The copper round bar (Cu-ETP) 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 the risk of hydrogen embrittlement, this material is not suitable for welding. It offers excellent cold and hot formability, and is ideal for soft soldering, but not recommended for brazing in a reducing atmosphere or for machining.
For purchasing copper rods, contact Evek GmbH. As a trusted supplier, we provide reliable worldwide delivery.
With its high electrical and thermal conductivity, copper round rod is used in heating systems (radiators, heat exchangers), electrical machines (motors, coils), and electrical components (terminals, contacts).
Common applications for copper rods include:
- Heating and cooling technology (heating and cooling elements)
- Construction (decorative elements for interiors and facades)
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Windings for wires and coils
Key features of copper round rods:
- Excellent cold and hot formability
- Easy to process
- Very good for soft soldering
- Good corrosion resistance
- Not suitable for welding
- Cannot be brazed in a reducing atmosphere
- Poor machinability
