On May 9, 2022, the Hay Think team came to the production workshop of TGJT Stainless Steel Technology Corporation, and saw that the rolling mill production line was rolling ultra-thin stainless steel foil products with a thickness of 0.02 mm and a width of 640 mm.
"We are currently the only company in the world that can mass-produce wide-width soft stainless steel precision foil products, from materials to products, all independently developed. At first, China's key technologies in this area were controlled by others, and now many developed countries need our products! ” Dr. Duan, the CTO of the R&D center who is keeping an eye on the products on the production line, proudly introduced to the Hay Think team.
As a wide and ultra-thin precision stainless steel strip, ultra-thin stainless steel foil is used in aerospace, high-end electronics, new energy fields, and folding screen mobile phones.
At present, the thickness of the company's ultra-thin stainless steel foil is 0.015 mm, and the actual width is more than 640 mm. "This is also the widest and thinnest stainless steel precision foil in the world."
Material innovation leads to industrial changes. TGJT recently released two high-end new materials in the world:
One is a professional expansion alloy for the mask plate, which breaks the Japanese monopoly and fills the market gap of similar products in China;
The other is a high-end new material of special corrosion-resistant alloy for lithography, which solves the problem of the "bottleneck" process of chip manufacturing.
In 2022, the company's R&D team is developing and producing a new type of composite material that generates instant heat in combination with the special properties of precision stainless steel foils and the needs of usage scenarios, to rapidly de-ice aircraft wings. Putting on this "jacket" successfully can not only greatly reduce the energy consumption of the aircraft, but also greatly reduce the safety hazards caused by the lift-off and hanging on the ice. At present, the new high-end aviation lightweight composite materials for deicing have achieved phase Technological breakthrough.
Breakthroughs have been achieved in the process technology and series product development of high-performance alloy products, and the research and improvement of corrosion resistance of high-quality stainless steel precision strip products.
The R&D team has worked closely with innovative R&D platforms such as Huawei's "2012 Lab", Huaxin Optoelectronics, and BOE, and achieved gratifying results in important products in the 5G communication field and high-end electronics field such as flexible display substrates and masks. Cooperating with Shanghai Jiaotong University, Tongji University, Taiyuan University of Technology, Taiyuan University of Science and Technology, etc., it undertakes 2 national science and technology projects and leads one provincial science and technology project.
"ultra-thin precision stainless steel foil' has formed more than 20 varieties of products in 3 categories. There are currently two directions of innovation, one is special alloy foils used in aerospace, high-end electronics, new energy and other fields, the other is It is used for special properties such as coating films and aircraft deicing devices.
