Our copper round bar (Cu-ETP) is made from electrolytically refined, oxygen-containing copper, with a copper content of at least 99.9% and a maximum oxygen content of 0.04%. Due to possible hydrogen embrittlement, this material is not suitable for welding. It offers excellent cold and hot formability and is ideal for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
To order a copper rod, contact Evek GmbH. We are a reliable supplier and offer smooth worldwide delivery.
With its outstanding electrical and thermal conductivity, copper round bar is commonly used in heating technology (radiators, heat exchangers), electrical machines (motors, chokes/coils), and various components (terminals, contact carriers).
Typical applications of copper rod include:
- Heating and cooling technology (elements for heating/cooling);
- Construction (decorative purposes for interiors and facades);
- Electrical engineering and device manufacturing;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings, chokes, and coils.
Key properties of copper round rod:
- Excellent cold and hot forming capability;
- Outstanding processing characteristics;
- Excellent suitability for soft soldering;
- Good corrosion resistance;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
