The copper round bar, marked as Cu-ETP, is made from electrolytically refined, oxygenated copper with a minimum purity of 99.9% and an oxygen content up to 0.04%. This high-purity copper is not suitable for welding because of hydrogen embrittlement, but it offers excellent cold and hot forming properties and is ideal for soft soldering. It is not recommended for brazing in a reducing atmosphere or for machining.

Due to its outstanding electrical and thermal conductivity, round copper rods are widely used in heating technology (radiators, heat exchangers), electrical machines (motors, coils), and various components (terminals, contact carriers).
Common applications for copper rod include:
- Heating and cooling systems (elements for heating and cooling);
- Construction (decorative interior cladding and facades);
- Electrical engineering and device construction;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Windings and chokes/coils.
Key properties of copper round rod:
- Outstanding cold and hot workability;
- Excellent processing characteristics;
- Very good for soft soldering;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
