1. "Double carbon" accelerates the penetration of Nd-Fe-B permanent magnet, and new application fields emerge one after another
Sintered NdFeB is widely used in many fields. It can be said that motors are used in most fields that need electrical and mechanical energy conversion. Due to their high performance, low loss and small volume, permanent magnet motors can be applied to the field of medium and high-end small and medium-sized motors, and play a role in downstream terminals, including traditional vehicles, new energy vehicles, consumer electronics, clean energy, mobile communication, energy conservation, aviation and many other fields. The downstream demand is constantly changing. In the future, new energy vehicles will become the largest application field of high-tech Nd-Fe-B permanent magnet materials in the world. NdFeB continues to penetrate into more fields. At the beginning of the 21st century, NdFeB is mainly used in acoustics, servo motors and other fields. From 2005 to 2010, NdFeB rapidly penetrated into the field of hard disk VCM. After 2010, with the development of smart phones, the field of consumer electronics has been replaced; After 2014, the installed capacity of wind power has entered a period of rapid growth. In three years, the new energy vehicle industry has penetrated rapidly. Various performances can see the demand composition of Nd-Fe-B. In 2020, wind turbine is the largest application field of high-performance NdFeB. It is expected that new energy vehicles will replace wind turbines in 13 years
2. Attention should be paid to technological innovation in the future
Nd-Fe-B still has room for performance. Theoretically, rare earth permanent magnets are mass produced in industry, and their magnetic performance can reach up to 89% of the theoretical value. In recent years, leading manufacturers have been able to improve their performance to near 90% of the theoretical value. It is found that the medium heavy rare earth located at the grain boundary can better improve the coercivity, and the grain boundary penetration technology can change the dispersion of medium heavy rare earth. After sintering, the medium heavy rare earth elements are concentrated at the grain boundary to improve the coercivity; At this time, the doping proportion of medium and heavy rare earth can be greatly reduced, and the output of dysprosium and terbium can be reduced from 5-7% to 0.2-0.4%.
