Ferrite Magnets
Ferrite permanent magnet materials, is a manufacture of powder metallurgy method, mainly divided into material barium (Ba) and strontium (Sr) two kinds of material, and divided into two categories, the anisotropic and isotropic. Because of its raw materials do not contain rare earth elements of cobalt, nickel and other precious metals. And its production process is relatively simple, so its price is cheap. In addition, because of its moderate performance, coercive force is bigger, the strong ability of resistance to demagnetization, therefore, ferrite magnets, is currently the most widely used of a permanent magnet material. Ferrite highest working temperature can reach 250 degrees Celsius, more hard and brittle, diamond cutting tools, such as sand available alloy mold a molding processing just beginning.
