Why are ndfeb magnets in the environment of high temperature demagnetization?

Dongguan kyokuto magnetic industry co. , LTD. , set research and development, production, sales for the integration of high-tech enterprises, specializing in the production of high-end aluminum nickel and cobalt, ndfeb, samarium cobalt, ferrite permanent magnet materials and their products. Ndfeb magnet demagnetization occur is in high temperature environment, which is by itself the physical structure of the resolution. General magnet magnetic field can occur, because the material itself with the electrons around the atoms in accordance with the direction of rotation must be, and then must be magnetic field force, and influence on surrounding related transactions occur. But electrons around the atoms in accordance with the established direction is surely temperature conditions, ndfeb magnets in different magnetic material can withstand temperatures are also different, in the case of too high temperature, the electronic will deviate from the original track, form the disorder phenomenon, magnetic material at this time the local magnetic field will be upset, and then presents the demagnetization phenomenon. Advantages of ndfeb magnets: sintered ndfeb magnet quality could be determined according to the magnet size, the shape of the ndfeb magnet is based on its use and make a different shape, different during the production process is also through many process, good quality of sintered ndfeb magnet tend to smooth, but also must be accuracy. So whether a qualified sintered ndfeb magnet, not only the function of the demand for qualified, scale and the control of the public servants directly affects its use. Guarantee scale directly depends on the processing power of the factory.
