Ferrite magnet belongs to sintered permanent magnet material, which is composed of barium and strontium ferrite. This kind of magnetic material not only has strong anti demagnetization performance, but also has the advantage of low cost. Ferrite magnet is hard and brittle, which needs special machining process. BHmax ranges from 1.1 mgoe to 4.0 mgoe. Due to the low cost, ferrite magnet has a wide range of applications: motors, loudspeakers, toys, crafts ,etc., so it is the most widely used permanent magnet materials. Ferrite Magnet is produced by powder metallurgy with low remanence and low recovery permeability. High coercivity and strong demagnetization resistance makes it especially suitable for magnetic circuit structure under dynamic working conditions. Ferrite Magnet can be used for cutting with emery tools. The main raw material is oxide, so it is not easy to corrode. The working temperature is: - 40 ℃ to + 200 ℃.
