Description of products:
This kind of ferrite magnets are manufactured by AMT&C coporation limited, which produces many different kinds of magnets applying to quite a lot areas. Among them, Ferrite magnets are widely used in our lives including separator and speaker and motor.
Ferrite magnet is a kind of
permanent magnet that made from iron oxide and barium or strontium carbonate by ceramic processing technology. So it's also called as
ceramic magnet.
Special maching process needed for Ferrite magnet because it is brittle. Ferrite magnet can be made to different shapes and sizes by dry pressing then sintered, that is sintered ferrite magnet. Beside sintered ferrite magnet,
bonded ferrite magnet(injection ferrite magnet) is existed. But
sintered ferrite magnet are popular and widely used.
Ferrite magnet are the most commonly used
permanent magnet material just because of its low cost, excellent corrosion and demagnetization resistance properties. Ferrite magnet can be made as isotropic and anisotropic. Isotropic if of the same magnetic properties in all direction, such as Grade-1.
Anisotropic ferrite magnet must be magnetized in the direction of pressing.
