Ferrite Magnet

Ferrite Magnet

Description:

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.
