What is a C11000 copper pipe?
C11000 (UNS C11000, ASTM B152/B187, ISO CW004A)
Also known as phosphorized copper or ETP copper (Electrolytic Tough Pitch), with a minimum copper content of 99.90% and trace oxygen (≤0.06%).
Product Features
Exceptional electrical conductivity (~100% IACS), ideal for electrical applications.
High thermal conductivity (394 W/m·K), suitable for heat exchangers and cooling systems.
Excellent ductility and formability, enabling cold working and complex shaping.
Good corrosion resistance in atmospheric and aqueous environments.
Susceptible to "hydrogen embrittlement" in high-temperature (>370°C) reducing atmospheres.
