Magnet role in our modern society can not be ignored in many industries are now using the magnets, which are very common in our use of them are able to bring a lot of benefits for us. So for this product which we need to have a good understanding, after the completion of these we can understand the use of magnets in Dongguan have a better understanding. When we will feel the effects in our industry in the use of magnets, these are what we can see and feel. 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. Preparation of sintered NdFeB permanent magnet materials, the most important thing is to select a magnet alloy elements, which directly determines the performance of the product is good or bad. But the high-temperature magnets, sintering process is also extremely important, different NdFeB sintered preparation 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. Suction magnet to be adjusted according to the experiment door to finalize a certain value. Ca is relatively low wafer yield magnets, so its addition amount should be 1.4 to 1.5 times the theoretical equivalent to the calculated 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.
