Brief Introduction Of Neodymium Iron NdFeB Magnet Small Knowledge

NdFeB magnet, which is currently found in the highest commercial performance of the magnet, known as the magnetic king, with a small size, light weight and strong magnetic characteristics, is by far the best cost performance of the magnet. Has a very high magnetic properties of its maximum magnetic energy product (BHmax) higher than ferrite (Ferrite) more than 10 times. Its own mechanical processing performance is also quite good. Operating temperature up to 200 degrees Celsius. And its texture is hard, stable performance, a very good price, so its application is extremely extensive. But because of its strong chemical activity, it must be its surface coating treatment. (Such as plating Zn, Ni, electrophoresis, passivation, etc.).

NdFeB magnet basic knowledge

NdFeB magnet can be divided into two kinds of bonded NdFeB and sintered NdFeB.

It is expected that in the next 20 to 30 years, there can be no substitute NdFeB magnet of magnetic materials appear. The main raw materials for the production of NdFeB magnet are metal neodymium, pure iron, boron iron alloy and other additives. NdFeB magnet industry's core technology is mainly reflected in the manufacturing process, embodied in its product uniformity, consistency, processing quality, coating quality and so on.

NdFeB magnet as the third generation of rare earth permanent magnetic materials, has a high cost performance, its widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the information technology as the representative of the knowledge economy The development of rare earth permanent magnet NdFeB industry and other functional materials continue to bring new uses, which for the NdFeB industry to bring a broader market prospects.
