Ferrite magnet sintering permanent magnetic material, is composed of barium and strontium iron body, this kind of magnets in addition to a strong resistance to demagnetization, and the advantages of low cost.Ferrite magnets hardness brittle, need special machining process.Because of its opposite magnet along the direction of manufacturing orientation, you must take along the direction of magnetization, because there is no orientation and the gay magnet, can along any direction of magnetization, in spite of the pressure surface is often the smallest side will find a strong magnetic induction.Magnetic energy product range between 1.1 MGOe to MGOe 4.0.Due to low cost, ferrite magnet has a wide application field, from the motor, the speaker to toys, crafts, so it is the most widely used permanent magnet materials.
