C11000 Copper Tube Properties & Specifications
Our seamless C11000 copper pipes are manufactured to strictly meet international standard parameters. Below are the detailed technical specifications for the t2 copper material / Cu-ETP.
C11000 Chemical Composition
The high purity of C11000 is the foundation of its performance. It inherently contains a controlled amount of oxygen.
| Element | Symbol | Percentage (%) |
| Copper (Including Silver) | Cu + Ag | ≥ 99.90% Min |
| Oxygen | O | 0.02% - 0.04% Max |
| Bismuth | Bi | ≤ 0.001% Max |
| Lead | Pb | ≤ 0.005% Max |
| Total Impurities | - | ≤ 0.03% Max |
C11000 Copper Physical Properties
The physical characteristics of C11000 material make it the ultimate choice for thermal management and electrical current delivery.
| Property | Metric Value | Imperial Value |
| Density | 8.89 - 8.94 g/cm³ | 0.321 - 0.323 lb/in³ |
| Melting Point | 1083°C | 1981°F |
| Electrical Conductivity (Annealed) | 100% - 101% IACS | 100% - 101% IACS |
| Thermal Conductivity (at 20°C) | 388 - 394 W/m·K | 226 Btu/ft²·h·°F |
| Modulus of Elasticity (Tension) | 115 GPa | 17,000 ksi |
C11000 Tube Mechanical Properties (By Temper)
The mechanical performance depends entirely on its temper (hardness). Below is a general guide comparing soft annealed tubes vs. hard drawn tubes (such as C11000 H04).
| Temper (Hardness) | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (Rockwell F) | Typical Application |
| O60 (Soft Annealed) | 220 - 260 | ~ 69 | ≥ 40% | 40 - 45 | HVAC, Coils, Tight Bending |
| H02 (Half Hard) | 250 - 320 | ~ 200 | 14% - 25% | 75 - 82 | Formed Connectors, Pluming |
| H04 (Hard Drawn) | 310 - 380 | ≥ 280 | 6% - 10% | 85 - 90 | Rigid Bus Pipes, Structural |

Processing & Value-Added Services
Buying raw materials is only the first step. To save you fabrication time and reduce scrap rates, our facility is equipped to provide comprehensive processing services for all c11000 copper pipe orders:
Custom Cut to Length: Precision sawing of C11000 copper pipes to your exact required dimensions.
C11000 Copper CNC Machining: Drilling, tapping, flattening, and end-forming for tubular components.
Surface Treatment: Polished t2 copper tubes and tin-plating services for enhanced corrosion resistance in switchgear environments.
Factory Capabilities & Quality Control
Production Equipment
Our production lines are engineered specifically for high-precision non-ferrous metal drawing and extrusion:
High-Tonnage Extrusion Presses: Ensuring dense, seamless microstructures for all copper billets before drawing.
Precision Cold Drawing Benches: Achieving exact Outside Diameter (OD) and Wall Thickness (WT) tolerances (up to ±0.03mm) for straight tubes and coils.
Vacuum Bell-Type Annealing Furnaces: Essential for producing soft annealed (O60) and half-hard (H02) t2 copper tubes. The vacuum environment prevents surface oxidation, ensuring a bright, clean finish without scaling.
Testing & Inspection Laboratory
Quality is verified, not guessed. We conduct 100% inline and offline testing before shipment. Our in-house QC lab is equipped with:
Optical Emission Spectrometer (OES): To strictly verify the C11000 chemical composition (ensuring Cu ≥ 99.90% and controlling oxygen/impurity levels).
Eddy Current Flaw Detectors: 100% non-destructive testing (NDT) on all seamless tubes to detect hidden internal cracks, voids, or leaks.
Universal Tensile Testing Machines: To verify yield strength, tensile strength, and elongation according to ASTM standards.
Rockwell & Vickers Hardness Testers: Ensuring the material temper (H02, H04) matches your exact requirements for bending or machining.
Export Standard Packaging & Shipping
Copper is a relatively soft metal and is highly susceptible to surface oxidation when exposed to moisture during sea freight. We utilize heavy-duty, seaworthy packaging to ensure your C11000 copper pipes arrive in pristine condition, ready for immediate use.
Surface Protection: All copper tubes are tightly wrapped in VCI (Volatile Corrosion Inhibitor) film or vacuum-sealed plastic bags with desiccants to completely isolate them from saltwater humidity and prevent greening/tarnishing.
End Caps: Plastic protective caps are fitted to both ends of the tubes to prevent deformation of the chamfers and keep the inner bore free from dust and debris.
Outer Packing: Packed securely in ISPM-15 compliant, fumigation-free wooden cases or strongly reinforced wooden pallets.
Internal Buffering: Corrugated paper, bubble wrap, and wooden separators are used inside the crates to prevent scratching and collision during transit.
FAQ
What is C11000 copper?
C11000 is an Electrolytic Tough Pitch (ETP) copper. It is the most widely used grade of copper worldwide, characterized by a minimum copper purity of 99.90% and outstanding electrical and thermal conductivity.
Is C11000 copper the same as C110?
Yes. "C110" is simply the common, shortened industry name for the official UNS designation "C11000". They refer to the exact same ETP copper material.
What is the chemical composition of C11000 alloy?
The C11000 chemical composition is highly pure. It contains a minimum of 99.90% Copper (Cu) and a small, controlled amount of Oxygen (O), typically between 0.02% and 0.04%.
Is C11000 copper oxygen-free?
No, C11000 is not oxygen-free. Because it is "Tough Pitch" copper, it inherently contains a small amount of oxygen. If your application involves high-temperature heating in a hydrogen environment (like extensive brazing or welding), oxygen-free copper grades like C10100 or C10200 are recommended to prevent hydrogen embrittlement.
What is the difference between C11000 and C12200?
The main difference lies in their application and composition. C11000 (ETP) has high electrical conductivity and is designed for electrical/electronic applications. C12200 (DHP) is phosphorus-deoxidized copper; it has lower electrical conductivity but excellent welding and brazing properties, making it the standard choice for plumbing, water tubes, and HVAC systems.
What is the price of copper C11000?
The C11000 copper price is not a fixed number. It is calculated based on the daily fluctuating LME (London Metal Exchange) base copper price, plus the fabrication cost (which depends on whether you need standard pipes, specific tempers, or custom cut sizes). Please contact our sales team with your exact specifications for an accurate, up-to-date quote.
