Global leading company in amorphous alloy materials
QDYL Amorphous Alloy Technology Coporation is an invisible champion enterprise in the field of amorphous alloys in China, and a high-tech enterprise dedicated to the R&D production and sales of advanced magnetic metal materials.
The company has formed three major materials and product series of amorphous alloys, nanocrystalline alloys, and magnetic powders, including amorphous alloy ribbons and iron cores, nanocrystalline ultra-thin ribbons, atomized and crushed powders, and magnetic powder cores, which are mainly used in The power distribution field also extends to downstream industries such as new infrastructure, rail transit, consumer electronics, new energy vehicles, home appliances, and particle accelerators.
The company has established long-term and stable cooperative relations with well-known domestic and foreign power industry manufacturers, and has become a strategic partner of China Aero Engine Group,CRRC[Jointly developed crystal soft magnetic materials with CRRC for use in maglev trains],Huawei, Tesla, BYD,China's State Grid,Toshiba,ABB and other companies. Its products are sold in North America, Europe, Japan and other parts of the world.
At the same time, its new products, nanocrystalline ultra-thin ribbons and magnetic powders and products have been expanding well in consumer electronics, electric vehicles and other fields.
QDYL is one of the few companies in China's magnetic materials industry that has both material composition design and evaluation capabilities, extreme process equipment realization capabilities, and product application development capabilities. The current amorphous alloy ribbon technology achievements have been appraised by the China Electrical Equipment Industry Association to achieve "international advanced The technical achievements of nanocrystalline ultra-thin ribbons have been appraised by the Chinese Society of Metals to reach the “international leading” level.
"Wide and ultra-thin iron-based nanocrystalline strip" project won the special prize of China Metallurgical Science and Technology Award in 2021
Through joint technical research, QDYL has developed continuous production equipment and manufacturing processes for ultra-thin nanocrystalline ribbons, filling the gaps in wide-width ultra-thin nanocrystalline ribbons and continuous manufacturing technology. The nanocrystalline ultra-thin ribbon produced by the company has a width of up to 142mm, which can meet the performance and size requirements of high-power mid- and high-frequency magnetic devices; the thickness of the nanocrystalline ultra-thin ribbon reaches 14-18 μm, which has a high technical threshold and barriers. Since mass production in 2019, it has focused on market expansion in emerging industries and gradually replaced the market space of traditional magnetic materials such as ferrite.
Applications of the Wide and ultra-thin iron-based nanocrystalline strip
Wide and ultra-thin iron-based nanocrystalline strips have the performance advantages of low loss, high magnetic permeability, wide and ultra-thin, and are highly recognized by the high-end market. They are widely used as key strategic materials in the new generation of information technology, smart grid, rail transit, and new energy. Automobiles and other fields will support hundreds of billions of industrial clusters; due to the manufacturing cost advantage of continuous production, magnetic component products are also widely used in home appliances (microwave ovens, air conditioners, refrigerators, washing machines, LED TVs, air purifiers, dishwashing) Traditional industries such as machines, ovens, water heaters, etc.), various power sources (UPS, PC computers, servers, medical, etc.), welding machines and photovoltaic inverters have achieved good economic and social benefits. In addition to the above applications, it can also be applied to medium and large-capacity power electronic high-frequency transformers to support the solution of large-scale grid integration of wind and solar energy and other renewable energy in the smart grid.
The company has 256 patents, including 196 invention patents and 60 utility model patents. At the same time, it also undertook scientific research projects such as the National Development and Reform Commission, the Ministry of Industry and Information Technology's central investment key industry revitalization and technological transformation projects, the National Torch Plan project, the China Aviation Development Innovation Fund project, and the AVIC Technology Innovation Fund project.
The company has broken through the mass production technology of 14 nanometer crystal strips, and has the capacity to produce samples with thicknesses of 12-14 nanometers. At the same time, it is developing samples of nanocrystalline super thin strips of 10-12 nanometers, which will help solve the problem of my country’s key materials. The technical "stuck neck" problem. This kind of ultra-thin nanocrystals can create the necessary magnetic field environment for ion acceleration energy in the field of particle accelerators. The export of nanocrystal products with ultra-high technical requirements of 14 nanometers and below is restricted by foreign countries.
