The magnetic performance indicators of bonded ferrite products mainly include residual magnetic induction intensity Br, intrinsic coercive force Hcj, maximum magnetic energy product (BH)max, etc. With the development of miniaturization of electronic components, the volume of magnets is getting smaller and smaller, so the performance of magnets must be developed towards high performance. The magnetic properties of bonded ferrite are determined by the filling rate of magnetic powder in the magnet, the degree of orientation of magnetic powder and the intrinsic properties of magnetic powder.Its advantages are that the appearance of the product is smooth and flawless, the dimensional accuracy is high, the consistency is good, no subsequent processing is required, the performance is stable, and the magnetic energy product of any size from the maximum value to zero can be generated, and the temperature stability is good, and the corrosion resistance is good. High coercive force, shock resistance and impact resistance are good, meanwhile the product can be complicated to be processed into different shapes.It is mainly used in home appliances, automobiles and office fields such as copiers, printer magnetic rollers, hot water pumps for electric water heaters, fan motors, automobiles, motor rotors for inverter air conditioners, etc.
