Tellurium Copper
Overview
C14500 is a free-machining copper with a small addition of tellurium that dramatically improves machinability to 85% — the highest of any copper. It maintains 93% IACS electrical conductivity, making it ideal for machined electrical components.
As a C14500 tellurium coppersupplier, Triton Bronze & Metals stocks copper in round bar, hex bar, flat bar — all cut to length and shipped from US mills. Certified mill test reports available to meet your quality requirements.
