Ferrite, also known as Ceramic Magnets, are made of a composite of Iron oxide and barium carbonate (BaCO3) or strontium carbonate (SrCO3). Since th 1950’s, this material is commonly available and at a lower cost than other types of materials used in permanent magnets. Ceramic magnets are made by pressing and sintering. Sintered magnets are a type of ceramic composed of the compressed powder of the alloy material being used. Sintering involves the compaction of fine alloy powder in a dry and then fusing the powder into a solid material with heat. While the sintered magnets are solid, their physical properties are more similar to a ceramic and are easily broken and chipped.
Ferrite magnets are brittle and hard , which generally requires diamond wheels to grind and shape. These magnets come in a number of different grades. Ferrite Multipolar Ring Magnets, 2-Polar Ring Axial Ferrite Magnet, Planar Block Ferrite Bipolar Magnet

Advantages of Bonded Magnets
*Produced with high efficiency, stability and repeatability.
*Magnet and other part may form together in one step.
*Free choice of magnetizing direction-especially for multi-polar applications
*High dimensional accuracy-large quantity applications with minimum post-press machining.
*Thin-wall ring and complex shape magnets.
*High resistance to corrosion.

The complete combination of injecting process and high-property rare-earth powder makes it possible to form easily the anisotropic(especially radial anisotrotropic)super-thin ring or block magnets in complex shapes.The products can be formed in a unit together with other components.This process provides high precision and high acceptable rate of products.
