Ferrite magnets

General Information

Ferrite magnetCeramic magnets or ferrite magnets are sintered permanent magnets composed of barium or strontium carbonate, and iron oxide. This class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost. The sorts of hard ferrite magnets are manifold and complete. They are charcoal gray in color and usually appear in the forms of toroid, circular disk, square, bar, arc segment, blocks, rings, cylinders special magnets etc. The detail specifications are up to hundreds of kinds.

The corrosion resistance of Ferrite is considered excellent and no surface treatments are required. It can be used in temperatures up to 80 degrees C. However, Ferrite magnets may have a thin film of fine magnet powder on the surface and for clean, non-contaminated applications, some form of coating may be required. Standard parts include blocks, discs, rings & round bars in different dimensional specifications. Magnets are available in different shapes & sizes and can also be custom fabricated according to specifications & tolerances.

Ferrite magnets are very hard and brittle, and require specialized machining techniques. Moreover, they should be machined in an unmagnetized state. We are equipped to machine these materials to specifications. 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, although some degree of greater magnetic strength will be found in the pressing dimension, usually the shortest dimension.

Our main products includes: Hard ferrite arc or segment magnet, ring magnets, rectangular magnets, ferrite podwer etc. Which have the following advantages: high coercive force, high electric resistance, long-time stability, and economical price. Meanwhile, we can manufacture new tools according to the customers` demand. Recent years, we have been placing the emphasis on producing the high property magnets for the motors of automobiles and motorcycles. The characteristics of the products have kept in the leading level in China.

Ferrite magnet application

The permanent ferrite magnets have character of various applications, cheapness, etc. They are the basic functional materials in the electronic industry. They are widely used in very sort of motors, electro-acoustic, magnetic force machines, duplicators, magnetron fields, household apparatus, magnetic couplings, for sensing, loudspeakers, holding-magnet systems, crafts, magnetic therapy, novelties and toys.

Magnet for automobile industry is our most important product , we are the few manufacturers in china that design and produced Ferrite Radial-Oriented Multipole Magnetic ring, according to the automobile features, We currently provide magnetic ring with hundred of different specifications for starter motor and window-rolling motors satisfying different customers needs, which are the leading magnet in China.

High efficiency magnetic ring is the core part of permanent magnet synchronous motors, stepping motors and DC brush-less motors, these motors are widely used in automotive, computers, electrics, communications, office and school equipments, and household products.
