Abstract
Since 2014, Sam Dong Co., Ltd. has successfully developed high-performance MgB2 superconducting wires with a kilometer-scale. Herein, we studied performances of various MgB2 wires fabricated by the Sam Dong with different Cu fractions and diameters for practical applications. Critical current densities of our commercial wire, 18+'1'Cu multifilamentary MgB2 wire, are estimated to be 270,000 A/㎠ at 3 T and 4.2 K and 100,000 A/㎠ at 2 T and 20 K, respectively. We further discuss research progress of various MgB2 superconducting wires at Sam Dong Co., Ltd and make an effort to align with customers' requirements.
