The NdFeB magnet was developed in the early 1980s. It is the most magnetic powerful magnet in the world and it is known as the king of magnets. With the high remanence, high coercivity and high magnetic energy product, the maximum working temperature is up to 250℃, and has good machinability. Due to the weak corrosion resistance, it must be electroplated and other surface treatment. So that it can meet the requirements of different working environments. Widely used in automobile, wind power, robot, industrial motor, audio&speaker, sensor, consumer electronics and medical devices and other fields.
