C110 Copper Round Rod - 99.95% Purity 12mm-80mm For Welding Electrodes
C110 Copper Round Rods are crafted from 99.95% pure electrolytic copper, offering unmatched conductivity and weldability for high-performance welding electrodes, electrical contacts, and resistance welding applications. Compliant with ASTM B187, EN 13602, and JIS H3250 standards, these rods are precision-drawn to diameters of 12mm–80mm with ultra-low oxygen content (≤0.03%), ensuring clean, spatter-free welds in industrial and automotive manufacturing.
Key Advantages:
- Ultra-High Purity: 99.95% Cu with minimal impurities (O ≤0.03%, Pb ≤0.005%) for consistent arc stability.
- Superior Conductivity: 100% IACS (58 MS/m) for efficient energy transfer in welding systems.
- Precision Machining: Tight diameter tolerances (±0.05mm) for seamless electrode fabrication.
- Corrosion Resistance: Resists oxidation and carbon buildup in high-temperature welding environments.
- Global Compliance: Certified to RoHS, REACH, and AWS D18.1 welding standards.
- Custom Solutions: Cut-to-length (300mm–6m), polished, or tin-plated surfaces.
