This copper round bar, designated as Cu-ETP, is an electrolytically refined and oxygen-containing copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to its composition, the material is not suitable for welding because of the risk of hydrogen embrittlement. It offers excellent cold and hot forming properties, and is ideal for soft soldering. However, it is not recommended for brazing in a reducing atmosphere or for machining.

Thanks to its outstanding electrical and thermal conductivity, round copper rod is commonly used in heating technology (such as radiators and heat exchangers), electrical machines (like electric motors and chokes/coils), and various components (including terminals and contact carriers).
Applications for copper rod include:
- Heating and cooling systems (elements for heating and cooling);
- Construction (decorative interior cladding and façades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical installations;
- Wire windings, chokes, and coils.
Key properties of round copper rod:
- Excellent hot and cold formability;
- Very good processing characteristics;
- Superb soft solderability;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in reducing atmospheres;
- Poor machinability.
