ndfeb ring magnets

ndfeb ring magnets magnets are currently found in the commercialization of the highest performance magnets, known as magnetic king, we have extremely high magnetic its biggest energy product (BHmax) higher than the ferrite (Ferrite) more than 10 times. Machining performance itself is also very good. Operating temperature up to 200 degrees Celsius. And its hard texture, stable performance, good price, so its application is extremely broad. But because of sm2co17 magnet its chemical activity is very strong, it must deal with its surface coating
