Ndfeb magnetic material, as the latest result of the development of rare earth permanent magnet materials, because of their excellent magnetic known as & other; The king of magnetic & throughout; 。 Ndfeb magnetic material is neodymium, an alloy of iron oxide, etc. Also called magnetic steel. Ndfeb has a very high magnetic energy product and JiaoLi, at the same time, the advantages of high energy density makes the ndfeb permanent magnet material in modern industry and the wide application of electronic technology, so that the instruments and meters, electronic motor, magnetization of the magnetic separation equipment miniaturization, lightweight, thin become possible. Advantage: strong magnetic force, high cost performance, widely used, etc. Weakness: the fragile, so we need to pay attention to in use, in accordance with the normal usage. The third generation of rare earth permanent magnet ndfeb is of permanent magnets with the strongest performance in contemporary magnet, its main raw material with rare earth metal neodymium - 29% 32. Iron 63 5% metal elements. 95 - 68. Non-metallic element boron 1 65%. 1 - 1. A small amount of dysprosium adding 0 2%. 6 - 1. Niobium 0 2%. 3 - 0. Aluminum 0 5%. 3 - 0. 0 5% copper. 05 - 0. The elements such as 15%. Ndfeb permanent magnet material is based on intermetallic compounds RE2FE14B permanent magnetic material. Main ingredients for rare earth ( 卢比) , iron ( Fe) , boron ( B) 。 The rare earth ND for different performance available parts of dysprosium ( Dy) , praseodymium ( Pr) Other rare earth metals replace, iron can also be cobalt ( Co) , aluminum ( Al) And other metal parts to replace, the content of boron is small, but to form a square crystal structure between the metal compounds play an important role, make the compound with high saturation magnetization, high uniaxial anisotropy and high Curie temperature. Technological process: ingredients & rarr; Smelting tableting/sling with & rarr; Milling & rarr; Molding & rarr; Sintering tempering & rarr; Magnetic detection & rarr; Grinding & rarr; Pin cutting processing & rarr; Electroplating & rarr; The finished product. The ingredients are the foundation, sintering tempering is the key. Ndfeb magnet blank production tools and performance testing tools: a melting furnace, jilt belt furnace, a broken machine, jet mill, pressing molding machine, vacuum packaging machine, such as static pressure machine, sintering furnace, vacuum heat treatment furnace, magnetic tester, gauss meter. Ndfeb magnet machining tools: centerless grinding, rolling machine, double side grinding, flat grinding, slicing machine, double-sided grinding, wire cutting, special-shaped grinding, etc. Ndfeb strong magnet manufacturers network is a professional engaged in magnetic materials research and development, production, sales for the integration of high-tech enterprises. If there are any ndfeb magnetic material procurement requirements can call the hotline customer service.
