Electrolytic Tough Pitch Copper (ETP)
Overview
C11000 is the most widely used copper in the world — the standard for electrical conductivity. With 101% IACS conductivity, it is the baseline material for bus bars, electrical connectors, and power distribution systems.
As a C11000 electrolytic tough pitch copper (etp)supplier, Triton Bronze & Metals stocks copper in round bar, flat bar, sheet, and more — all cut to length and shipped from US mills. Certified mill test reports available to meet your quality requirements.
