Magnetic material refers to the transition elements of iron, cobalt, nickel and their alloys can directly or indirectly produce magnetic materials. Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the difficulty of demagnetization after magnetization. The material which magnetization Easy to loss is called soft magnetic materials, the material which magnetizationit is not easy to loss is called permanent magnet.
It also can be divided into three categories: ferrite magnetic materials, rare earth magnetic materials and other magnetic materials.
Global magnetic material industry market analysis
Due to their unique properties, magnetic materials are suitable for various automotive, electronic and electrical products and their applications. In 2016, the global market size of magnetic materials industry has reached usd 32.15 billion. As of 2017, the global magnetic material industry market size reached 34.86 billion us dollars, and it is predicted that the global magnetic material industry market size will reach 51.72 billion us dollars in 2020, CAGR=8.2%.
Magnetic materials are used in a wide range of applications, including electric motors, consumer electronics, generators, transportation, medical equipment and so on. Electric motors and consumer electronics were the biggest applications, accounting for 31.2% and 20.3%, respectively, in 2017. It is predicted that the application proportion will be 31.3% and 20.4% respectively in 2020.
According to the data, both permanent ferrite and soft ferrite are in stable state in recent years. Based on the analysis of the output of permanent ferrite magnet and soft ferrite magnet in China, the demand for magnetic materials has not increased significantly in the past five years due to the economic recession, declining demand and the trend of miniaturization and thinness of products.
In recent years, the transfer of international manufacturing industry, rare earth raw materials prices high, high labor costs. Under the influence of the above factors, the global ndfeb industry has undergone major changes in the international landscape, China has become the world's largest producer of ndfeb. According to the ministry data statistics, in 2018, new energy vehicles, energy-efficient appliances, electric tools, industrial robots and other industries for rare earth permanent magnet materials industry development provides an important support, quality improving industry development, product production steady growth, the key enterprise benefit to maintain good posture, grain boundary diffusion and other advanced technology to further promote and expand the new application fields such as high speed railway traction motor.
As of 2018, China's production of rare earth permanent magnetic materials has reached 164,500 tons. Among them, sintered ndfeb rough production of about 155,000 tons, a year-on-year growth of 5%. The output of bonded ndfeb reached 0.7 million tons, up 5% year-on-year. Samarium cobalt magnets produced 25, 000 tonnes, unchanged from the same period last year.
With the continuous development of emerging application markets, such as automotive electronics, LEDTV, LED lighting, EMC, 4C(computer, communications, radio and television, content services) integration and 4G, 5G communications, smart grid, Internet of things, new energy vehicles and other emerging markets, will provide more development opportunities for the development of China's magnetic materials industry.
