Our copper round bar, designated as Cu-ETP, is an electrolytically refined copper with added oxygen. It contains at least 99.9% copper and a maximum oxygen content of 0.04%. Due to its susceptibility to hydrogen embrittlement, this material is not suitable for welding. However, it offers excellent formability both hot and cold and is ideal for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
To purchase copper rods, reach out to Evek GmbH. We are a reliable supplier, offering straightforward worldwide delivery.
Thanks to its outstanding electrical and thermal conductivity, copper round bar is commonly used in heating systems (such as radiators and heat exchangers), electrical machines (like motors and coils), and for making electrical components (including terminals and contact carriers).
Typical applications of copper rod include:
- Heating and cooling elements
- Construction projects (e.g., decorative interior and facade cladding)
- Electrical and apparatus engineering
- Shipbuilding and mechanical engineering
- Electrical wiring
- Wire windings, chokes, and coils
Main features of the round copper rod:
- Excellent cold and hot forming capability
- Good workability
- Outstanding soft soldering properties
- Good resistance to corrosion
- Not suitable for welding
- Cannot be brazed in a reducing atmosphere
- Poor machinability
