What is a C11000 copper pipe?

Copper alloy C1100 electrolytic tough pitch is a very pure alloy of copper (99.90% min. Cu).

Cu-ETP C1100 also referred to as the UNS C11000/EN CW004A copper alloy.

It has excellent forming properties. It is a versatile alloy because of its resistance to corrosion, high electrical and thermal conductivity, and its aesthetic quality.

Cu-ETP C1100 is widely used in transformers, power cables, electrical parts, laboratory research and development.
