The copper round bar, designated as Cu-ETP, is made from electrolytically refined, oxygenated copper. It contains at least 99.9% copper and a maximum of 0.04% oxygen. Due to possible hydrogen embrittlement, this material is not suitable for welding. It offers excellent formability both hot and cold and is very well suited for soft soldering. However, brazing in a reducing atmosphere and machining are not recommended.

Thanks to its outstanding electrical and thermal conductivity, round copper rod is widely used in heating systems (radiators, heat exchangers), electrical machinery (motors, coils), and components such as terminals and contact holders.
Common applications for copper rod include:
- Heating and cooling systems (heating/cooling elements);
- Construction (decorative interior cladding and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and coils/chokes.
Key properties of copper round rod:
- Excellent cold and hot workability;
- Great processing characteristics;
- Outstanding soft solderability;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in reducing environments;
- Poor machinability.
