Oxygen-free copper rod is a high-purity copper rod with extremely low oxygen content, typically less than 10 parts per million (ppm). This high purity results in superior electrical and thermal conductivity compared to standard copper. Oxygen-free copper is used in applications where these properties are critical, such as in electrical and electronic components, superconducting wires, and scientific instruments.
