Ferrite Magnet Composite Magnetic Materials

Ceramic Magnet is a sintered permanent magnet material, which is composed of barium and strontium iron. In addition to strong demagnetization resistance, this kind of magnet has the advantage of low cost. Ferrite magnet is hard and brittle, which needs special machining technology. Heterotropic magnets, because they are oriented in the direction of manufacture, must be magnetized in the direction taken, while homogenous magnets, because they are not oriented, may be magnetized in any direction, although a slightly stronger magnetic induction is often found on the smallest side of the compression plane. The magnetic energy product ranges from 1.1MGOe to 4.0MGOe. Due to low cost, ferrite magnet has a wide range of applications, from motors, speakers to toys, crafts, so it is the most widely used permanent magnet material. characteristic: The powder metallurgy method has low remanence and low recovery magnetic permeability. High coercivity, strong anti-demagnetization ability, especial…
