Ceramic magnet material (Ferrite) is one of the most cost effective magnetic materials. It has a fair to good resistance toward corrosion and it can operate in moderate heat. Ceramic (Ferrite) magnets have low energy product and they are usually used in assemblies containing mild steel.
Ceramic magnets are manufactured using powder technology techniques. The primary raw material – ferrite – is made by using iron oxide and strontium carbonate. Ferrite represents more than 75 percent of world magnet consumption (by weight). It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.
