SuNAM

SuNAM makes second-generation high-temperature superconducting wire, a material that carries electricity with virtually no resistance, enabling far more efficient power transmission and stronger magnets than conventional copper-based systems.

Building on that core wire, it also supplies superconducting magnets, cables, and related manufacturing equipment to customers in power-grid, medical imaging, nuclear-fusion research, and defense applications. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company covers the full superconducting technology chain, from raw wire through finished magnet systems.
