NdFeB magnet NdFeB, as a result of the latest development of rare earth permanent magnet material, because of its excellent magnetic properties and are called "Magneto." NdFeB magnetic material is an alloy of praseodymium neodymium metal, such as iron and boron. Also known as magnet. NdFeB has high energy product and coercive force, while the advantages of high energy density make NdFeB been widely used in modern industrial and electronic technology, so that the instrumentation, electro-acoustic motors, magnetic magnetization and other equipment of small, lightweight, thin as possible. NdFeB advantage is cost-effective, with good mechanical properties; downside is that the low point of the Curie temperature, the temperature characteristics are poor, and easy-powder corrosion, must be improved so that by adjusting the chemical composition and surface treatment method adopted in order to achieve practical application. * What is deposit orebodies · surrounding rock deposit means is formed by geological processes in the earth's crust. Geobodies by the Mineral Resources and associated geological elements of composition, the useful mineral resources must be large ball mill in certain economic technique, in terms of quality and volume two areas have exploitation value. Ore ore body is composed of geologic body has a special ball shape, size and occurrence of. Mineral mine is an open object ball is the main part of the deposit. A deposit usually includes several or even hundreds of minerals. Wall rock surrounding the ore body is surrounded by a variety of mineral rocks, the boundaries between it and the ore body is sometimes obvious, sometimes the transition is unclear, general stores bits to determine the ore body.
