Core Insights - The research team at the Institute of Metal Research, Chinese Academy of Sciences, has successfully achieved industrial-scale production of high-purity ton-level Hastelloy alloy using self-developed purification technology, which is crucial for the production of second-generation high-temperature superconducting tapes [1][2] - The second-generation high-temperature superconducting tapes are essential for creating powerful magnetic fields necessary for controlled nuclear fusion, and the production of these tapes has previously relied on imported Hastelloy alloys, which are expensive and have uncertain supply timelines [1] - The newly developed Hastelloy alloy has purity levels that meet or exceed those of imported materials, and the team has also overcome key technical challenges in processing, resulting in ultra-thin metal strips with specific dimensions and excellent thermal stability and mechanical properties [1] Production and Collaboration - The metal strips produced by the Institute of Metal Research have undergone validation with relevant enterprises, successfully completing the large-scale production of nearly one kilometer of high-temperature superconducting tape [2] - A framework cooperation agreement has been established between the Institute of Metal Research and related enterprises for the supply of 20 tons of metal strips, with plans for further collaboration to optimize the production process [2]
