C-276 Hastelloy is a high-performance corrosion-resistant nickel-based alloy, renowned for its outstanding corrosion resistance and mechanical properties. It is widely used as a substrate material for the fabrication of HTS tapes.

REBCO superconducting target materials（REBa₂Cu₃O_7-x), are mainly composed of lanthanide or yttrium series elements. Large-sized and high-purity superconducting target are the key raw materials for depositing superconducting layers.
