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.
