets the company makes are available in different shapes,such as ring, tile, long stick, cylinder, round, block, widely applied in all kinds of mini-motors, auto motors, air-conditioning motors, automatic controlling devices,sensors,drivers,telecom and instrument industry. |
