This copper round bar is made from Cu-ETP, an electrolytically refined copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to its composition, it is not suitable for welding (risk of hydrogen embrittlement) or brazing in a reducing atmosphere. However, it offers excellent cold and hot workability and is ideal for soft soldering. Machining and hard soldering are not recommended.
To purchase copper rods, contact Evek GmbH. As a trusted supplier, we ensure smooth and reliable worldwide shipping.
Thanks to its high electrical and thermal conductivity, copper round bar is commonly used in heating and cooling systems (such as radiators and heat exchangers), electrical machinery (motors, coils, chokes), and various electrical components (terminals, contact holders).
Typical applications for copper rods include:
- Heating and cooling technology (elements for heating/cooling);
- Construction (decorative accents for interiors and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings, chokes, and coils.
Key features of round copper rod:
- Excellent formability in both cold and hot conditions;
