The copper round bar (Cu-ETP) is made from electrolytically refined, oxygen-containing copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to possible hydrogen embrittlement, this material is not suitable for welding. However, it offers excellent cold and hot formability and is ideal for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
To purchase a copper rod, please contact Evek GmbH. As a reliable supplier, we ensure fast and straightforward worldwide delivery.
Thanks to its high electrical and thermal conductivity, copper round bar is commonly used in heating technology (radiators, heat exchangers), electrical machines (electric motors, coils), and various components (terminals, contact holders).
Typical applications of copper rod include:
- Heating and cooling systems (heating and cooling elements)
- Construction (decorative elements for interiors and facades)
- Electrical and equipment engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings and coils
Key properties of copper round rod:
- Excellent cold and hot formability
- Easy to process
- Excellent for soft soldering
- Good resistance to corrosion
- Not suitable for welding
- Cannot be brazed in a reducing atmosphere
- Poor machinability
