Premium C11000 Copper Round Bar – ASTM B187 Standard, Solid Copper Alloy 110 Rod, Stock Ready
Product Overview
Our Premium C11000 Copper Round Bar is a high-conductivity, oxygen-containing electrolytic tough pitch (ETP) copper product manufactured to meet the stringent requirements of ASTM B187 and other global standards. With a minimum copper purity of 99.90%, this solid round bar offers exceptional electrical and thermal conductivity, excellent formability, and reliable performance in demanding industrial, electrical, and mechanical applications.
Ideal for manufacturers seeking consistent quality and immediate availability, our C11000 copper rods are stock-ready in a wide range of diameters and lengths—ensuring fast turnaround and reduced lead times without compromising on material integrity.
Chemical Composition (ASTM B187 / UNS C11000)
The chemical composition of C11000 copper is tightly controlled to ensure optimal performance:
| Element | Content (%) | Maximum Limit |
|---|---|---|
| Copper (Cu) + Silver (Ag) | ≥ 99.90% | — |
| Oxygen (O) | 0.02–0.04% | 0.04% |
| Lead (Pb) | — | 0.005% |
| Iron (Fe) | — | 0.005% |
| Sulfur (S) | — | 0.005% |
| Phosphorus (P) | — | 0.002% |
| Other Impurities (each) | — | 0.001% |
| Total Impurities | — | 0.10% |
⚠️ Note: Oxygen content enhances conductivity but limits use in reducing atmospheres or high-temperature hydrogen environments (risk of hydrogen embrittlement).
Mechanical Properties (As-Hot-Rolled Condition)
| Property | Typical Value |
|---|---|
| Tensile Strength | 210–260 MPa |
| Yield Strength (0.2%) | 60–120 MPa |
| Elongation | 40–50% (in 50 mm) |
| Hardness (HV) | 40–60 |
| Electrical Conductivity | ≥100% IACS (at 20°C) |
| Thermal Conductivity | ~398 W/(m·K) |
| Density | 8.94 g/cm³ |
| Melting Point | 1083°C |
Values may vary slightly based on diameter, processing method (hot-rolled vs. annealed), and temper.
