Ferrite magnet

Ferrite

Ferrite magnet is a permanent magnet mainly made of SrO or BaO and Fe2O3 as raw materials. In addition to strong anti-demagnetization performance, this magnetic material also has the advantage of low cost. Ferrite magnets are hard and brittle, and require special machining processes. Our company mainly manufactures them through ceramic technology. Because ferrite magnets have good temperature resistance, low price, and moderate performance, they have become the most widely used magnets. Wide range of permanent magnets.

Production methods

Ferrite magnets are divided into two types: isotropic and anisotropic, and the manufacturing method is mainly compression molding. Our production equipment is all imported from Japan, with high processing precision, so that the product life is longer and the dynamic balance is better. Due to the sophisticated production technology, it can provide customers with higher quality services.

Isotropic magnet

The so-called isotropic magnet has no orientation. It is formed by powder metallurgy with fine particles, but without any magnetic field arrangement. Restricted. But the disadvantage is that the magnetic flux density is weak, and some applications may not be able to meet the magnetic force requirements set by customers.

Anisotropic magnet
The so-called anisotropic magnet, just opposite to the isotropic magnet, has orientation. It is made of fine powder when forming, and the arrangement of the high-voltage magnetic field is used to make the magnetic field a fixed axial or radial direction. After the magnet is completed , can only be magnetized according to the arrangement of the magnetic field during molding, and the magnetization direction that has been fixed cannot be changed. The advantages are strong magnetic force and high coercive force, which is the mainstream of the ferrite magnet market.

Sintered ferrite permanent magnet material is an important material for manufacturing motors of various parts of automobiles. With the continuous development of automobile technology, various functions of automobiles are gradually improved, and the price of rare earth raw materials has risen sharply in recent years. Due to the low cost of ferrite, the amount of ferrite used It will also be greatly improved, and there will be broader application fields and development prospects.
