Ceramic Magnets

Ceramic (Ferrite)Hard Ferrite Magnet
Ceramic magnet material (Ferrite) is Strontium Ferrite. This material is one of the most cost effective magnetic materials manufactured in industry. The low cost is due to the cheap, abundant, and non-strategic raw materials used in manufacturing this alloy. The permanent magnets made with this material lend themselves to large production runs. This magnet material has a fair to good resistance to corrosion and it can operate in moderate heat. The majority of the world¡¯s Ceramic magnetic material comes from China because of the alloy¡¯s commodity nature and the high tooling costs found in the west. Ceramic magnets have a low Energy Product and they are usually used in an assembly containing mild steel.
