- **Caution**: 

### Q: What are the main applications for this high-purity copper rod?
**A**: This copper rod is specifically designed for electrical wire and cable manufacturing, including power transmission cables, building wiring, automotive wiring, and telecommunications cables where high conductivity and reliability are essential.

### Q: What is the difference between electrolytic copper and oxygen-free copper rods?
**A**: Electrolytic copper rods offer high purity (typically 99.9%+) with excellent conductivity, while oxygen-free copper rods have oxygen content below 10ppm, providing enhanced ductility and resistance to hydrogen embrittlement for demanding electrical applications.

### Q: How does surface roughness affect copper rod performance in electrical applications?
**A**: Controlled surface roughness (typically Ra &lt; 0.8μm) ensures smooth wire drawing, reduces friction during processing, minimizes surface defects, and maintains consistent electrical properties throughout the manufacturing process.
