Magnetic Powder > quenched NdFeB powder
quenched NdFeB powder
Guangzhou Dexing Magnets Co., Ltd. is a professional production of quenched NdFeB powder manufacturers, the current annual production capacity of 200 tons, is one of the the largest rapid quenching NdFeB powder manufacturers (domestic enterprises), the products in the domestic marketshare as high as 30%. Consistency of quality of our products, the magnetic properties of the leading domestic manufacturers, welcome domestic and foreign manufacturers for the production of bonded magnets contact us and establish long-term cooperative relationship.
Rapid quenched Nd-Fe-B permanent magnet alloy is one of the raw materials of bonded magnets. In recent years, the preparation of bonded NdFeB magnets extremely rapid development of technology and applications, the market is growing year by year. Quenched Nd-Fe-B alloy powder prepared is magnetically isotropic powder, the obtained bonded magnets is isotropic; each is hydrogen processing technology, also called the NdFeB powder prepared by the HDDR method anisotropic magnets prepared with this powder is anisotropic magnet.
The bonded magnet is a magnetic powder and a resin or polymer materials kneaded or magnetic particle cladding, and then with a molding method, injection molding method, extrusion method or rolling method, etc. will be prepared as the final size and shape, after curing sticky Results magnet. Because a certain amount of the binder to be contained in the bonded magnet, these binders are non-magnetic material, and the density of the bonded magnet is lower than the sintered magnet, so its magnetic properties were lower than the sintered magnet. But bonded magnets have many advantages, excellent mechanical properties; without machining precision the final size of the product; cyclic products of the preparation of complex shapes and extremely thin; continuous high volume automated production. Therefore in some areas to be widely applied.
Quenched magnetic powder can also be obtained by hot pressing the original alloy density, high-density magnets, it is isotropic. Then by thermal deformation suppress such high density magnet to obtain an anisotropic magnet, this magnet and the sintering density of the magnet and the magnetic equivalent, but bonded magnet should not include these two magnets.
