Ferrite magnets is a ferromagnetic metal oxide. On electrical properties, the resistivity of the ferrite than metal, alloy magnetic material is much greater, but also a higher dielectric properties. Magnetic ferrite can also have a high performance magnetic permeability at high frequencies. Thus, a wide range of high-frequency ferrite has become weak areas of use of non-metallic material. Belonging to the non-metallic magnetic materials Zhongshan speaker magnet, is iron oxide and one or more metal oxides other composite oxide (positive or ferrite). 800-1000 gauss magnetic usually, often used in speakers, speakers and other equipment. As a third-generation NdFeB rare earth permanent magnet materials with high performance, which are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the development of information technology as the representative of the knowledge-based economy wholesale motor magnet, NdFeB rare earth permanent magnet to industry and other functional materials continue to bring new uses, which brings a broader market prospects for NdFeB industry. NdFeB magnets are tetragonal crystals of neodymium, iron and boron (Nd2Fe14B) formation. This magnetic energy product (BHmax) greater than samarium cobalt magnets, then the world's largest energy product material. [24] Later, Sumitomo Special Metals successful development of powder metallurgy method (powder metallurgy process) bags magnets price, GM's successful development Churning melting (melt-spinning process), capable of producing NdFeB magnets. [25] It is now the strongest magnetic magnets of the permanent magnets, rare earth magnets is the most frequently used (rare earth magnet), is widely used in electronic products, such as a hard disk, mobile phones, headsets and battery powered tools and the like.
