It is found in highest commercial performance magnets, known as Magneto, with a high maximum magnetic energy product (BHmax) higher than ferrite (Ferrite) 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 its strong chemical activity, it must deal with its surface coating. (E.g. plating Zn, Ni, electrophoresis, passivation)
