As is known to all, the third generation of rare earth ndfeb permanent magnet is contemporary magnet performance strong magnets, a wide application, it is the main raw material: metal, pure iron and boron neodymium iron alloy, in order to improve the coercive force can add metal dysprosium ( Sometimes adding aluminum, cobalt, praseodymium, dysprosium, terbium, gallium, etc. ) General expressions for the: RE2TM14B ( RE = Nd,公关,Dy TM =铁、Co) 。 Ndfeb material than how much of each item? 1, rare earth metal neodymium accounted for 29% 32. 5%; 2, metal iron accounted for 63. 95 - 68. 65%; 3, nonmetal elements boron for 1. 1 - 1. 2%; 4, a small amount of added dysprosium accounted for 0. 6 - 1. 2%; 5, niobium 0. 3 - 0. 5%), aluminum (0. 3 - 0. 5%; 6, copper accounted for 0. 05 - 0. 15% elements; How about the quality of these raw materials, will be directly related to magnetic ndfeb permanent magnets. Now many of the magnet manufacturer will also provide us with ndfeb strong magnet, but due to their different ways of production and processing, the proportion of the ingredients are still slightly different.
