Ferrite magnets, a type of sintered permanent magnet, are composed of barium and strontium ferrites. These magnets not only possess strong resistance to demagnetization but also offer the advantage of being cost-effective. Ferrite magnets are hard and brittle, requiring special mechanical processing techniques. For anisotropic ferrite magnets, the orientation is along the manufacturing direction, so they must be magnetized along that direction. On the other hand, isotropic ferrite magnets, which lack orientation, can be magnetized in any direction, although a slightly stronger magnetic induction is often found on the smallest surface under pressure. The main raw materials are oxides, making them resistant to corrosion. Operating temperature: -40°C to 200°C. Ferrite magnets have a wide range of applications, from motors and speakers to toys and crafts, making them the most widely used permanent magnets today.
