Engineered to meet the exact specifications of South Korea’s rigorous electrical and motor manufacturing standards, our core product lineup excels in weight reduction and thermal efficiency.
The Seoul Metropolitan Area, including Incheon and Gyeonggi-do, represents a powerhouse of high-tech manufacturing. As South Korea accelerates its transformation toward electric vehicles (EVs), robotics, and eco-friendly smart infrastructures, local manufacturers are shifting from traditional heavy-copper materials to high-performance Enameled Round Aluminum Wire.
This shift is driven by crucial economic and engineering imperatives. Aluminum provides a 60% reduction in weight compared to copper, optimizing inertial values in high-speed electric powertrains. Crucially, enameled aluminum wire serves as a cost-stabilizing asset against volatile copper market pricing, allowing industrial enterprises in Seoul's industrial parks (such as the Gasan Digital Complex and Seongnam High-Tech Valley) to remain globally competitive.
Global supply chains demand components that meet international compliance benchmarks. Our production processes align with IEC, NEMA, and JIS standards, satisfying the requirements of South Korea's major players like Hyundai, Kia, Samsung, and LG. From high-frequency transformers to HVAC compressor motors, we guarantee consistent quality, precise dimensional tolerance, and superior windability.

Enameled round aluminum wire provides a 60% weight reduction compared to copper, improving dynamic efficiency in moving components. It also helps manage raw material costs amid volatile copper pricing, offering stable supply costs for long-term manufacturing programs.
Yes, our enameled wires are engineered to comply with the KS C 3006 standard, as well as equivalent JIS C 3216, NEMA MW 1000, and IEC 60317 specifications, ensuring easy integration into South Korean manufacturing lines.
EC grade aluminum has approximately 61% the conductivity of IACS copper. To match the current carrying capacity of copper, the cross-sectional area of the aluminum wire must be increased by about 1.6 times. This is typically managed by resizing the motor core slots.
We recommend ultrasonic welding, crimping with specialized piercing terminals, or using specialized flux for soldering aluminum. These methods prevent aluminum oxide formation and ensure reliable, low-resistance connections.
Standard manufacturing leads are 15 to 25 days depending on quantities and sizes. Ocean transit from Shanghai to Incheon takes 2-3 days, ensuring short delivery windows for Gyeonggi-do electronics hubs.
Explore our complete range of high-efficiency magnet wires, transposed conductors (CTC), and paper-covered profiles designed for heavy-duty transformers and electric drivetrains.
