Ndfeb permanent magnet material is made by a certain technology, strong magnetic ndfeb permanent magnet materials and can maintain lasting. This material is now divided into the first generation ( RECo5) And the second generation ( RE2TMl7) And the third generation of rare earth permanent magnet ( 钕铁硼) 。 The emergence of ndfeb permanent magnet materials and its application in the field of electronic the rapid development of the electronic industry in an upsurge of ndfeb electroplating. This is because the ndfeb material is one of important basic materials in electronic products, is closely related to many electronic products. As the communications equipment such as computers, mobile phones, car phone popularization and the rapid development of fuel-efficient cars, the world of high performance rare-earth permanent magnetic material demand is growing rapidly. On the ndfeb production in our country has initially formed its own system, production has accounted for 40% of the total amount of the world, but the share, high-grade product has not yet formed strong strength, lack of international competitive ability, as an important part of new materials of rare earth permanent magnet materials, widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, its products cover many fields of national economy, its production and consumption has become a measure of a country comprehensive national strength and an important symbol of the national economy level of development. Summary as the third generation of rare earth permanent magnet material, has the very high cost performance, so in scientific research, production and application in recent years obtained the rapid development of. Represented by information technology in the development of knowledge economy, the function such as rare earth permanent magnet ndfeb industry material constantly bring new USES, this bring ndfeb industry more broad prospects. In ndfeb permanent magnet materials, at the beginning of the invention is mainly used in computer disk drives voice coil motor ( 单体氯乙烯) , nuclear magnetic resonance imaging ( MRI) As well as a variety of audio and video equipment, microwave communications, magnetic machinery ( Magnetic pump, magnetic valve) And home appliances. With the continuous improvement of its performance, in recent years there have been some new applications. For example, is now in the development of maglev train demand for ndfeb will make its use more than all the other areas. Ndfeb permanent magnet material containing a higher iron content, its oxidation resistance is poor, therefore used in many occasions, the permanent magnet on the surface treatment. And with the most is plating surface treatment solution. Therefore, ndfeb material of electroplating technology become the emerging in electronic electroplating and hot new technology.
