Ndfeb permanent magnet has good mechanical performance and high energy density, which is conducive to the lightweight, thin, small or ultra-miniaturization of magnetic components.
Nd-fe-b appear not only makes the electroacoustic motor, instruments and meters, magnetization of the magnetic separation, medical apparatus and instruments and devices to miniaturization, high frequency, high performance, low loss, low noise, direction, and with the characteristics of energy conservation and environmental protection to expand its application from the traditional field to the new energy cars, wind turbines, energy-efficient appliances and aerospace and other emerging areas.
Before the 1990s, the global ndfeb permanent magnet production enterprises mainly concentrated in Japan, the United States, Europe and other countries or regions, among which Japan was the largest producer of ndfeb permanent magnet material in the world at that time, accounting for more than half of the global total output.
With the increase of production cost in developed countries, the demand of downstream industry for ndfeb in China continues to grow and the competitiveness of its products improves. The internationally renowned manufacturers of ndfeb in the United States, Europe and Japan have taken joint ventures or established processing bases to transfer to China, driving the rapid development of local production enterprises.
In 2001, China's production of ndfeb reached 6,500 tons, overtaking Japan as the world's largest permanent magnet production base.
At present, the global production of ndfeb permanent magnet material is mainly concentrated in China and Japan, foreign ndfeb manufacturers mainly include Hitachi metal, shin-yue chemical and Germany VAC, domestic manufacturers mainly include zhongke sanhuan, ningbo yunsheng, yingluo hua, zhenghai magnetic material, antai technology, earth bear and so on.
Japan is the largest producer of ndfeb outside of China, Hitachi metal, shin-yue chemical and other enterprises occupy 48% of the global market share of high-performance ndfeb, among which Hitachi metal as the pioneer of sintered ndfeb permanent magnet material industry, is the world's largest producer of high-performance ndfeb.
VAC is also dedicated to the production of high-performance ndfeb products, with a global market share of about 2%.
For a long time, China's sintered ndfeb manufacturers mostly produce low-end products, facing greater market competition pressure.
In recent years, the energy conservation and environmental protection, new energy vehicles, information technology and high-end equipment for the development of strategic emerging industry, driven by some domestic enterprises continuously introducing advanced foreign ndfeb permanent magnet production technology, equipment and management experience, funding to carry out independent research and development, promote the fast increase of ndfeb manufacturing technology in China.
According to the new thought world industry research center announced the 2018-2023 Chinese depth of ndfeb industry market research and the development tendency prediction research report, according to a report in 2016 and 2018, global demand for high-performance nd-fe-b average annual compound growth rate will reach 19%, among them, the new energy vehicles drive motor, automobile micromotor (EPS), frequency conversion air conditioning, robots and energy-saving elevator, etc will become the important driving force of growth.
China has become the world's largest producer and consumer of ndfeb permanent magnet materials.
From the perspective of product varieties, the grade and quality of ndfeb permanent magnet products in China have been significantly improved. Taking N series as an example, from the initial production of medium and low grade products below N40 to the production of high brand N45 -- N52 products.
At present, high, medium and low levels of product specifications complete, production equipment has gradually realized the domestic, product performance gradually reached the advanced level of foreign.
In 2013, China's production of ndfeb reached 94,000 tons, accounting for more than 85% of the world's total production.
According to xinsi industry researcher, over the past decade, the global production of ndfeb has been growing rapidly. In 2013, the global production of ndfeb reached about 110,000 tons, among which, the production of high-performance ndfeb was about 42,800 tons, with a year-on-year growth of 16.56%, accounting for more than 5 percent of the total production of ndfeb.
With the global construction of low-carbon economy, energy conservation and environmental protection society, new energy vehicles, energy-saving home appliances, wind power, national defense and other emerging industries began to rise gradually, the demand of ndfeb continues to appear a new growth point.
Due to high performance ndfeb industry barriers, production cycle is slow, the next few years, high performance ndfeb will appear in short supply.
