This copper round bar, designated as Cu-ETP, is made from electrolytically refined and oxygen-containing copper. It contains at least 99.9% copper and a maximum of 0.04% oxygen. Due to its oxygen content, it is not suitable for welding, as hydrogen embrittlement may occur. It offers excellent formability both hot and cold, and is perfect for soft soldering. However, it is not recommended for brazing in a reducing atmosphere or for machining.
To purchase copper rods, contact Evek GmbH. We are a trusted supplier offering fast and straightforward worldwide shipping.
Thanks to its high electrical and thermal conductivity, copper round bar is commonly used in heating technology (such as radiators and heat exchangers), electrical equipment (motors, chokes/coils), and electronic components (terminals, contacts).
Typical applications for copper rod include:
- Heating and cooling technologies (heaters, coolers);
- Construction (decorative interior and facade cladding);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and coils.
Key properties of round copper rod:
- Excellent cold and hot workability;
