This copper round bar, designated Cu-ETP, is electrolytically refined and oxygenated copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to the risk of hydrogen embrittlement, this material is not suitable for welding. However, it is highly workable both cold and hot, and is well-suited for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
To purchase copper rods, please contact Evek GmbH. As a trusted supplier, we offer reliable worldwide shipping.
With excellent electrical and thermal conductivity, copper round rods are widely used in heating technology (such as radiators and heat exchangers), electrical machines (motors, chokes/coils), and various components (terminals, contacts).
Common applications of copper rods include:
- Heating and cooling systems (elements and exchangers)
- Interior and exterior construction (decorative cladding and facades)
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings and coils/chokes
Key properties of the copper round rod:
- Excellent cold and hot forming capabilities
- Easy to process
- Very good for soft soldering
- Good resistance to corrosion
- Not suitable for welding
- Cannot be brazed in a reducing atmosphere
- Poor machinability
