Product Overview

What are Copper C11000 (ETP) Threaded Rods?

Copper C11000 (ETP) threaded rods are high-conductivity copper fasteners manufactured from electrolytic tough pitch copper, conforming to ASTM B187 and UNS C11000. These rods are cold-drawn or rolled to produce continuous threads along their length, making them ideal for electrical, thermal, and architectural fastening applications where maximum conductivity and corrosion resistance are required.

With a minimum copper content of 99.90% and electrical conductivity of at least 101% IACS, Copper C11000 threaded rods are the industry standard for busbar connections, earthing systems, and high-frequency grounding in substations, switchgear, and power distribution assemblies.

Material Chemistry

Copper C11000 (ETP) Chemical Composition

Copper C11000 (ETP) Threaded Rods are produced from either tin-stabilized Naval Brass C46400 or aluminium-nickel-iron Aluminium Bronze C63000, with elemental limits per ASTM and MIL-B-24059. Tin (0.5–1%) in Naval Brass prevents dezincification in seawater; aluminium and nickel additions in Al Bronze C63000 provide non-sparking ATEX Zone 1 compliance.

Chemical Composition per ASTM B187

ElementComposition (%)
Copper (Cu)99.90% min
Silver (Ag)0.002% min
Oxygen (O)0.04% max
Other Elements (total)0.05% max
? All heats verified by NABL-accredited spectrometry. Electrical conductivity tested per ASTM B193.

Why Copper C11000 (ETP) Alloy Composition Matters for Threaded Rods

99.90% Cu — Maximum Conductivity
The high copper content ensures electrical conductivity of at least 101% IACS, making these rods ideal for grounding, busbar, and power distribution connections where minimal resistance is critical.
Low Oxygen Content
Oxygen content below 0.04% prevents embrittlement and ensures excellent ductility and workability, allowing easy threading and forming without cracking.
Trace Silver
The presence of trace silver further enhances conductivity and thermal performance, supporting use in high-frequency and high-temperature electrical assemblies.
