New energy vehicles on the NdFeB industry to promote the role of great

There is no technical problem with producing NdFeB magnets for automotive motors

The requirements of the electric drive system for the drive system are high torque density, high reliability of operation and good torque control capability, thus requiring that NdFeB needs high energy product, high coercivity and high working temperature. Since the magnetic energy product and the coercive force are opposite to each other, a compromise solution is needed. N42 generally used for the grade of NdFeB magnets for automotive motors. By adding rare metal dysprosium, the working temperature can be raised to 400 degrees Celsius to meet the car requirements. After Europe and the United States, the domestic auto companies trial, the domestic NdFeB magnets meet the technical requirements, everything is ready, only orders. Hitachi Metals has worked with Japanese auto makers such as Toyota for years, and its high-performance neodymium-iron-boron magnets have been used and proven on the Prius. To domestic high-end NdFeB manufacturers, through cooperation with car manufacturers, motor manufacturers to develop, already have the production of automotive motor with NdFeB capabilities. Products have been domestic, Europe and the United States car manufacturers trial, technology and quality no problem. Although there is no order yet, domestic enterprises have already done a good job of mass production preparation. They can be described as "everything is ready and only owe the east wind."

New energy vehicles on the Neodymium Iron Boron demand is as follows:

HEV: Each car than the traditional car with NdFeB 3 kg or so;

EV: There are currently two technical solutions. One is the use of rare earth permanent magnet motor as an engine, each need to use more NdFeB 5-10 kg;

The other is the wheel drive, that is, into the wheel motor, so that if the two-wheel drive, each vehicle need to use more NdFeB 10-20 kg; 4-wheel drive, you need 20-40 kg NdFeB. This report uses a median scenario, that is, 10 kg of NdFeB for each EV.

Kearney predicts that the global HEV production will exceed 10 million by 2020, directly bringing the demand of NdFeB to 38,000 tons / year. According to Kearney, HEV production will account for 3% of global automotive production by 2010, and by 2020 HEV will account for 17% of global automotive production. Global car production is expected to reach 60 million units in 2010 and 75 million units in 2020. According to this projection, the global HEV production will reach 12,750,000 by 2020. Each HEV than the traditional car with NdFeB 3 kg, bringing NdFeB demand 38000 tons. Pure electric vehicles (EV) by 2020 more than 6 million worldwide, NdFeB needs 60,000 tons / year. Taken together, the world

Neodymium iron boron demand of 98,000 tons / year brought by new energy vehicles in the year. NdFeB car price of 70 US dollars / kg, according to 1 US dollars = 6.77 yuan calculation, the global neodymium iron boron market by the new energy vehicles in 2020 466 billion yuan.

The domestic number of new energy vehicles showed explosive growth. It is estimated that from 2010 to 2020, the number of new energy vehicles in China will increase from 20,000 to 5.26 million with a compound annual growth rate of 74%. Among them, HEV increased from 13,500 to 1.24 million with a compound annual growth rate of 57%; pure electric vehicle (EV) increased from 7,000 to 4.02 million with a CAGR of 89%. In 2020, the domestic market of NdFeB for electric vehicles will exceed 20 billion yuan. By 2020, the demand for NdFeB in China is 44,000 tons / year. NdFeB electric car with the price of about 70 US dollars / kg, according to 1 US dollars = 6.77 yuan conversion, by 2020, the domestic electric car with NdFeB market size of about 208 billion yuan.

New energy vehicles on the NdFeB industry to promote the role of great

Consider the demand of traditional NdFeB magnets. From 1996 to 2008, the global Nd-Fe-B industry increased from 900 million U.S. dollars to 3.6 billion U.S. dollars, with a CAGR of 12%. Optimistic about the industry is expected to maintain a 10% compound growth rate, by 2020, the traditional NdFeB market size of 11.6 billion US dollars, equivalent to 77.4 billion yuan. According to our forecasts, the demand for neodymium-iron-boron will only reach 46.6 billion yuan by 2020, accounting for 60% of the traditional demand. It can be said that the new energy vehicles in the future will be the most important NdFeB market.
