This copper round bar (Cu-ETP) is electrolytically refined and oxygenated, with a copper content of at least 99.9% and an oxygen content up to 0.04%. Due to possible hydrogen embrittlement, this material is not suitable for welding. However, it offers excellent cold and hot formability and is well-suited for soft soldering. It is not recommended for brazing in a reducing atmosphere or for machining.
To purchase copper rods, please contact Evek GmbH. As a trusted supplier, we ensure fast, hassle-free global delivery.
With high electrical and thermal conductivity, copper round rods are widely used in heating technology (radiators, heat exchangers), electrical machinery (motors, chokes/coils), and as components (terminals, contact holders).
Common uses for copper rod include:
- Heating and cooling applications (heating/cooling elements)
- Construction (decorative interior cladding and facades)
