Arc Copper Welding Wire: A Modern Industrial Essential

Arc copper welding wire has emerged as a critical material in heavy industries due to its superior conductivity (98% IACS) and tensile strength (350-450 MPa). The global market grew by 6.2% CAGR from 2020 to 2023, with Chinese suppliers now controlling 43% of global production capacity. This wire type reduces arc instability by 22% compared to aluminum alternatives, making it indispensable for precision welding.

Technical Advantages and Performance Metrics

High-purity copper alloys (≥99.97%) enable exceptional thermal transfer (385 W/m·K) while maintaining low oxidation rates (0.15% at 500°C). Key technical specifications include:

Melting point range: 1,080-1,100°C
Spatter reduction: 35% vs. standard wires
Diameter tolerance: ±0.01mm
