Ferrite permanent magnet ferrite, soft magnetic ferrite, microwave ferrite.
Barium ferrite, strontium ferrite permanent magnet ferrite.
Soft magnetic ferrite nickel and manganese zinc ferrite, zinc ferrite, magnesium, zinc ferrite, microwave ferrite with yttrium ferrite, etc.
There are hexagonal system ferrite, etc.
Ferrite magnets hardness brittle, need special machining process.
Because of its opposite magnet along the direction of manufacturing orientation, you must take along the direction of magnetization, because there is no orientation and the gay magnet, can along any direction of magnetization, in spite of the pressure surface is often the smallest side will find a strong magnetic induction.
Magnetic energy product range in 1.
Mgoe 1 to 4.
0 mgoe between.
Due to low cost, ferrite magnet has a wide application field, from the motor, the speaker to toys, crafts, so it is the most widely used permanent magnet materials.
The role of permanent magnetic ferrite has the following points: 1, the ferrite is not the highest ability of high temperature to 450 degrees?
The ferrite generally can only to 200 degrees.
2, magnetic shielding effect, or absorb electromagnetic waves.
3, adsorption, adsorption force is small, but a bunch of conductive role, more in terms of motor used.
