Copper Conductors

Copper conductors are among the most widely used materials in the industry today. ETO offers a diverse range of copper conductors classified by their purity: pure copper, oxygen-free copper (OFC), and single crystal copper (OCC). Single crystal copper, with its exceptional purity exceeding 99.9999%, is ideal for applications that demand precise and efficient signal transmission. To meet varying requirements, we offer custom surface treatments, including cladding and coating.

FAQs About Copper Conductors

Copper purity is the most critical factor. Higher copper content results in better conductivity. For example, oxygen-free copper (with a purity above 99.95%) achieves conductivity close to that of theoretical pure copper. Additionally, operating temperature affects conductivity, as higher temperatures reduce efficiency.

The current-carrying capacity is a key indicator. Conductivity testing instruments can measure its electrical performance precisely. Additionally, high-quality conductors have smooth, polished surfaces and well-rounded strands, reflecting superior manufacturing.

Copper conductors are primarily used for power transmission, making them essential in the cable industry. They are also widely used in electronics, electrical equipment, and communication systems for internal signal transmission.

Single crystal copper has fewer impurities and lower resistance, reducing energy loss by 8%-13% compared to standard copper. Its enhanced ductility and strength improve durability and simplify processing.

Oxygen-free copper (OFC) is the optimal choice. With a copper content exceeding 99.95%, it ensures low resistance and high current transmission efficiency, making it ideal for wire and cable materials.

Repeated cold processing can distort the crystalline lattice of copper, increasing internal stress and resistance. Annealing restores the lattice structure, reducing internal stress and enhancing overall conductivity.

Oxygen-free copper wire (OFC) is recommended for generator coils. Its low resistance minimizes heat-related energy loss and maintains consistent magnetic field strength for reliable performance.
