The name ceramic magnet comes from ceramic processing technology used in its production. It is a kind of permanent magnet made from iron and barium or strontium.

Due to the cheap, abundant, and non-strategic raw materials used in its manufacturing, the price of ceramic magnet is quite low compared with other permanent magnets. Besides, ceramic magnet has good resistance to corrosion and demagnetization and it can be operated in moderate heat. The following are the key advantages of ceramic magnet:

Does not rust

Cheap but strong

It is hard to demagnetize

Magnetized with multiple poles is acceptable

Not necessary for surface treatment

Ceramic magnet is charcoal gray in color and usually appear in the forms of blocks, discs, rings, cylinders, sometimes arcs for motors and other customized forms.

Applications of Ceramic Magnet

Speaker magnets

DC brushless motors

Magnetic Resonance Imaging (MRI)

Magnetos used on lawnmowers and outboard motors

DC permanent magnet motors (used in cars)

Separators (separate ferrous material from non-ferrous)

Used in magnetic assemblies designed for lifting, holding, retrieving and separating
