The diversity and the applications of copper conductors are numerous.
From a single wire to a complex cable, from the lowest section to the highest, copper is available, annealed, hard, bare or plated.
A lot of applications use the properties of copper :
- Energy
- Telecommunication
- Welding…
The copper qualities generally used for the production of conductors are :
- ETP copper, or Cu-a1, with oxygen content between 200 and 300 ppm.
- OF copper, oxygen-free or Cu-c1, with very small content in oxygen (20 ppm max.) able to resist to hydrogen brittleness during a heating.
