Description
Premium C11000 Copper Foil – High Conductivity & Malleability for Industrial Use
🔹 Overview
C11000 Copper Foil is a high-purity, oxygen-free, electrolytic tough pitch (ETP) copper foil known for its excellent electrical and thermal conductivity, outstanding malleability, and superior corrosion resistance. It is widely used in electronic, industrial, and architectural applications that demand highly conductive, formable, and reliable copper material.
Composed of a minimum of 99.90% pure copper, C11000 conforms to ASTM B152 standards and is designated as UNS C11000. It offers exceptional surface quality, tight thickness tolerance, and excellent solderability, making it the ideal choice for use in PCB manufacturing, transformers, battery tabs, EMI/RFI shielding, and metal crafts.
C11000 copper also possesses excellent fatigue resistance, a key feature for flexible circuits and components subject to frequent thermal or mechanical stress. Its low magnetic permeability and high recyclability make it a sustainable and functional material for a wide range of environmentally conscious engineering designs.
🧪 Chemical Composition (Typical)
| Element | Content (wt%) |
|---|---|
| Copper (Cu) | ≥ 99.90% |
| Oxygen (O) | ≤ 0.04% |
The extremely low oxygen content ensures minimal risk of hydrogen embrittlement during high-temperature operations and enhances compatibility with vacuum or inert environments.
⚙️ Mechanical & Physical Properties
| Property | Typical Value |
| Tensile Strength | 220–385 MPa |
| Yield Strength | 65–200 MPa |
| Elongation | ≥ 30% |
| Hardness | 40–85 HV (depending on temper) |
| Density | 8.89 g/cm³ |
| Electrical Conductivity | ≥ 100% IACS |
| Thermal Conductivity | ~390 W/m·K |
| Melting Point | 1083°C |
These properties make C11000 Copper Foil ideal for both cold working and brazing operations, allowing for precise stamping, laminating, and forming processes. Its high ductility and excellent bonding ability to adhesives and resins also support its use in flexible printed circuit boards and shielding tapes.
