Magnetic Materials

The magnetic ferrite powder are suitable for producing different grades of hard ferrite magnets by wet pressing or dry pressing. We supply the magnetic ferrite powders in three forms: Granular powder (6-12mm), coarse powder (3-6um), fine powder (0.75-1.05um) according to the needs of clients. The magnetic ferrite powder can be classified as isotropic magnetic ferrite powder and anisotropic magnetic ferrite powder. Anisotropic magnetic ferrite powder has better orientability.

AlNiCo, SmCo, Ferrite magnets and Rubber magnets

Rubber Magnets are available in the form of rolls, custom cut sheets,Die-Cuts,and are often used in the applications as manufacturing display boards, price cards, road signs, posters, and refrigerator decorations.

Magnetic rammed safe pliers L325×W90×H75 N.W.:190g Hang Weight:2.5Kg When you are ramming, you can use it to fetch iron/steel accessories. It is used to protect you from injuring and improve your work efficiency.

SmCo magnet is mainly made of rare-earth Samarium,Cobalt and other metal elements.It possesses such advantages as folloing :higher magnetic properities,ourstanding thermal stability and higher working temperature(Max working temperature reaches 350ºC).Besides,SmCo magnet doesn’t need to be coated due to its excellent corrosion resistance.SmCo magnet is widely used in computer disc drives,sensors,traveling wave tubes,linear actuators,satellite systerms,radar,magnetic coupling,pump&valve and so on.

1) Nd2Fe14B is made of metal neodymium, iron, boron and other microelements. It is the third generation of magnet material exploited in the 1980s, which is called “ The king of magnet ” for its highest magnetic energy product. It is divided into Sintered NdFeB and Bonded NdFeB according to the different processing technique. The shapes of the products include square ( length, width: 0.8mm-100mm, the length of magnet’s charging direction: 0.8mm-50mm ), round and ring ( outer diameter: 1.0mm-150mm, inner diameter: 1.0mm-45mm, height: 0.8mm-34mm ). We can also produce segment and arc, sphere and abnormity. Because NdFeB is weak in causticityproof, its surface must be coated. According to the customers’ requirements, the coating can be gold, zinc, nickel or epoxy resin.

We are Chinese exporters of ferrite magnets and other type of magnet materials. Please kindly contact us.

SmCo is a high-capacity permanent magnet made from Sm, Co, Fe and other trace metal elements. Besides a max working temperature of 300 degree, it has remarkable resistance against corrosion and oxidation. Hence, it may be used in aeronautic and space industries among others.
