Hard Anisotropic Ferrite Magnet

Ceramic magnets (also known as "ferrite" magnets) are part of the permanent magnet family and are currently the lowest cost hard magnets.

The ceramic (ferrite) magnet composed of strontium carbonate and iron oxide has medium strength and can be used at quite high temperature.

Process of Ferrite Magnet manufacturing

Raw Material--Mixing / Milling--Calcination--Coarse Milling--Wet Milling--Pressing--Sintering--Grinding&Finishing--Final Inspection--Packing and Dispatch

Advantages of Ferrite Magnets
Do not corrode in water.
Can be used up to ﹢250 degrees C.
Sometimes up to +300 degrees C in special circumstances.
High coercivity (Hci) that increases as magnet heats up.
Electrically insulating.
Low cost.
