DESCRIPTION

NdFeB, in short, is a kind of magnet, and we usually see the magnet is different, because of its excellent magnetic properties and is called "magnetic king." NdFeB contains a large number of rare earth elements neodymium, as well as iron and boron, the characteristics of hard and brittle. Since the surface is easily oxidized, NdFeB must be surface-treated. Surface chemical passivation is a good solution. NdFeB as rare earth permanent magnet material with a high magnetic energy product and coercivity, while the advantages of high energy density NdFeB permanent magnet materials in modern industrial and electronic technology has been widely used, so that the instrument Instrument, electro-acoustic motor, magnetic separation and other equipment, magnetic miniaturization, lightweight, thin as possible. Neodymium iron boron has the advantage of cost-effective, with good mechanical properties; lack of work is low temperature, poor temperature characteristics, and easy to powder corrosion, it must be adjusted by chemical composition and surface treatment to be improved in order to Meet the practical application requirements. NdFeB has a very high energy product and force, while the advantages of high energy density NdFeB permanent magnet materials in modern industrial and electronic technology has been widely used, so that instrumentation, electro-acoustic motor, magnetic separation magnetization Equipment such as miniaturization, lightweight, thin possible.
