The copper round bar with material designation Cu-ETP is made from electrolytically refined, oxygen-containing copper. It contains at least 99.9% copper and a maximum of 0.04% oxygen, making it unsuitable for welding due to the risk of hydrogen embrittlement. The material offers excellent cold and hot forming properties and is ideal for soft soldering. However, brazing in a reducing atmosphere and machining are not recommended.
To purchase a copper rod, contact Evek GmbH. We are a reliable supplier and offer fast, worldwide delivery.
Thanks to its high electrical and thermal conductivity, copper round bars are widely used in heating technology (radiators, heat exchangers), electrical machinery (motors, chokes/coils), and various components (terminals, contact carriers).
Common applications for copper rod include:
- Heating and cooling systems (elements for heating and cooling);
- Construction (decorative use in interior cladding and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and chokes/coils.
