China Ceramic Magnets, Ferrite Magnets |

Ceramic, also known as Ferrite
magnets, which are made of a composite of iron oxide and barium/strontium
carbonate by ceramic processing technology, are the least expensive
class of permanent magnet materials, easily machinable, have high
coercive force. By strength, ceramic are stronger than Alnico magnets
but weaker than neodymium magnets and SmCo magnets.
Ceramic magnets are manufactured by die pressing and then sintering.
This process provides an economical means of production of various
shapes and sizes. Ceramic magnets can be produced with either isotropic
or anisotropic properties. Ceramic-1 is an isotropic grade with
equal magnetic properties in all directions. Ceramic grades 5 and
8 are anisotropic grades. Anisotropic magnets are magnetized in
the direction of pressing.
Ceramic magnets have a good balance of magnetic strength, excellent
corrosion resistance and normal operating temperatures between -40C
and 250C. They are the most widely used magnets today, can be found
in a wide variety of applications-
- Automotive applications
- Industrial and consumer motors
- Industrial holding applications
- Material handling
- Computer peripherals
- Speakers
