Problems in China's Soft Magnetic Materials Industry
Looking at the development of magnetic materials in China for so many years, such achievements are mainly due to the expansion of production scale and investment in production hardware. There is still a certain gap between the technical performance level of mass production of magnetic products and the international advanced level. The prices of medium- and low-end products compete on the edge of no profit, disorderly and without rules. The company has not developed enough magnetic products for high-tech applications and cannot first occupy new application areas. In the domestic equipment manufacturing industry, new and innovative magnetic products have not been updated and innovated, and high-grade material manufacturing equipment has been introduced. The gap between China's magnetic materials and foreign countries is specifically expressed in the following aspects: (1) There is a gap in the level of product quality The research level of China's soft magnetic materials has made very significant progress in recent years, and has greatly improved compared with international counterparts. This is mainly related to the development and competition objectives of each company with advanced counterparts. Table 1 shows the results of Tiantong's soft magnetic materials compared with international counterparts. The level of China's soft magnetic materials has been somewhat improved, but many new material research and development achievements have not really translated into large-scale production, leading to a certain gap in the quality level of batch products. In addition to the material level, factors such as poor product consistency, poor appearance, lack of brand names, and lack of timely delivery have greatly constrained the rapid increase in the quality of magnetic materials in China. At present, the technical quality level of China's mass production of soft ferrites is not high, and the performance of power ferrites is equivalent to the PC30 and PC40 grades of TDK Corporation of Japan; the μ value of high permeability ferrites is approximately 7000~10000. Only very few units can stabilize PC44 grade power ferrites and high-permeability ferrites with a μ value of 10,000 or more in small batches. (2) The price difference shows from Figure 5 that the average export price of magnetic materials in China is about US$3.6/kg, while the average import price is about US$7/kg, and the difference in import and export of Chinese magnetic materials is too large. As far as the soft magnetic field is concerned, China’s products are very low in terms of the selling price in the international market, and large magnetic cores for household appliances, etc., sell for about 15,000 yuan per ton, and small cores for telecommunications use sell at around 3 per ton. About 10,000 yuan, only 1/2 to 1/3 of the price of similar products in Japan. In terms of Tieling Iron and Steel, China accounts for 77% of world production but only has 57% output value. The output value-to-output ratio is only 0.74, which is far less than Japan's 1.81 and Europe's 3.0. In addition to the reasons for sales channels, this has a direct bearing on factors such as low grades of products, poor consistency of performance, poor appearance, lack of brand names, and lack of timely delivery. Most soft magnetic companies in China have long-term production in low-grade products, affecting their own technological level and management level. On the other hand, low selling prices and low profitability have affected the expansion of reproduction, resulting in raw materials and energy resources. Waste, it is difficult to form a virtuous circle. Through the moderate development of China's high-grade soft ferrites, it is of great practical significance to improve the existing product structure, enhance competitiveness, expand the matching with transformers, inductors, etc., and export foreign exchange.
