[China has developed a new "skeleton" for high-temperature superconducting strips] September 2nd, high-temperature superconducting strips have a cheaper and stronger "skeleton". The reporter learned from the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences on the 2nd that after more than three years of research, the institute's scientific research team successfully developed a new "skeleton" of high-temperature superconducting strips - an iron-based alloy base strip, code-named "DW01". Verified by Shanghai Superconducting Technology Co., Ltd., the key performance indicators of superconducting strips prepared using this base strip are significantly better than traditional Hastelloy base strip products. This marks an important step for China to achieve independent control of the core materials of high-temperature superconducting strips. (Science and Technology Daily)
