Products Description
C10100, commonly known as Oxygen-Free Copper (OF Copper), is a pure copper material characterized by its extremely low oxygen content (typically no more than 0.0005%) and high purity (copper content not less than 99.99%). It represents one of the highest grades of industrial pure copper.
Chemical Composition
The core of C10100 lies in its extremely high purity and strict control over impurities, particularly oxygen.
| Element | Content (%) | Notes |
|---|---|---|
| Cu | ≥ 99.99 | Principal Element |
| O | ≤ 0.0005 | Key Control Index |
| P | ≤ 0.0003 | - |
| Total Other Impurities | ≤ 0.001 | Includes Silver (Ag), etc. |
Physical Properties
C10100 possesses excellent electrical and thermal conductivity, which are its most important physical properties.
| Property | Value / Description |
|---|---|
| Density | 8.94 g/cm³ |
| Melting Point | 1083 °C |
| Electrical Conductivity (20°C) | ≥ 101% IACS |
| Thermal Conductivity | ~ 391 W/(m·K) |
| Coefficient of Thermal Expansion | 17.0 × 10⁻⁶ /K (20-300°C) |




Mechanical Properties
Mechanical properties depend on the material's condition (e.g., annealed or hard).
| Condition | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| Annealed (O) | 220 - 270 | ~ 70 | ≥ 45 |
| Hard (H) | 350 - 400 | ~ 330 | ≥ 4 |
