Ultrafine carbonyl iron [email protected] micron grade
JXYA is committed to the R&D and production of high-end micro-nano metal powders. In the field of powder metallurgy with the widest range of applications, carbonyl iron powder can not only improve the yield and strength of products, but also prolong the life of products, so it is considered to be the most One of the good additives.
"In terms of electronic power, carbonyl iron powder, as a soft magnetic material, has the advantages of wide operating frequency band, stable performance, especially high magnetic permeability and low magnetic loss at high frequency, and is widely used in radio communication, navigation, radar and other equipment. It is expected to play the advantages of high frequency and low consumption in conjunction with high-frequency power semiconductors in the conversion and voltage conversion scenarios of photovoltaic and energy storage;
In terms of national defense and military industry, carbonyl iron powder as the core basic material is closely related to stealth aircraft and ships.
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 supplements. The application potential of carbonyl iron powder is very large, which still needs to be continuously explored by the industry. "
Previously, the carbonyl iron powder industry was dominated by Germany's BASF for a long time. Before 2015, the market share of BASF in the Chinese market remained above 80% for a long time, and the mid-to-high-end market (such as carbonyl iron-based soft magnetic powder for inductors) was above 95%.
Now this phenomenon has been fundamentally reversed. With many performance and technical indicators superior to foreign competitors, JXYA began to break the monopoly of world giants in the field of medium and high-end carbonyl iron powder a few years ago, and realized carbonyl iron powder in China. of large-scale production. At present, the main manufacturers of carbonyl iron powder in China are JXYA, JSTY, SXXH Chemical, JLZC New Material Technology, JYHB Nanomaterials Co., Ltd. and JC Group Co., Ltd., etc.
JXYA's carbonyl iron powder T6 series products, similar products of foreign multinational companies can only maintain D50 at about 1.5 microns, while JXYA can now achieve 1.2 microns, and the advantage of low powder fineness is that it can reduce the power consumption of ultra-micro inductors.
"The lower the fineness, the higher the price. The 1.2-micron grade is now sold for more than 200,000 yuan per ton. There are many Fortune 500 multinational companies. They used to use BASF products in Germany, and now JXYA products. It has gradually replaced BASF's products and has become their number one supplier.
High Performance Metal Powder Materials Market
In recent years, JXYA is also actively deploying the field of atomized alloys, and actively extending to downstream deep processing fields such as soft magnetic powders based on carbonyl iron and atomized alloys.
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 stations and terminals. With the further development of 5G smart terminal equipment and the automotive electronics industry, the corresponding high-performance structural and functional metal powder materials market is expected to maintain high growth, including atomized alloy powders.
Different from the carbonyl iron market segment, the atomized alloy market is a market with lower entry barriers and low industry concentration. In the early years, there were more than 100 large and small companies in the low-end market, such as Sandvik Osprey in the United Kingdom and Atmix in Japan. For a long time, it has also occupied the mid-to-high-end market in the Chinese market in gas atomized alloy powder and water atomized alloy powder.
Since 2015, JXYA's products have gradually partially replaced similar imported products from Germany, Russia, Japan, the United States and other countries, and now the replacement rate is gradually increasing.
To achieve a breakthrough, we must rely on technological advantages on the one hand, and cost advantages on the other hand. The amorphous powder material developed by JXYA based on the atomization process is being produced in small batches. After the material is made into an inductive device, the loss is lower than that of traditional materials in a high-frequency working environment, which will effectively reduce circuit power consumption and is expected to become The company's new business growth point in the future.
As a new material, many applications of atomized alloys remain to be explored, but it is certain that 3D printing will be an important application field of atomized alloy powders in the future. "Different from traditional powder metallurgy's requirements for metal powders, 3D printing puts forward higher requirements for metal powder particle size and particle size distribution, sphericity, oxygen content and other characteristics, and atomization is currently the main technology for industrial production of spherical powders. Therefore, the development of high-performance and low-cost powder preparation technology and the development of special metal powders for 3D printing are the focus of future research on atomization powder technology.
