The copper round bar with the designation 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%. Due to the risk of hydrogen embrittlement, this material is not suitable for welding. It features excellent cold and hot formability and is ideal for soft soldering, but is not recommended for hard soldering in reducing atmospheres or for machining.
To purchase copper rod, reach out to Evek GmbH. We are a reliable supplier offering straightforward worldwide deliveries.
Thanks to its high electrical and thermal conductivity, round copper rod is commonly used in heating technology (such as radiators and heat exchangers), in electrical machines (like motors and coils), and for components including terminals and contact carriers.
Typical applications for copper rod include:
- Heating and cooling systems (heating/cooling elements);
- Construction (decorative elements for interiors and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and coils.
Key properties of copper round rod:
- Excellent cold and hot workability;
- Good processability;
- Outstanding soft soldering capability;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
