Description
🧹 Extended Overview
C10200 Copper Plate is a top-tier, high-purity, oxygen-free copper sheet that delivers unmatched electrical and thermal performance. With a minimum copper content of 99.95% and oxygen levels below 0.001%, it offers superior conductivity, formability, and corrosion resistance. Designed for critical applications where even trace oxygen contamination can lead to degradation, C10200 Copper Plate is trusted in the aerospace, electronics, medical, and scientific industries.
Produced in compliance with ASTM B152 and often cross-referenced with AMS 4500/4501, this material is known for its exceptional cleanliness, purity, and consistency. Unlike common ETP copper (C11000), C10200 Copper Plate eliminates the risk of hydrogen embrittlement, making it the preferred choice for high-vacuum and reducing-atmosphere environments.
Additionally, C10200 exhibits excellent malleability and compatibility with precision etching, vacuum brazing, and electron beam welding, making it well-suited for semiconductor fabrication tools and ion-beam instrumentation. Its low magnetic permeability and exceptional purity also contribute to its use in sensitive magnetic shielding components and particle physics research.
🔍 Detailed Chemical Composition
| Element | Symbol | Typical Value (%) |
|---|---|---|
| Copper | Cu (incl. Ag) | ≥ 99.95 |
| Oxygen | O | ≤ 0.001 |
This ultra-low oxygen content ensures minimal oxidation, gas release, and improved structural reliability in critical applications. Compared with deoxidized or tough pitch copper, C10200’s oxygen-free status eliminates spattering and porosity in high-vacuum applications.
🔧 Mechanical & Physical Properties
| Property | Value Range | Condition |
| Tensile Strength | 220–280 MPa | Annealed |
| Yield Strength | 70–200 MPa | Depends on temper |
| Elongation | 30–45% | High ductility |
| Hardness (Vickers) | 40–60 HV | Soft to 1/2 Hard |
| Density | 8.94 g/cm³ | Standard |
| Electrical Conductivity | ≥ 101% IACS | Outstanding |
| Thermal Conductivity | ≈391 W/m·K | Exceptional |
The combination of ductility and conductivity makes C10200 Copper Plate an excellent material for precision machining, press forming, and vacuum-grade welding. The uniform grain structure contributes to predictable deformation behavior and low springback during deep drawing or cold forming.

For most demanding industrial and clean-environment applications, C10200 Copper Plate offers the optimal balance of performance and affordability.
C10200 is often preferred over C10100 because the difference in performance is minimal, while C10200 is significantly more economical. In contrast, C11000 is widely used in general electrical applications but is not suitable for high-vacuum or hydrogen-rich atmospheres.
