Special-shaped copper rod

Special-shaped copper rod

This copper busbar (custom extruded profile) is manufactured from high-purity electrolytic copper (Cu ≥ 99.95%), featuring a precision-machined interlocking structure for stable assembly. It combines exceptional electrical conductivity, mechanical rigidity, and corrosion resistance, suitable for high-load industrial applications.

Core Performance

Electrical & Thermal Properties:
◦ Electrical conductivity: ≥98% IACS (at 20°C)
◦ Thermal conductivity: ≥390 W/(m·K)
• Mechanical Strength:
◦ Tensile strength: ≥220 MPa (annealed state) / ≥350 MPa (hardened state)
◦ Elongation: ≥30% (annealed) / ≥5% (hardened)
• Durability:
◦ Excellent corrosion resistance (oxidation-resistant surface; compatible with anti-tarnish treatments)
◦ High thermal stability (maintains performance at -40°C to 120°C)
