The copper round bar with the designation Cu-ETP is a 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 not suitable for welding. It is, however, highly formable both hot and cold, and is ideal for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
For purchasing copper rods, please contact Evek GmbH. We are a reliable supplier and ensure smooth worldwide shipments.
With its high electrical and thermal conductivity, copper round bar is commonly used in heating technology (radiators, heat exchangers), electrical machinery (motors, coils), and various electrical components (terminals, connectors).
Typical applications include:
- Heating and cooling systems (elements, exchangers);
- Construction (decorative elements, cladding, facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Windings for coils and chokes.
Main properties of copper round bar:
- Excellent cold and hot formability;
- Superior workability;
- Outstanding soft solderability;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
