Ferrite magnets comes in wide ranges of applications because of its high coercively and low cost. Because of its highly efficient machining properties it actually allows them to cut into various shapes and sizes. With diamond tooling drill machine you can cut these magnets into desired shapes and sizes of your choices, but it will not be workable with wire spark erosion techniques. These ferrite magnets have uniquely build which provide perfect resistance to demagnetization / corrosion. For making it suitable and idle, ferrite magnets can be used up to +250 degrees C.
With sub-zero temperatures less than -10 to -20 deg C, it may start to show a reduced pull force (the temperature and the degree of weakening depends on the magnet shape and is application specific; for most uses this effect does not happen as the magnets never get that cold).
Ferrite magnets have some properties which are electrically insulated, and this is the reason it also popularly known as Ceramic magnets. With their high resistivity, It also provides electricity that does not pass easily through them and thus makes it impossible for making wire spark erosion. Typical tolerances for ferrite magnets is +/-0.25mm.
Apart from usual features, these magnets are also come with some distinctive common features and this includes reed switches, loud speakers, security systems, audio and television and holding devices such as pot magnets. Ferrite magnets are often used in electrical motor applications.
Caution: Please make it a note that these are ferrite magnets and these are not same as ferrite cores as we used in transformers. Ferrite magnets are used quite often to retain their magnetism and it’s only transformer ferrites, which have magnetism when there is an electrical current.
