Oxygen-Free Copper (OFC) wire rod is manufactured with less than 10 ppm of oxygen and over 99.99% copper purity, ensuring exceptional electrical performance.

Through precise deoxidation, it offers superior electrical and thermal conductivity, smooth surface quality, and excellent workability and reliability. It is widely used in solar ribbon wires, high-end audio cables, semiconductor and EV power lines, and communication systems requiring high conductivity and purity.
