Magnetic materials are suitable for a wide range of automotive, electrical and electrical products and other applications due to their unique properties. In 2016, the global magnetic materials industry market has reached 32.15 billion US dollars. As of 2017, the global magnetic materials industry market reached US$34.86 billion, and the global magnetic materials industry market is expected to reach US$51.72 billion by 2020.
Magnetic materials are used in a wide range of applications, including electric motors, consumer electronics, generators, transportation, medical devices, and more. Motors and consumer electronics are the largest applications, accounting for 31.2% and 20.3% respectively in 2017. It is predicted that the proportion of applications in 2020 will be 31.3% and 20.4% respectively.
At present, the output of magnetic materials in various categories in China ranks first in the world, and it has established the status of the world's largest producer of magnetic materials and the center of magnetic materials industry.
In recent years, under the influence of multiple factors such as the shift of international manufacturing industry, high prices of rare earth raw materials and high labor costs, the international pattern of the global Neodymium industry has undergone major changes, and China has become the world's largest rare earth Neodymium. Producing countries. According to statistics from the Ministry of Industry and Information Technology, in 2018, new energy vehicles, energy-saving appliances, power tools, industrial robots and other industries have provided important support for the development of rare earth permanent magnet materials industry. The quality of industry development has been continuously improved, product output has grown steadily, and key enterprises have maintained good returns. Advanced technologies such as the situation and grain boundary diffusion have been further promoted, and new application fields such as traction motors for high-speed rail have been expanded.
According to statistics from the China Magnetic Materials Industry Market Prospect and Investment Strategic Planning Analysis Report released by the Prospective Industry Research Institute, the output of rare earth permanent magnet materials in China reached 164,500 tons by 2018. Among them, the output of sintered Neodymium rough was about 155,000 tons, an increase of 5%. The output of bonded Neodymium was 0.7 million tons, a year-on-year increase of 5%. The output of samarium cobalt magnets was 25,000 tons, which was the same as that of the same period last year.
With the development of emerging application markets, such as automotive electronics, LEDTV, LED lighting, EMC, 4C (computer, communications, broadcasting, content services) integration and 4G, 5G communications, smart grid, Internet of Things, new energy vehicles and other developments Emerging markets will provide more development opportunities for the development of China's magnetic materials industry.
