China's high-precision metal material industry

The secret to the success of China's high-precision metal material industry in the past 10 years is rooted in the triple synergy of technological breakthroughs, specialized and innovative cultivation, and policy empowerment. Represented by Taiyuan Iron and Steel Group, we have achieved global mass production of 0.015mm 'hand torn steel', breaking through the three world-class challenges of rolling shape control, surface purity and flexibility control of ultra-thin stainless steel. We have obtained 46 patents and support high-end manufacturing such as folding screens and lithography machines. Tongchuang Purun, Guizhou Dingcheng Rongxin and other 'specialized, refined and innovative' enterprises focus on segmented tracks. The former breaks through the preparation of 5N grade ultra-high purity copper and tantalum target materials, providing key interconnect materials for 3-nanometer chips; The latter conquered the core components of hydraulic piston pumps with a precision of 0.001 millimeters, breaking the monopoly of Germany and Japan, and increasing the qualification rate to 99.8%. Pangang successfully rolled 0.1mm wide titanium foil, filling the gap in hydrogen fuel cell electrode plate materials. Under the strong guidance of 'Made in China 2025' and the 'Specialized, Refined, Unique, and New' policy system, materials are being promoted to shift from 'pricing by ton' to 'value by gram'. The domestication rate of downstream new energy composite current collectors and semiconductor target materials is rapidly increasing, forming an independent closed loop of 'materials equipment application'. The industry is moving from 'following' to 'leading', reshaping the global high-end metal materials landscape.
