Sintered Ferrite of the main raw material including BaFe12O19 and SrFe12O19, according to the orientation of magnetic crystal divided into isotropic and anisotropic magnets.Due to low cost and moderate magnetic properties and become the most widely used as a magnet..Ferrite magnet is made of by ceramic method, texture is relatively hard, it is a brittle material, due to ferrite magnets have good temperature resistance and low cost, has become the most widely used permanent magnets.
The standard ferrite overbelt magnets are available in both transverse (crosswise) and inline configurations. They are suitable for the largest layer thicknesses. These robust overbelt conveyors have a proven service record stretching back decades.
Ferrite is compounded by many kinds of oxide which is comprised mainly with ferric ion, the material has ferrimagnetism or antiferromagnetic. Mainly includes soft magnet and hard magnet, manganese zinc ferrite, nickel zinc ferrite and manganese zinc ferrite are common soft magnets, the Hard magnet includes barium ferrite and strontium ferrite. The relative permeability of ferrite can reach up to thousands, the resistivity can reach up to 1011 times of metal, the eddy-current loss is small, it is very good to make high frequency electromagnetism part. The disadvantage is machining property not good, low heat stability and saturation flux density.
