Ferrite/Ceramic Magnets
Category: hard ferrite magnets/ china ceramic magnets
Advantages: coercive force is high;strong resistance to demagnetization,suitable for dynamic working magnetic circuit structure;good corrosion resistance,surface treatment not needed
Disadvantages: low magnetic energy; not resistant to low temperature
china ferrite magnetsbelong to sintered permanent magnetic material, which made from oxide iron, barium, and strontium carbonate by ceramic processing technology, just because of the processing method, it also named as ceramic magnets in America.This magnetic material has strong ability to resist demagnetization and the advantage of low cost.
Ferrite permanent magnets classified as isotropic and anisotropic. Isotropic ferrite magnets have weak magnetic strength, but it can be magnetized through different directions. Anisotropic ferrite magnets have stronger magnetic strength than isotropic, but it can be only magnetized through certain direction.
By magnetic strength, ferrite magnets or ceramic magnets are much weaker than neodymium permanent magnets and SmCo magnets, but stronger than AlNiCo magnets. But its advantages of low cost, excellent corrosion and demagnetization resistance, which makes it widely used in the area of magnetic separator, speaker magnets, magnetic toys, office magnets, car magnets. From the aspect of shape, hard ferrite magnets are usually available as ceramic block magnets, ferrite ring magnets, ferrite disc magnets and ceramic block magnets. Ferrite disc magnets often used on office magnets, ferrite ring magnets often used to make loudspeaker, ferrite block magnetscan be used to make separate magnets.
Ferrite magnets (ceramic magnets ) was developed in the year of 1960, and it is lower in power (B, Br, BHmax) compared to other formulations, and are very brittle. However, they have very high Hcj and good Tc, and are quite corrosion-resistant. So ceramic magnets are a cost-effective choice.
ferrite block magnetproduced by powder metallurgy ways, the remanence is low, The coercive force is high, especially suit for magnetic structure used in the condition of dynamic operation. The material is hard and crisp, silicon carbide tools are used for cutting machine. The main material for ferrite magnets is oxide, not easy to be rust. Permanent ferrite is corrosion resistant magnets or corrosion proof magnets material.
