Ferrite magnet is one kind of ordinary and widely used permanent magnets . Ferrite magnets can be divided into isotropic magnets and anisotropic magnets. Both magnetic materials can be manufactured into various finished magnets of different shapes and sizes.
The main grade of isotropic ferrite magnets is Y8T and Y10T. Besides axially magnetization and diametrical magnetization, the isotropic ferrite ring magnets can also be magnetized in a way of radial magnetization or multi-poles magnetization across diameter.
The main grade of anisotropic ferrite magnets is Y25, Y30, Y33, Y35 and Y30BH. The anisotropic ferrite magnets can only be magnetized across diameter or thickness/axially length. Due to the similar manufacturing process, ferrite magnets are called ceramic magnets as well. So they have some other grades named as C5, C8, C8A, C8B, C9 and C10.
Although ferrite permanent magnet is not as strong as SmCo and neodymium ring magnets , they are universally welcomed and applied in many applications owing to their inexpensive cost and moderate magnetic performance. They are used in Speaker, Motor, Ammeter, Sensors, Audio equipment, Phone, Rotors, Filters, Wind Turbines, Generators, TV, Magnetic Holder, Meters, Loudspeakers, Medical Machine products, Magnetic Sport products and so on.
