Hast Sintered NdFeB Magnet-Low Weight lost Magnet

Due to superior performance, Sintered NdFeB Magnet is widely applied to many fields since invention; not only to industry, but also to daily life. It is the backbone of the permanent magnet industry now. However the traditional Sintered Ndfeb Magnet is easy to get rusty if there is no plating. This disadvantage restricts the scope of application of Sintered NdFeB Magnet as well. In order to improve this, Hast Sintered Ndfeb Magnet (also called low weight loss magnet) with high corrosion resistance is invented.


The raw material of Sintered NdFeB Magnet contains large amounts of neodymium and iron; so the performance of antioxidant is very poor. Although many plating you can choose (NiCuNi, Zn, black epoxy, Ag, Au etc.) and past salt spray test, it will peel off under extremely harsh environment. Two methods are mainly used to test the speed of oxidation corrosion: weight gain and weight loss; namely, by measuring the increase / reduction of the magnet quality. The principle of Hast Sintered Ndfeb Magnet (also called low weight loss magnet) is to increase the corrosion resistance and reduce the weight loss by controlling the process of raw material production, changing raw earth composition and microstructure. The Hast magnet is mainly used for motors, pumps, wind generators etc.
