C11000 Electrolytic Tough Pitch Copper Rod – High Conductivity for Electrical and Industrial Applications

The C11000 Electrolytic Tough Pitch (ETP) Copper Rod is one of the most widely used and highly valued copper materials in the electrical and industrial sectors. Known for its excellent electrical conductivity, superior thermal performance, and robust mechanical characteristics, C11000 copper offers reliable functionality across a range of demanding environments. This product description provides a complete overview of its properties, specifications, production processes, applications, and customization options—designed to offer engineers, procurement teams, and manufacturers a clear reference for selecting the right copper rod solution.

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.

2. Key Features & Benefits

• High Electrical Conductivity (≥101% IACS)
  Ensures efficient current flow with reduced power loss.

• Excellent Thermal Conductivity
  Ideal for heat exchangers, cooling components, and energy systems.

• High Purity Copper (≥99.90%)
