The copper round bar (Cu-ETP) is made from high-purity, electrolytically refined copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to the oxygen content, this material is not suitable for welding (risk of hydrogen embrittlement). However, it offers excellent cold and hot workability and is ideal for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
For purchasing copper rods, contact Evek GmbH. As a trusted supplier, we ensure smooth and reliable worldwide delivery.
Thanks to its outstanding electrical and thermal conductivity, copper round bar is widely used in heating systems (radiators, heat exchangers), electrical machinery (motors, coils), and components like terminals and contact carriers.
Typical applications include:
- Heating and cooling systems (heating/cooling elements)
- Construction (decorative cladding and facades)
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings, chokes, and coils
Key characteristics of copper round bar:
- Excellent cold and hot formability
- Very good processing properties
- Excellent for soft soldering
- Good resistance to corrosion
- Not suitable for welding
- Not suitable for brazing in reducing atmospheres
- Poor machinability
