    Ferrite Magnets are also known as Ceramic Magnets, Ceramic Ferrite Magnets, Feroba Magnets and Hard Ferrite Magnets. Ceramic Ferrite magnets are one of the most widely used permanent magnet materials in the world. Ferrite magnets are a low cost magnet material perfectly suited for higher volume production runs . 

    They are termed ceramic due to their excellent electrical insulation ability. Ferrite magnets are superb in damp, wet or marine environments – Ferrite magnets are corrosion free. Because the iron is already in a stable oxidized form in its structure, the iron cannot oxidize (“rust”) any further when in water.


    • It has the advantages of good anti-demagnetization and low cost.

    • It is produced by powder metallurgy method, with low remanence and low return magnetic permeability.

    • The material is hard and brittle.

    • The main raw material is oxide, so it is not easy to corrode.

    • Working temperature: -40 ℃ to + 250 ℃.

    • Isotropic sintered ferrite permanent magnetic materials have weak magnetic properties, but can be magnetized in different directions.

    • Anisotropic sintered ferrite permanent magnetic materials have strong magnetic properties, but can only be magnetized in a predetermined direction.
