In the 18th century and the emergence of artificial magnets, but higher magnetic material manufacturing process has become very slow, until the 1920s to produce aluminum, nickel and cobalt. According to the magnet manufacturers talk, that is sintered powder metallurgy method. Sintering is a method for the preparation of NdFeB the most important one, the current production of sintered NdFeB permanent magnet materials, compared with NdFeB permanent magnet materials prepared by other methods much more. And with the further expansion of its applications, and its annual production continues to rise. Sintering process gold NdFeB magnets Taizhou, the most important thing is to select the alloying elements, which directly determines the performance of the product is good or bad. However, the sintering process is also extremely important magnets, NdFeB permanent magnet materials prepared by different sintering process is completely different. The basic principle of the reduction of manufacturing NdFeB diffusion method is to use a metal Ca reduction Nd2O3, make it into a pure Nd. The reaction to which direction, depending on the size of the free energy of formation of Nd2O3 and CaO. According to the experiment to be adjusted, to finalize a certain value. Ca recovery rate is quite low, and thus should be added in an amount equivalent to 1.4 to 1.5 times the theoretical value. Preparation use reduction diffusion process NdFeB permanent magnet materials, the process is characterized by a lower cost of production, technology and the future of its milling powder metallurgy approach is consistent. Magnet permanent magnet in the market today state of development in the face of harsh competition in the market, the price of NdFeB magnets are easily overshadowed by the market in the form of these two years is not good, the development of a permanent magnet to magnet intense stage, all manufacturers face harsh production environment, had to be the bottom of the price war, due to the limited production capacity of these manufacturers, only a simple product processing methods are quality magnets, no own special product advantages, since a business to survival, the only way is to use the service to maintain the price with a manufacturer's survival, competition for orders.
