C11000 Copper Plate Properties & Specifications
Our copper plates are tested to guarantee compliance with the required C11000 material properties. Below are the detailed specifications for Cu-ETP / T2 copper.
C11000 Chemical Composition
The performance of an etp copper plate relies on its purity. C11000 contains a minimum of 99.90% Copper (Cu) and a controlled oxygen content.
| 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 and thermal parameters make it the ideal material for heat dissipation and power distribution.
| 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 Sheet & Plate Mechanical Properties
The temper dictates the formability and rigidity of the plate. C11000 h02 offers a balance of strength and bending capability, while H04 provides maximum structural rigidity.
| Temper (Hardness) | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (Rockwell F) | Typical Application |
| O60 (Soft Annealed) | 220 - 260 | ~ 69 | ≥ 30% | 40 - 45 | Deep Drawing, Roofing |
| H02 (Half Hard) | 250 - 320 | ~ 200 | 12% - 20% | 75 - 82 | Stamped Parts, Busbars |
| H04 (Hard Drawn) | 310 - 380 | ≥ 280 | 4% - 8% | 85 - 90 | Rigid Machined Plates |

Processing & Value-Added Services
As a comprehensive c11000 copper sheet manufacturer, we don't just supply raw plates. We provide extensive in-house metal processing to deliver semi-finished or finished parts directly to your assembly line:
Precision Cutting: Laser cutting, waterjet cutting, and CNC shearing for exact dimensions with zero heat-affected zones on thick plates.
C11000 Copper CNC Machining: Milling, drilling, and routing for thick heatsink C11000 copper plates and custom electrical switchgear components.
Surface Treatment: Delivery of polished T2 copper sheets (mirror or brushed finish) for architectural and decorative applications. Tin-plating is available for electrical contacts.
Factory
Producing high-quality copper plates requires immense pressure and precision control. Our facility is equipped to ensure superior flatness and exact thickness across the entire plate surface.
Plate & Sheet Production Equipment
Reversing Cold Rolling Mills: Equipped with automatic gauge control (AGC) to ensure strict thickness tolerances (down to ±0.01mm) for thin copper sheets and foils.
Hot Rolling Lines: Designed for processing thick T2 copper plates (up to 100mm+) with uniform internal grain structure.
Tension Leveling & Flattening Machines: Crucial for eliminating internal residual stress, ensuring the copper plate remains perfectly flat during your subsequent CNC machining processes.
Testing & Inspection Laboratory
Every batch undergoes rigorous quality assurance before packing:
Optical Emission Spectrometers (OES): Verifying the 99.90% minimum copper purity.
X-Ray Thickness Gauges: Inline continuous monitoring of sheet thickness during the rolling process.
Surface Roughness Testers & Hardness Testers: Guaranteeing the required finish and mechanical temper.
FAQ
What is C11000 grade copper?
C11000 is the UNS (Unified Numbering System) designation for Electrolytic Tough Pitch (ETP) copper. It is an unalloyed, commercially pure copper known for its exceptional electrical and thermal conductivity, making it the standard material for power transmission and thermal management.
What is the difference between C11000 and 110 copper?
There is no difference. "110 copper" or "Alloy 110" are simply common, abbreviated industry terms for the official ASTM/UNS designation, which is C11000.
What is the purity of C11000 copper?
C11000 has a minimum guaranteed purity of 99.90% Copper (Cu). It also contains a very small, controlled amount of oxygen (typically 0.02% to 0.04%), which is characteristic of "Tough Pitch" copper.
Is C11000 pure copper?
In commercial and industrial terms, yes. With a purity of 99.90%, it is considered commercially pure. However, it is not 100% absolute pure copper, nor is it "Oxygen-Free" (like C10200), as the trace amount of oxygen is deliberately retained to improve its casting and processing characteristics.
Is C110 copper bendable?
Yes, but its bendability depends entirely on its temper. Soft annealed (O60) C11000 is highly ductile and easily bent, formed, or deep-drawn. C11000 H02 (Half Hard) can be bent to a certain radius without cracking, often used for stamped busbars. However, H04 (Hard) has high yield strength and is difficult to bend cold; it is meant for rigid, flat applications.
What is the price of C11000 copper?
The C11000 copper price is calculated based on two main factors: the daily LME (London Metal Exchange) base copper commodity rate, plus the factory fabrication cost. Fabrication costs vary depending on the thickness, dimensions, and whether you need custom cutting or CNC machining. Please contact us for today's specific price.
