High-Conductivity Copper Alloys, Technical Specifications, and Global Industrial Applications
Explore our premium grade, high-conductivity custom copper products optimized for demanding industrial systems.
Electrolytic Tough Pitch (ETP) Copper, designated globally as UNS C11000, serves as the industrial benchmark for projects demanding exceptional electrical and thermal conductivity. With a copper purity rating typically exceeding 99.90%, C11000 exhibits an Electrical Conductivity rating of 100% to 101.5% IACS (International Annealed Copper Standard). This outstanding performance is made possible by controlling key trace impurities during the electrolytic refining process, optimizing the transfer rate of electrons through its crystalline structure.
In addition to electrical efficiency, C11000 contains a controlled oxygen content, generally between 0.02% and 0.04% (in the form of cuprous oxide). This oxygen content acts as an internal cleanser during smelting, oxidizing other elements and trapping them as inert oxides. However, this structure makes C11000 susceptible to hydrogen embrittlement when exposed to reducing atmospheres above 370°C (700°F). For high-temperature brazing or welding applications, engineers typically specify Oxygen-Free High Conductivity (OFHC) variants or Tellurium Copper (C14500) to maintain structural integrity.
"For modern engineering projects, selecting the right copper grade involves balancing physical performance, machining capability, and long-term environmental resistance. Our OEM manufacturing options ensure your exact specification requirements are met."
The metallurgical attributes of C11000 make it highly malleable and ductile, suited for cold forming, bending, drawing, and heading. When selecting C11000 for your production lines, it is essential to specify the temper designation according to your component requirements:
