C11000 Copper Strip & Sheet (ETP Copper / T2 / Cu-ETP)
C11000 is electrolytic tough pitch (ETP) copper — a ≥99.90% Cu grade that combines very high electrical & thermal conductivity (≈97% IACS, 388 W/m·K) with good corrosion resistance, formability and excellent brazing/soldering performance. It is the workhorse copper for power transmission, busbars and electronic parts.
Key Features & Advantages
-
High conductivity ≈97% IACS and thermal conductivity 388 W/(m·K).
