Ferrite is SrO and Fe2O3 as the main raw material, through the ceramic sintering process method, the product can be made into the shape of a circular, cylindrical, square and tile shape. Our products are mainly used in various types of motors, especially used in a variety of motor car, motorcycle starter motor and household class fitness equipment, electric toys and other motors. The Curie temperature refers to the ferromagnetic material may be between the temperature change of the magnet rolls. The Curie temperature of the ferrite is 450 ° C. If ferrite bake in the oven with the temperature demagnetization phenomenon occurs. Until the Curie temperature magnetic completely dissipated. Difference ferrite magnets and NdFeB magnets magnetized machine comprising: two magnets needed to reach saturation magnetization different magnetic field strength, which is different magnetizing machine power, charge NdFeB magnetizing machine power to be larger. Ferrite magnets role is gyromagnetic material metal at high frequencies and microwave frequencies will have a huge vortex effect, leading to metal magnetic unusable, and ferrite is very high resistivity, will effectively overcome this problem, widely used.
