The copper round bar marked as Cu-ETP is made from electrolytically refined, oxygenated copper with a minimum purity of 99.9% copper and a maximum oxygen content of 0.04%. Due to possible hydrogen embrittlement, this material is not suitable for welding. It has excellent cold and hot forming properties and is ideal for soft soldering. However, hard soldering in a reducing atmosphere and machining are not recommended.

Thanks to its outstanding electrical and thermal conductivity, this copper round bar is commonly used in heating technology (radiators, heat exchangers), electrical equipment (motors, chokes/coils), and various components (contacts, terminals).
Main applications for copper rod include:
- Heating and cooling systems (elements for heating/cooling);
- Construction (decorative purposes for interiors and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings, chokes, and coils.
Key properties of the copper round rod:
- Excellent cold and hot formability;
- Very good processing characteristics;
- Easy to soft solder;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
