01.Ceramic /Ferrite Magnets Introduction
Ceramic magnet, i.e. ferrite magnet, is a kind of permanent magnet
mainly manufactured by raw material of (SrO) SrO or BaO and Fe2O3.
Compared with other magnets, ferrite magnet is hard and brittle,
and the magnetic energy is relatively low. But it is difficult to
demagnetize and go corrosion, the production process is simple and
the price is cheap, therefore, in the whole magnet industry the
output of ferrite magnet is the highest and they are widely used in
Ferrite magnets belong to sintered permanent magnetic materials ,
are composed of barium or strontium iron body mainly. This kind of
magnet has a strong resistance to demagnetization, and owns the
advantages of low cost in addition. Ferrite magnets are hard and
brittle. They need special machining process in production. It can
be divided into anisotropic magnets and isotropic ferrite magnets.
The magnetism orientation of anisotropic ferrite magnets is
oriented in a certain direction, and can only be magnetized along
this direction. While there is no certain orientation of isotropic
ferrite magnets, so they can be magnetized along any direction
after production. Isotropic ferrite magnet is relatively weaker
than anisotropic one. The magnetic energy product range of ferrite
magnets is between 1.1 MGOe to 4.0 MGOe. Owing to the low cost and
economic effect, ferrite magnet has a very wide application field
from the motors, the speakers, the toys to crafts, so it is the
most widely used permanent magnet material.
02.Typical Magnetic Performance for Ceramic Magnets
Mostly Used Standard
|Grade||Value(min/typical in our factory)|
OX100=Y10T=C1 OX300=Y30=C5 OX330=Y30BH
The standard from International Electronics Committee(IEC404-8-1)
|Grade||Allowed Value (min/typical)|
Ferrite magnets are permanent magnets , not rare earth magnets, it is mainly made from iron oxide and
strontium carbonate by ceramic processing technology, also called
Ferrite magnets are brittle, can be manufactured by die pressing
and then sintering, can be made into various shapes and sizes. Its
normal operating temperature is between -40℃ and 250℃. Ceramic
magnets are the most commonly used permanent magnet materials due
to their low cost, easy to produce, excellent corrosion and
demagnetization resistance properties. It can be produced either
isotropic or anisotropic. C3, C5 & C8 magnets are anisotropic.
