The copper round bar, classified as Cu-ETP, is made from electrolytically refined, oxygenated copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to its composition, this material is not suitable for welding because of the risk of hydrogen embrittlement. However, it offers excellent cold and hot forming properties, is ideal for soft soldering, and has good corrosion resistance. Hard soldering in a reducing atmosphere and machining are not recommended.

Thanks to its high electrical and thermal conductivity, copper round rod is commonly used in heating technology (such as radiators and heat exchangers), electrical machinery (motors, chokes, coils), and various components (terminals, contact carriers).
Typical uses for copper rod include:
- Heating and cooling technology (elements for heating/cooling);
- Construction (decorative use for interiors and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and chokes/coils.
Main characteristics of round copper rod:
- Excellent hot and cold formability;
- Very good processing qualities;
- Great for soft soldering;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
