How about the functions of Sintered NdFeB magnets?

　　The Sintered NdFeB magnets, also called as the latest results of the development of rare earth permanent magnet material, due to its excellent magnetic properties, known as "Magneto". This is the product of research and development in the national 863 high-tech projects. Sintered NdFeB magnets with high energy product and coercivity force, at the same time, the advantages of high energy density of the Sintered NdFeB magnets permanent magnet material widely used in modern industrial, electronics and medical industries, so that the instrumentation, electric acoustic motors, magnetic magnetization, medical devices, medical equipment, and other equipment miniaturized, lightweight, thin as possible. The NdFeB magnet advantage of cost-effective, with good mechanical properties; deficiencies that the Curie temperature and low temperature characteristics and the easy chalking corrosion, so by adjusting its chemical composition and surface treatment approach must is improved, in order to achieve the requirements of practical application.

　　Nd-Fe-B permanent magnet is divided into the sintered Sintered NdFeB magnets two bonded NdFeB all directions have a magnetic, corrosion-resistant; Sintered NdFeB magnets surface to be corrosive coating, generally plated zinc, nickel, green zinc environmental nickel, nickel-copper, nickel, environmentally friendly nickel-copper and nickel. The sintered NdFeB generally axial magnetization, with radial magnetization according to the needs of the working face.

　　Chemical composition:

　　RE2FE14B based permanent magnet material Sintered NdFeB magnets materials based on intermetallic compounds. The main component for the rare earth (RE), iron (FE), boron (B). Wherein the rare earth ND in order to obtain different properties of the available part of dysprosium (Dy), praseodymium (Pr), and other rare earth metal substitution, iron can also be cobalt (Co), aluminum (Al) and other metal parts replacement, the boron content is small, but Quedui tetragonal crystal structure intermetallic compound plays an important role, so that the compound has a high saturation magnetization, high uniaxial anisotropy and a high Curie temperature is formed.
