The Cu-ETP copper round bar is made from electrolytically refined, oxygenated copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to its composition, this material is not suitable for welding because of possible hydrogen embrittlement. However, it offers excellent formability (both cold and hot) and is ideal for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
To purchase copper rod, please contact Evek GmbH. We are a reliable supplier and offer straightforward worldwide shipping.
Thanks to its excellent electrical and thermal conductivity, copper round rod is widely used in heating technology (radiators, heat exchangers), electrical equipment (motors, coils), and various components (terminals, contact carriers).
Typical applications for copper rod include:
- Heating and cooling systems
- Construction and decorative interior/exterior cladding
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings, chokes, and coils
Key properties of copper round rod:
- Outstanding cold and hot formability
- Excellent processing characteristics
- Superior soft solderability
- Good resistance to corrosion
- Not suitable for welding
- Cannot be brazed in a reducing atmosphere
- Poor machinability
