Ferrite magnet is a permanent ferrite magnet mainly made of SrO or BaO and Fe2O3. Compared with other permanent magnets, ferrite magnets are hard and brittle with low magnetic energy, but they are not easy to demagnetize. It is not easy to corrode, the production process is simple and the price is low. Therefore, the output of ferrite magnets in the entire magnet industry is high and they are widely used in industrial production.
Ferrite magnets are sintered permanent magnet materials, composed of barium and strontium ferrite. In addition to strong anti-demagnetization properties, this ferrite permanent magnet material also has the advantage of low cost. Permanent ferrite magnets are hard and brittle and require special machining processes. The magnets of the opposite sex must be magnetized in the direction because they are oriented along the manufacturing direction, while the magnets of the same sex can be magnetized in any direction because they are not oriented, although a slightly stronger magnetic induction will be found on the pressure-bearing surface, which is often the smaller side. . The magnetic energy product range is between 1.1MGOe and 4.0MGOe. Due to their low cost, ferrite magnets have a wide range of applications, ranging from motors and speakers to toys and handicrafts. Therefore, they are currently the most widely used permanent magnet material.
Ferrite magnet material characteristics
Permanent ferrite magnets are produced using powder metallurgy methods and have low residual magnetism and low recovery magnetic permeability. It has large coercive force and strong resistance to demagnetization, and is particularly suitable for use as a magnetic circuit structure under dynamic working conditions. The material is hard and brittle and can be used for cutting with emery tools. Ferrite permanent magnet material is an oxide, so it is not easy to corrode. Working temperature: -40℃ to +200℃.
Ferrite magnets are divided into anisotropy (isotropy) and isotropy (isotropy). The isotropic sintered ferrite permanent magnet material has weak magnetic properties, but can be magnetized in different directions of the magnet; the anisotropic sintered ferrite permanent magnet material has strong magnetic properties, but can only be magnetized along the direction of the magnet. Magnetize in the predetermined magnetizing direction.
