Ferrite Magnet(Ceramic Magnet)
Ferrite Magnet is manufactured from oxide material by powder metallurgical process. Its advantages include:
low-cost excellent corrosion resistance, resistance to be demagnetized etc. The normal working temperature of
Ferrite Magnet is between-40C and +250°C.It can be magnetized before or after assembling. Generally, Ferrite
Magnet can be machined to regular shapes like segments, blocks, rings and discs etc. The normal grades for
sintered Ferrite Magnets are Y10,TY25, Y30, Y30BH, Y35, etc.
➢ Advantages of Ferrite Magnet:
Ferrites have isotropic characteristics, weak magnetic performance, has the same magnetic performance in any
direction, multipolar magnetic charge. The main raw material of ferrite is oxides, so it is not corroded by high
temperature, high humidity or chemicals (except strong acid and base); with excellent diamagnetic impedance,
no flux loss before and after assembly and magnetic charging; working temperature is-40℃ to + 250℃, poor
temperature coefficient; Br temperature coefficient is-0.2% / ℃, 0.2% under Br, etc. per 1℃ increase; high hardness,
wire cutting and grinding; ferrite is brittle and fragile during production and transportation. magnetic
requirements and good for strict working environment requirement.
➢ Application of Ferrite Magnet:
It is widely used in permanent magnet motor, DC motor, speaker, dry clarinet, magnetic separator machine,
Magnetic Knife Holder/Rack, General Holding Devices and adsorption device and so on.
