custom neodymium magnet












Analysts declare that plate of neodymium magnet rises sharply mainly because of promotion of fundamentals --- four specific reasons as follows:
1. Regulation of Subsidy Funds for National IOT Development and Rare Earth Industry, has currently published by Ministry of Industry and Information Technology and Ministry of Finance, which will provide financial support to mining regulation and high-end application of rare earth and also will give disposable rewards to those rare earth mining businesses which have been approved by environmental review. Insiders proclaim that national regulation for rare earth mining and rewards to mining and smelting business approved by environmental review will heavily strike domestic illegal business and benefit for industry integration.
2. New energy automobile promotes sharp growth of permanent magnet industry. New energy automobile, covering 30% of demand of neodymium magnets, will boom by national policies. Although its scale expansion needs more mature technology, domestic new energy cars will have a growth under the circumstances of rapid development of new energy cars, with long-term investment value. In the future, demand of NdFeB will exceed 30%.
3. The stable growth of wind power equipment boosts permanent magnet industry. Wind power equipments, occupying about 30% of demand of neodymium iron boron magnets, now have been obviously impacted by policies. Also, under the influence of upgrading consumption in short term, it will keep fast growth, stably promoting the demand of permanent magnet industry.
4. New high-end application of neodymium magnet emerges in an endless stream, of which fields of automotive electronics and robots have the biggest potential. With the further development of electronics, carts will develop and become large personal mobile internet terminal, and its demand of NdFeB will keep fast growth. It is expected that the four biggest fields of rare earth permanent magnets (micro electric, EPS, intelligent start and shutdown system, electric cars driving motors) will demand more than 24 thousand tons of NdFeB. Besides, with the development of global robot industry, industrial robots, professional service robot and household robot will demand more than 9 thousand tons by 2016.

As for concept stock, first recommends wind power equipment and Magnet Material. Second, due to the decline of MQ magnet powder, bonded NdFeB will take place of ferrite magnet in car and air-conditioner fields.
