Products Description
C10100 is a high-purity oxygen-free copper (OFE or OFC), belonging to the copper category under the American Society for Materials Research (ASTM). Its core characteristics include a copper content ≥99.99%, oxygen content strictly controlled to ≤0.001% (10 ppm), and limited impurities such as sulfur, lead, and zinc (all ≤0.001%). This ultra-low impurity level makes it significantly superior to ordinary pure copper (such as C11000) in conductivity, ductility, and corrosion resistance, making it a high-end copper material in industrial applications.
Core Physical and Chemical Properties
Electrical and Thermal Properties
Conductivity: Up to 101% IACS (International Standard for Annealed Copper), the highest grade among copper materials, with a conductivity of 58.6 MS/m.
Thermal Conductivity: Up to 391 W/(m·K), suitable for high-efficiency heat dissipation applications.
Low Resistance Loss: Almost no signal attenuation when transmitting high-frequency current, making it an ideal material for communication and power transmission.
Mechanical Properties
Density: 8.94 g/cm³, close to the theoretical density of pure copper (8.96 g/cm³).
Ductility and Strength: Tensile strength approximately 210 MPa, elongation ≥45%, combining flexibility and toughness; cold working deformation rate can reach over 80%.
Hardness: 85.2 HV (Vickers hardness), which can be improved through cold working hardening.
Corrosion Resistance and Stability
No risk of hydrogen embrittlement: Extremely low oxygen content avoids hydrogen embrittlement (hydrogen permeation leading to embrittlement) in high-temperature reducing environments.
Chemical Corrosion Resistance: Stable in dry environments and weak acid/alkali media, suitable for chemical pipelines and marine equipment.

FAQ
Q: What ASTM standards cover C10100 products?
A: Key ASTM standards include:
ASTM B170: Oxygen-Free Electrolytic Copper-Refinery Shapes
ASTM F68: Oxygen-Free Copper in Unalloyed Forms for Electron Devices
ASTM B152: Sheet, Plate, Strip, and Rolled Bar
ASTM B187: Bus Bar, Rod, and Shapes
Q: What are the common tempers or hardness levels available for C10100?
A: C10100 is available in various tempers, including:
Annealed (O60 / Soft): For maximum ductility.
Hard Drawn (H04): For higher strength.
As-Fabricated: Varies based on the manufacturing process.
Q: Can C10100 be welded and brazed?
A: Yes, it has excellent weldability and brazeability. Common methods include TIG welding, electron beam welding, and furnace brazing in a protective atmosphere to prevent oxidation.
Q: How does the cost of C10100 compare to C11000 (ETP Copper)?
A: C10100 is significantly more expensive than C11000 due to the complex manufacturing process required to achieve its ultra-high purity and oxygen-free state.
