Sintered ferrite magnets and hard ferrite magnets are available as isotropic magnets and anisotropic magnets. The magnetic properties of isotropic ferrites are low, since they have nearly the same magnetic properties in all directions, isotropic ferrite magnets can be magnetized in many different directions or in multi-poles. Anisotropic ferrite magnets have better magnetic properties compared with isotropic ferrite magnets. However this type of magnet can only be magnetised along a preferred direction.
Due to low material costs and ease of production, ferrite magnets can be cost affective.
Ferrite magnets can be used between -40°C and +200°C
They can be cut using diamond tools
The raw material of sintered ferrite magnet is oxide, so ferrite magnets will not rust under severe environments, nor will they be affected by chemicals (except some strong acids).
Widely used in many different applications, such as motors and loudspeakers.
