REBCO tapes are currently being produced by various companies, each employing unique combinations of materials and deposition processes. To effectively design and optimize their use in power devices, it is crucial to ascertain their critical field characteristics and understand their flux pinning properties. In this work, we conducted a comprehensive investigation involving electrical transport and magnetization measurements on coated conductors (CCs) produced by Shanghai Superconductor Technology Co., Ltd. (SST). Our findings reveal that the flux pinning energy of these CCs exhibits a collective pinning behavior across the entire range of magnetic fields under consideration. Moreover, the behavior of these CCs in high magnetic fields suggests that their design is well-suited for low-temperature, high-power applications.
