Oxygen-free Copper Rod
Oxygen-free copper rod refers to a copper rod with extremely low oxygen content (typically ≤0.003%), prepared from high-purity electrolytic copper through processes such as vacuum smelting or inert gas protection smelting. It has the following features:
High Electrical Conductivity: Purity ≥99.97%, conductivity ≥100% IACS, suitable for scenarios requiring excellent conductivity.
Superior Workability: Good ductility, can be processed into thin wires, cables, etc., with strong weldability and corrosion resistance.
Low Oxygen Content: Almost free of oxides, avoiding performance degradation caused by oxidation during high-temperature processing of ordinary copper rods.

PRODUCT PARAMETERS
Application Fields
Power Industry: Manufacturing ultra-high voltage cables, transformer winding wires, transmission conductors, etc.Electronics and Electricals: Producing precision electronic components, integrated circuit leads, high-frequency cables, etc.

Special Materials: Used for high-reliability conductive components in aerospace and military industries, as well as raw materials for high-purity alloys.

Production Process
The mainstream process is: electrolytic copper raw material → vacuum smelting (or inert gas protection) → continuous casting and rolling → surface treatment (anti-oxidation) → finished product.
