Micro nano metal powder, a seemingly insignificant basic raw material, is now playing an increasingly important role in new industrial manufacturing, ranging from people’s daily necessities to sophisticated aerospace.
How to promote the development of the application field of micro nano metal powder new materials? Recently, a reporter from Securities Daily came to Jiangxi Yuean Advanced Materials Co.Ltd(688786) , a listed company in Dayu, Jiangxi Province, to find out.
China ultrafine carbonyl iron powder
can achieve 1.2 micron level
Jiangxi Yuean Advanced Materials Co.Ltd(688786) is a high-tech enterprise focusing on the field of micro nano metal powder new materials Jiangxi Yuean Advanced Materials Co.Ltd(688786) chairman Li shangkui introduced to the reporter of Securities Daily that in the field of powder metallurgy with the widest application range, carbonyl iron powder can not only improve the yield and strength of products, but also prolong the service life of products, so it is considered to be one of the best additives.
\u3000\u3000 “In terms of electronic power, carbonyl iron powder, as a soft magnetic material, has the advantages of wide use frequency band, stable performance, especially high permeability and low magnetic loss at high frequency. It is widely used in radio communication, navigation, radar and other equipment, and is expected to play the advantages of high frequency and low consumption in photovoltaic and energy storage converter and voltage transformation scenarios with high-frequency power semiconductors; in terms of national defense and military industry, carbonyl iron powder is used as the core basic material and stealth Aircraft and ships are closely related. ” “In addition, in terms of food additives, high-purity carbonyl iron powder is considered to be an ideal food iron supplement and an ideal raw material for the production of iron supplement. Carbonyl iron powder has great application potential and needs to be continuously explored by the industry,” Li shangkui said
Previously, the carbonyl iron powder industry was dominated by BASF of Germany for a long time. Before 2015, the market share of the company in the Chinese market remained above 80% for a long time, and the medium and high-end market (such as carbonyl iron-based soft magnetic powder for inductance) was above 95%. Now this phenomenon has been fundamentally reversed. With a number of performance and technical indicators superior to foreign competitive products, Jiangxi Yuean Advanced Materials Co.Ltd(688786) several years ago, it began to break the monopoly of world giants in the field of medium and high-end carbonyl iron powder, and realized the large-scale production of carbonyl iron powder in China. At present, the main manufacturers of carbonyl iron powder in China include Jiangxi Yuean Advanced Materials Co.Ltd(688786) , Jiangsu Tianyi, Shaanxi Xinghua Chemistry Co.Ltd(002109) , Jilin Zhuo innovative materials Co., Ltd., Jiangyou Hebao nano materials Co., Ltd. and Jinchuan Group Co., Ltd.
“The company’s carbonyl iron powder T6 series products, similar products of foreign multinational companies can only maintain D50 at about 1.5 microns, while the company can now achieve 1.2 microns. The advantage of low powder fineness is that it can reduce the power consumption of ultra-fine inductors.” Wang Bing, general manager of the company, told reporters: “The lower the fineness, the higher the selling price. The 1.2 micron level is now selling for more than 200000 yuan a ton. There is a multinational company. It used to use the products of BASF in Germany. Now the company has become their largest supplier, limited by the production capacity. At present, the company only supplies about 5 tons a month, but their demand is 15 tons. After the company’s fund-raising project is completed, it is expected to catch up with and surpass the world giants in the field of carbonyl iron powder. ”
“In the future, with the continuous innovation of technology and the continuous improvement of production process and the gradual improvement of product performance, the production cost of carbonyl iron powder in the industry will gradually decline, which will greatly enrich the application scope of products, provide more space for the selection of high-performance materials for downstream applications, and is expected to explore emerging application scenarios in the fields of national defense, military industry, new energy and other fields and create incremental market demand.” Li shangkui, chairman of the company, told reporters.
high performance metal powder material market
expected to maintain high growth
In recent years, Jiangxi Yuean Advanced Materials Co.Ltd(688786) is also actively distributing the field of atomized alloy and actively extending to the downstream deep processing fields such as soft magnetic powder based on carbonyl iron and atomized alloy. The data show that atomized alloy powder has excellent corrosion resistance. After being formed by metal injection molding and other processes, it is widely used in aerospace, consumer electronics, 5g base station and terminal and other scenes. According to Wang Bing, general manager of Jiangxi Yuean Advanced Materials Co.Ltd(688786) company, with the further development of 5g intelligent terminal equipment and automotive electronics industry, the market of corresponding high-performance structural and functional metal powder materials is expected to maintain high growth, including atomized alloy powder.
Different from the carbonyl iron segment market, the atomized alloy market is a market with lower entry threshold and low industry concentration. In the early years, more than 100 large and small enterprises were doing it in the low-end market. Sandvikosprey in the UK and atmix in Japan have also occupied the medium and high-end market in the Chinese market for a long time. Since 2015, Jiangxi Yuean Advanced Materials Co.Ltd(688786) ‘s products have gradually partially replaced similar imported products from Germany, Russia, Japan, the United States and other countries, and now the substitution rate is gradually increasing.
Jiangxi Yuean Advanced Materials Co.Ltd(688786) chairman Li shangkui believes that to break through, we should rely on technical advantages on the one hand and cost advantages on the other. The amorphous powder material developed by the company based on the atomization process is carrying out small batch mass production. After the material is made into inductive devices, the loss is lower than that of traditional materials in the high-frequency working environment, which will effectively reduce the circuit power consumption and is expected to become a new business growth point of the company in the future.
As a new material, many applications of atomized alloy need to be explored, but it is certain that 3D printing will be an important application field of atomized alloy powder in the future. “Different from the requirements of traditional powder metallurgy for metal powder, 3D printing puts forward higher requirements for the particle size and particle size distribution, sphericity, oxygen content and other characteristics of metal powder, and atomization method is the main technology for industrialized production of spherical powder at present. Therefore, the development of high-performance and low-cost powder preparation technology and the development of special metal powder for 3D printing are the focus of future research on atomization powder preparation technology.” Jiangxi Yuean Advanced Materials Co.Ltd(688786) general manager Wang Bing said.
However, there is an inevitable process of exploration for the industrialization of research results. The same is true for carbon nanotubes with high market heat, Wang Bing said, “At present, the industry has not really brought the advantages of carbon nanotubes into full play. Although the research of carbon nanotubes is very cutting-edge, it is a little different from that developed by enterprises. The research uses a single layer and the production is multi-layer. Therefore, the performance optimization of carbon nanotubes that can be produced remains to be clarified. However, it is certain that carbon nanotubes must be a very good product direction in the future. The company originally planned to use carbonyl Based iron and carbon nanotubes are combined to make some microwave absorbing materials. After learning that carbon nanotubes have great application prospects in conductivity and energy storage, they are also doing relevant research and development and application research in this regard. “
