Hard Ferrite magnets are commonly known as Ceramic magnets due to the process used to produce them. Ferrite magnets are manufactured mainly of strontium or barium ferrites and iron oxide. Hard Ferrite magnets are produced as Isotropic and Anisotropic types. Isotropic type magnets are produced without orientation and can be magnetized in any direction. On the other hand, Anisotropic magnets are exposed to an electromagnetic field during their process to achieve higher magnetic energy and properties.
Ferrite magnets have good resistance to demagnetization and with their high Curie temperature they have excellent high working temperatures and most of all they have excellent resistance to corrosion. Ferrite magnets are excellent choices for many applications due to their economical low price and abundance of raw materials and they do not fluctuate much in price. They are the most widely used magnets in a wide range of applications.
