1. Product Overview

C11000 ETP copper is a high-purity copper grade made through an electrolytic refining process. As an industrial standard for conductive materials, it contains 99.9% minimum pure copper with a controlled oxygen content. With a conductivity rating of ≥101% IACS, this material is ideal for electrical transmission and energy systems requiring minimal electrical resistance.

The C11000 ETP Copper Rod is available in a variety of diameters and custom-cut lengths, making it suitable for machining, forming, and fabrication. Its excellent ductility, weldability (excluding hydrogen environments), and corrosion resistance further enhance its versatility across power, electronics, engineering, and heat transfer industries.
