This copper round bar, designated 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%. Because of possible hydrogen embrittlement, this material is not suitable for welding. It offers excellent cold and hot formability and is ideal for soft soldering. Hard soldering in reducing atmospheres and machining are not recommended.
To purchase copper rod, contact Evek GmbH. As a trusted supplier, we ensure smooth worldwide delivery.
Thanks to its high electrical and thermal conductivity, copper round bar is commonly used in heating technology (such as radiators and heat exchangers), electrical machinery (motors, coils), and components like terminals and contacts.
Applications for copper rod include:
- Heating and cooling systems (elements and exchangers)
- Construction (decorative elements for interiors and facades)
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings, chokes, and coils
Main properties of the round copper rod:
- Excellent cold and hot formability
- Great processing characteristics
- Excellent for soft soldering
- Good resistance to corrosion
- Not suitable for welding
