The copper round bar designated Cu-ETP is an electrolytically refined, oxygenated copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to possible hydrogen embrittlement, it is not suitable for welding. The material is easy to form both cold and hot, and is ideal for soft soldering. However, hard soldering in a reducing atmosphere and machining are not recommended.
To purchase copper rods, please contact Evek GmbH. As a trusted supplier, we ensure smooth and reliable worldwide deliveries.
Thanks to its excellent electrical and thermal conductivity, copper round rod is commonly used in heating systems (radiators, heat exchangers), electrical machinery (motors, coils), and components such as terminals and contact carriers.
Applications for copper rod include:
- Heating and cooling technology (elements for heating and cooling);
- Construction (decorative interior cladding and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings, chokes, and coils.
Key properties of copper round rod:
- Excellent cold and hot formability;
- Very good processing qualities;
- Excellent suitability for soft soldering;
- Good corrosion resistance;
- Not suitable for welding;
- Not recommended for brazing in reducing atmospheres;
- Poor machinability.
