- TC Materials Co., Ltd. is a South Korea-based industrial materials manufacturer specializing in the development, processing, and fabrication of advanced copper conductors, winding wires, and electrical conductive components for power grid infrastructure, heavy electric machinery, and electric vehicle applications. The company's core product portfolio encompasses continuously transposed conductors (CTC) for extra-high-voltage and high-voltage power transformers and power generation equipment; oxygen-free high-conductivity (OFHC) copper billets, copper rods, and copper alloy bars; paper-insulated, film-insulated, and varnish-coated rectangular copper magnet wires for industrial transformers and high-voltage power transmission systems; enameled copper wires and precision fine rectangular wires engineered for electric vehicle (EV) traction drive motors and electronic equipment; copper busbars and conductive terminal connectors for automotive battery modules, power distribution units, and energy storage systems (ESS); and high-voltage stator assembly coils, custom motor coils, and comprehensive stator overhaul and rewinding services for heavy industrial electric motors and power plant turbines. TC Materials supplies its products to leading heavy electrical equipment manufacturers, cable producers, transformer fabricators, and automotive component suppliers, including HD Hyundai Electric, Hyosung Heavy Industries, LS Cable & System, and Taihan Cable & Solution, serving domestic South Korean markets as well as export destinations across Asia, North America, and Europe. Founded in 1989 and headquartered in Ulsan, South Korea, the company operates production and processing facilities across Ulsan and Busan, functioning as a subsidiary member of the BioSmart Group. In recent developments, the company finalized a corporate reorganization and expanded its manufacturing capacity to address the surge in global grid modernization and artificial intelligence data center power transmission demand, culminating in its public listing on the KOSDAQ market (KRX: 125020) in May 2025 via a merger with Daishin Balance No. 15 Special Purpose Acquisition Company. Furthermore, TC Materials has expanded its technical partnerships with domestic and international electrical machinery manufacturers to accelerate commercial delivery of next-generation low-loss continuously transposed conductors for ultra-high-voltage power networks and expanded its specialized winding wire lines for high-voltage electric mobility powertrains.
