Electrolytic Tough Pitch Copper
Material No. Unified Numbering System (UNS): C11000
Chemical Composition
| Element | Cu(1,2) | Oxygen |
|---|---|---|
| Min (%) | 99.90 Min. | 0.04 Max. |
- Cu value includes Ag.
Cu-ETP has a very high electrical and thermal conductivity. It has excellent forming properties. Due to its oxygen content soldering and welding properties are limited.
Common Fabrication Processes
- Forging
- Extruding
- Drawing
- Ring Rolling
- Bending
- Machining
