Dongyang Changsong Magnetic Materials Co., Ltd. is a professional ferrite manufacturer. The company’s products mainly include ring, square, round and other series. In order to meet the needs of various industries in the national economy for magnetic materials, especially permanent ferrite The growing demand, high-performance products and other series of products, are working hard to develop.
At the same time, we can produce and meet the special models, specifications, sizes and special requirements of different users of permanent ferrite components. Ferrite is a metal oxide with ferromagnetism. In terms of electrical characteristics, ferrite The resistivity is much larger than that of metal and alloy magnetic materials, and it also has higher dielectric properties. The magnetic properties of ferrites are also expressed in high magnetic permeability at high frequencies. Therefore, ferrites have become high A non-metallic magnetic material that is widely used in the field of low frequency and weak electricity. Because the magnetic energy stored in the unit volume of ferrite is low, the saturation magnetization is also low (usually only 1/3 to 1/5 of pure iron), which limits it Applications in the low-frequency high-power and high-power fields that require high magnetic energy density.
Permanent magnet ferrite is a kind of compound with uniaxial anisotropy hexagonal structure. It is mainly barium, strontium, lead three ferrites and their composite solid solutions. There are homosexual magnetism and heterogeneous magnetism. Because of this type of iron After the external magnetization field disappears, the ferrite material can still retain a strong and constant remanence for a long time, and can be used to generate a constant and stable magnetic field in the external space. It has a wide range of applications, such as: in all kinds of electric meters, power generation Used as permanent magnets in phones, telephones, speakers, televisions and microwave devices
