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 industrial production.
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 ceramic magnets.
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. If you need the strongest magnetic materials, we suggest sintered NdFeB magnets like N52.
