Ferrite materials, etc. Due to demand for cars and computers with high-grade magnets increases, the proportion of high-grade ferrite China will increase rapidly. Expected Tenth Five-Year period Y30H-1 series of high-end products will be increasing the proportion of about 40% in 2000 over 2005, 60% (about 126,000 tons) speaker magnets Which deal, Y30H-2 or more series of high-end brand product yield can reach about 10 percent (about 21,300 tons), the proportion of total exports increased to more than 50%. Magnetic material, commonly referred to as a magnetic material refers to a ferromagnetic material it is old and uses a very wide range of functional materials Which speaker inexpensive magnets, and magnetic substance as early as 3,000 years ago been recognized and applied, such as China Ancient natural magnet as a compass. Modern magnetic materials have been widely used in our lives, such as the permanent magnet material is used as a motor, transformer core material is applied as a magneto-optical memory used by the speaker magnet where good, computer floppy disks and other magnetic recording. Said speaker magnets, magnetic materials and information technology, automation, mechatronics, defense, national economy is closely related to information on all aspects of the big bits. And generally it believed that a magnetic material is defined by excessive elemental iron, cobalt, nickel and alloys capable of directly or indirectly generate a magnetic substance. Magnetized magnetic material according to the ease of demagnetization can be divided into soft and hard magnetic material. Easily removed after the magnetization of the magnetic substance called soft magnetic material, not easy to go to a magnetic substance called hard magnetic material. Generally soft magnetic remanence small, hard magnetic remanence bigger. Which is good service speaker magnets, magnetic new Xin Tong, speaker magnet provided by the Dongguan City, Tong Xin magnetic Limited.
