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 potential 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 a reducing atmosphere and machining are not recommended.
To purchase copper bars, contact Evek GmbH. As a trusted supplier, we ensure smooth worldwide delivery.
Thanks to high electrical and thermal conductivity, copper round bars are commonly used in heating technology (radiators, heat exchangers), electrical machines (motors, chokes/coils), and various components (terminals, contact carriers).
Typical applications include:
- Heating and cooling systems (heating and cooling elements)
- Construction (decorative interior and facade cladding)
- Electrical and equipment engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings, chokes, and coils
Key properties of copper round bar:
- Excellent cold and hot formability
- Very good processing qualities
- Outstanding soft solderability
- Good resistance to corrosion
- Not weldable
- Cannot be brazed in a reducing atmosphere
- Poor machinability
