The copper round bar, Cu-ETP grade, is electrolytically refined, oxygenated copper with a minimum purity of 99.9% and a maximum oxygen content of 0.04%. Due to hydrogen embrittlement, this material is not suitable for welding. It offers excellent cold and hot workability and is ideal for soft soldering. However, brazing in a reducing atmosphere and machining are not recommended.
For copper rod purchases, contact Evek GmbH. As a trusted supplier, we ensure fast and reliable worldwide delivery.
Thanks to its outstanding electrical and thermal conductivity, the copper round bar is used in heating technology (radiators, heat exchangers), electrical machinery (motors, inductors/coils), and various components (terminals, contacts).
Common applications for copper rod include:
- Heating and cooling systems (elements, exchangers)
- Construction (decorative interior and façade cladding)
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings and inductors/coils
Key properties of the copper round bar:
- Excellent formability (cold and hot)
- Very good processing properties
- Outstanding for soft soldering
- Good resistance to corrosion
- Not suitable for welding
- Not recommended for brazing in reducing conditions
- Poor machinability
