Ferrite magnets are also known as Ceramic Magnets, Ceramic Ferrite Magnets, Feroba Magnets, and Hard Ferrite Magnets. They are corrosion-free and can be used in damp, wet, or marine environments. With a working temperature range of -40°C to +250°C, they are suitable for various applications such as motors, generators, loudspeakers, and more.
There are 27 grades of Ferrite Magnets available, with C5 and C8 being the main grades used today. C5 is a general choice for applications like overband magnets, while C8 is preferred for loudspeakers and motors due to its higher coercivity.
Ferrite magnets are ferrimagnetic in performance and are commonly used in industries such as automotive, aerospace, military, and electronics. They are permanent magnets that retain their magnetism and are different from soft ferrites used in transformers.
Isotropic sintered ferrite permanent magnetic materials have weak magnetic properties but can be magnetized in different directions. On the other hand, anisotropic sintered ferrite permanent magnetic materials have strong magnetic properties but can only be magnetized in a predetermined direction.
