Ferrite Segment Magnet is also known as a Ceramic Magnet and even as Permanent Ferrite magnet. The name is interchangeable but they all refer to exactly the same material type. They are known as Ceramic Magnets because they are electrically insulating. Hard Ferrite / Ceramic magnets composed of barium or strontium, were developed in the early 1960's as an alternative to the more expensive metallic magnets. This class of magnet is very hard, brittle and possesses lower energy characteristics compared to other magnetic materials. However, it is very popular and widely used in all industries, including Automotive, Aerospace, Military, Advertising, Design House, Electronic and Academic/R&D because of its excellent resistance to demagnetization, corrosion, and the advantageous pricing.
Ferrite Segment Magnet are manufactured by pressing, sintering, or injection molding. These magnets can be both anisotropic and isotropic. Anisotropic grades are oriented in the manufacturing direction and must be magnetized in the direction of orientation. Isotropic grades are not oriented and can be magnetized in any direction.

Ferrite Segment Magnet is a type of magnet made of ferrite material. Ferrite is a ceramic material with high magnetic permeability and good magnetic properties, so it is widely used in the manufacture of magnets.

Ferrite Segment Magnet have good magnetic permeability, stability and wear resistance, and can work in harsh environments such as high temperature, high pressure and strong magnetic field. They are widely used in electrical, electronic, automotive, medical, sensor, communication and aerospace fields.

Hard Ferrite magnet come in many different shapes and sizes, such as cylindrical, square, ring, curved, etc., which can be designed and manufactured according to different application needs. During the manufacturing process, the ferrite material is first sintered into the desired shape, then magnetized, and finally machined and treated to obtain the required precision and surface quality.

In conclusion,ferrite Segment Magnet is an excellent magnet material with broad application and market prospects.
