Low Oxygen Content for Better Drawing Performance
Our oxygen free copper wire rod has one key advantage over standard rods. The oxygen content is extremely low. Oxygen creates problems during wire drawing. It causes porosity. It also leads to breakage. Our rod minimizes these issues. The low oxygen content also improves conductivity. Copper with less oxygen conducts electricity more efficiently. This matters in high-performance cable applications. Our customers report good yield rates with our rod. They experience fewer breaks during drawing. This reduces downtime and waste. The rod also performs well in high-temperature processing. It resists hydrogen embrittlement. This is important for certain welding and brazing operations.
Production Quality Controls
We perform regular surface checks during production. Our team looks for bubbles and cracks. These defects become breaks when drawn into wire. We reject any rod that shows surface issues. Our workers have developed a trained eye for spotting imperfections. They inspect every coil before it leaves the factory. We also check the oxygen content periodically. This confirms we stay within specification. The rod comes in 16mm and 20mm diameters. Both sizes are readily available from stock. The material meets GB/T5585.1-2026 standards.
Technical Specifications
Copper purity reaches Cu≥99.90%. Total impurities remain below 0.10%. Conductivity is ≥97.3% IACS. Resistivity at 20°C stays ≤0.0177 Ω·mm²/m. Density is 8.9 g/cm³. Tensile strength ranges 220–260 MPa. Yield strength exceeds 170 MPa. Hardness measures 65–90 HV. Elongation is 17% or above. We stock 16mm and 20mm diameters.
Main Use in Premium Cable Manufacturing
Oxygen free copper wire rod serves as a primary material for cable production. Premium wire and cable manufacturers specify it. The high quality justifies the cost. It produces better finished wire with fewer defects. Copper wire processing also uses this rod. Many copper products start with this material. We have supplied cable manufacturers for years. Export sales now form a significant part of our business. Before production, we confirm your specifications. During production, we can provide progress updates. Packaging protects the rod during shipping.
