Competitive Landscape Analysis of Ferrite Permanent Magnet Industry
1. Major companies
Ferrite permanent magnet products mainly include 4 series, 6 series, 9 series, 12 series, 15 series, etc. TDK has been able to mass produce 15 series high-end magnetic materials, but China’s 15 series products are still in the research and development stage, and 9 series and above The proportion of products is relatively low, and high-end products rely on imports. With the technological progress and scale expansion of China’s leading enterprises, my country is gradually realizing import substitution in some high-end products. At present, the highest level of development and production of permanent magnet ferrite products in the world belongs to Japan’s TDK, with obvious technical advantages. Longci Technology is the leader in the production of high-performance ferrite permanent magnet materials in China. The scale of permanent magnet ferrite wet-pressed magnetic tiles ranks second in China and top five in the world.
2. Domestic market share
From the perspective of the permanent magnet ferrite production pattern of leading enterprises in my country, the Hengdian East Magnet magnetic material industry has an annual output of 200,000 tons of ferrite pre-sintered material, 160,000 tons of permanent magnet ferrite, 40,000 tons of soft ferrite, 2 With a production capacity of 10,000 tons of plastic magnets, it is the largest ferrite magnetic material manufacturer in China; according to statistics, in 2021, Hengdian East Magnet’s permanent magnet ferrite output will be 133,700 tons, accounting for 25.9% of the country’s total output, followed by North Mine Technology, Longci Technology and Sinosteel Tianyuan accounted for 10.9%, 6% and 1.9% of the output respectively, and the output of other enterprises accounted for 55.3%.
Prospects of permanent magnet ferrite industry
Overall, the development of my country’s permanent magnet ferrite material industry is relatively stable, but changes in supply and demand in the international peripheral market and price fluctuations in raw materials will also have a certain impact on industrial development. At present, the production of permanent magnet ferrite in my country is quite mature and developed, but most of the magnetic material products in my country are concentrated in the middle and low level. Therefore, more scientific research workers are needed to break through the technical blockade of “stuck necks” abroad, so that my country can change from a “big manufacturing country” of permanent magnet ferrite products to a “big manufacturing country of intelligence”. In this paper, the main manufacturing methods of permanent ferrite have their own advantages and disadvantages, and the methods to improve their magnetic properties are also explained from three aspects, including the changes in the raw materials for preparing permanent ferrite products in the future. Any breakthrough in any link will bring great benefits to the industry. Bring great progress and far-reaching influence.
In the future, the technical development direction of China’s permanent magnet ferrite products will be La-Co, La-Zn and magnetic powder particle size distribution control technology, high orientation technology, and special process technology. Should develop:
(1) SrM magnets with higher magnetic properties;
(2) Permanent ferrite materials with higher temperature stability;
(3) Smaller and thinner permanent ferrite magnets;
(4) Permanent magnet ferrite products with high-precision dimensions and geometric tolerances;
(5) Diversified magnetization methods (multi-pole anisotropic radial magnetization, two-stage anisotropic radial magnetization, radiation orientation anisotropy) permanent magnet ferrite products;
(6) Permanent magnet ferrite products with wider application fields.
The growth of the industry in the future depends on the promotion and popularization of new applications; the application of high-performance special fields is the point of profit growth; the independent intellectual property rights and technology development and innovation of enterprises in the future should also receive more attention to improve the technological content and additional value of products. value. We must pay attention to technological development and innovation, make new products, new technologies, and new processes organically combined, and put the improvement of the technological content of magnetic products in the first place. At the same time, technology and trade should be combined. Only by walking on two legs can science and technology be transformed into productivity as soon as possible, and products with high-tech content and high added value can participate in international competition.
