What is a C11000 copper pipe?

GNEE supplies C11000 Electrolytic Tough Copper (ETP) bars or solid copper strips. We offer a variety of sizes and can cut to length to your specifications.

C11000 Electrolytic Tough Copper (ETP) is produced directly from carefully selected refined cathodes and castings under strictly controlled conditions to prevent contamination of the pure oxygen-free metal during processing. This OFHC copper production method ensures ultra-high purity, with a copper content of up to 99.99%. Due to the extremely low impurity content, the inherent properties of elemental copper are fully expressed.

This is the most commonly used copper, suitable for a wide range of electrical applications. The minimum conductivity rating for ETP is 100% IACS, with a purity requirement of 99.9%. Its oxygen content is typically 0.02% to 0.04%. Most ETP currently on the market meets or exceeds the 101% IACS specification. Similar to OF copper, for purity purposes, the silver (Ag) content is included in the copper (Cu) content.
