The copper round bar, designated 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 the risk of hydrogen embrittlement, it is not suitable for welding. The material offers excellent cold and hot formability 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, copper round rod is used in heating technology (radiators, heat exchangers), electrical machines (motors, chokes/coils), and various components (terminals, contact carriers).
Common applications include:
- Heating and cooling systems (elements, exchangers)
- Construction (decorative elements for interiors and facades)
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings and chokes/coils
Main features of copper round rod:
- Excellent cold and hot forming capabilities
- Easy to process
- Great for soft soldering
- Good resistance to corrosion
- Not suitable for welding
- Cannot be brazed in a reducing atmosphere
- Poor machinability
