The copper round bar 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, this material is unsuitable for welding. It offers excellent cold and hot formability, making it ideal for soft soldering. However, hard soldering in a reducing atmosphere and machining are not recommended.
To purchase copper rods, please contact Evek GmbH. We are a reliable supplier and ensure smooth worldwide deliveries.
Thanks to its outstanding electrical and thermal conductivity, copper round bar is commonly used in heating systems (radiators, heat exchangers), electrical equipment (motors, coils), and components like terminals and contact carriers.
Typical applications 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 bar:
- Excellent cold and hot formability;
- Good processing characteristics;
- Very suitable for soft soldering;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
