Sintered Ferrite Ceramic Magnets

Sintered Ferrite Ceramic Magnets

Application:Used in cars, water pumps, disk drivers, starting motors of motor bikes and stepping motors
Advantage:
1.Cheapest magnet material
2. Good anti-corrosion performance, no surface treatment needed.
3.Excellent temperature stability
4.Compact crystal
5.Could provide isotropic and anisotrpic

Sintered Ferrite Magnets includes Barium ferrite and Strontium ferrite, the production process is similar with ceramic crafts. Ferrite magnets are brittle and magnetic power is low, but magnetic properties is stable, and featured with high resistivity , Ferrite magnet is not easy to demagnetize and rust, the production process is simple and cost is inexpensive. Thus, ferrite magnets are widely used in industrial production, such as speakers, crafts, toys and so on.
65% are arc shape we supplied. Arc shape magnet is mainly used for permanent magnet DC motor and some small engines. At presently, our factory provides ferrite products with Y10, Y30, Y30H, Y35 Grades and so on.
