China's NdFeB Output Accounts For 40% Of The World Total

Rare earth permanent magnet materials are alloys formed from rare earth metals and transition group metals. This kind of permanent magnet materials produced through a certain process are highly magnetic and can stay highly magnetic for a long time. This kind of materials are now divided into the first generation (RECo5), the second generation (RE2TMl7) and the third generation of rare earth permanent magnet materials (NdFeB).

The emergence of NdFeB and its growing applications in the electronic field has set off a wave of NdFeB electroplating in the electronic electroplating industry. This is because that NdFeB is one of the important basic materials for electronic information products, and is closely related to many electronic information products. With the popularization of communications devices such as computers, mobile phones and automobile telephones and the rapid development of energy-efficient vehicles, the demand for high-performance rare earth permanent magnet materials has grown rapidly around the world.

China has initially formed its own NdFeB production system with NdFeB output accounting for 40% of the world total. But its high-end NdFeB products lack international competitiveness. Rare earth permanent magnet materials, as an important part of new materials, have been widely applied in sectors such as energy, transportation, machinery, health care, IT and household appliances. Rare earth permanent magnet products are related to many sectors of national economy and their output and consumption has become an important measurement of a country's comprehensive strength and national economic development level.

As the third generation of rare earth permanent magnet material, NdFeB is highly cost-effective, so in recent years, it has gained sustained and rapid development in terms of scientific research, production and applications. The development of knowledge economy represented by information technology has continuously brought new opportunities for functional materials such as rare earth permanent magnet NdFeB, which opens up broad prospects for the NdFeB industry. Initially, NdFeB was mainly applied in voice coil motors for computer disk drives, nuclear magnetic resonance imaging (MRI) equipment, and a variety of audio and video equipment, microwave communications equipment, magnetic machinery (magnetic pumps, magnetic valves), and household appliances. But with the continuous improvement of its performance, NdFeB has found new applications in recent years. For example, due to its great demand for NdFeB, the magnetically levitated trains under development will surpass all other sectors in terms of NdFeB consumption.

NdFeB has poor oxidation resistance because of its large iron content, so surface treatment of NdFeB magnets has been carried out in many occasions. The most widely-used surface treatment method is electroplating. Therefore, the NdFeB electroplating technology has become a new and popular new technology in the electronic electroplating industry.
