The copper round bar (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 offers excellent cold and hot formability and is ideal for soft soldering, but not recommended for hard soldering in reducing atmospheres or for machining.
For copper rods, please contact Evek GmbH. As a trusted supplier, we ensure fast and reliable global delivery.
Thanks to its high electrical and thermal conductivity, copper round bar is 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 systems (elements for heating/cooling);
- Construction (decorative interior cladding, facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings, chokes, and coils.
Main properties of copper round rod:
- Excellent cold and hot forming abilities;
- Superior processing properties;
- Outstanding soft solderability;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in reducing atmosphere;
- Low machinability.
