About Ferrite/Ceramic magnet
Ferrite magnets, also known as ceramic magnets, are a type of
magnetthat is made out of a mixture of metals that is called
ferrite. Ferrite is madeup mostly of a chemical element called iron
oxide.
They are commonly used in various applicatio int he past several
decades, such as loudspeaker, motor, and generators.
Market share of Ferrite magnets is till very large even the
aplication range of sintered Neodymium magnets is more and more
extensive. As a nonmetallic type permanent magnetic material,
ferrite magnets are utilizing Fe2O3, Bao or Sro as raw aterial and
then manufactured through ceramics process, thus can be classified
to isotropic type and anisotropic type. It maximum operating
temperature can arrive 250 Degrees celsius and also has superior
corrosion resistance.
Ferrite magnets are not easy to be demagnetized, not easy to be
corroded, their production process is simple, and their price is
relatively low. Therefore, the output of ferrite magnets is the
highest in the entire magnet industry, and they are widely used in
industrial production.

Processing of Ferrite magnet
1. Dry process:
By dry process, can produce isotropic & anisotropic magnets.
The tool can be changed and developed easily.
2. Wet process:
By wet process, only anisotropic magnets can be produced. It is
complicated to change the tool and the tooling charge is much
higher.
Application:
Fridge magnets and novelty items, Loudspeakers, Security systems, Pot magnets, Very large plate magnets to remove ferrous contamination from
processing lines Motors, generators and alternators, Medical instruments, Lifting magnets, Sea searcher magnets, Eddy current devices Brakes, Clamps Switches and relays Sweeper magnets.
