The ferrite magnets standing for ceramic magnets feature the good resistance to demagnetization and have good corrosion resistance. This class of permanent magnet is hard and brittle so as not to be exposed to high compressive forces. The hard ferrite magnets have high coercivity, meaning that the materials are hard to become demagnetized. Literally, it doesn’t demagnetize and be rust easily.
The ferrite magnets including “Isotropic” and “Anisotropic” are sintered magnet with either by dry pressed or wet pressed. Tooling is always needed when pressed. The key advantage of ceramic magnets is that it can be magnetized with multiple poles if necessary. That is to say, the magnetization can be done by axially, radially, multi-poles axially, and multi-poles on circumference etc.
