Overview of NdFeB magnets industry

　　Neodymium magnets have the advantages of small volume, light weight and strong magnetic characteristics, has by far the best cost performance among permanent magnets. It is expected that in the next 20-30 years, magnetic materials will not turn up to replace neodymium magnets. The main raw material for the production of Nd-Fe-B permanent magnets' materials has neodymium metal, pure iron, iron alloy and other additives.

　　The core technology of NdFeB magnets industry is mainly reflected in the manufacturing process, embodied in the aspect of the product uniformity, consistency, processing quality, coating quality.

　　NdFeB magnets industry is a industry with strong patent, only after gaining the patent license and payubg the patent fee, ut can be sold in the areas of patent magnet monomer or equipped with magnet components. NdFeB Magnets patent is a patent package, although the main patent has been close to maturity, but there are many auxiliary patent without protection period, still can be protected for several years. In China, manufacturing, sale and use of NdFeB magnet does not involve any patent problems, but if not obtain patent licenses, its products cannot be exported to the patent coverage area, otherwise constitute infringement.
