What is a C11000 copper pipe?
C11000 Electrolytic Tough Pitch Copper (ETP Copper) is the most widely used grade of copper worldwide. With a minimum copper content of 99.90% and excellent electrical and thermal conductivity, it is an essential material for electrical, electronic, and industrial applications. C11000 combines outstanding ductility, workability, and corrosion resistance, making it suitable for both forging and fabrication processes.

Manufacturing & Fabrication of C11000 Copper
C11000 has excellent fabrication and forming properties, making it widely used in forging, extrusion, rolling, and machining.
Cold Forming: Excellent
Hot Forming: Excellent
Welding: Suitable (resistance welding, gas-shielded arc welding)
Soldering / Brazing: Excellent
Machinability: Limited due to high ductility
⚠ Note: Hydrogen embrittlement should be avoided during heating in reducing atmospheres.
