The copper round bar with material designation Cu-ETP is made from electrolytically refined, oxygenated copper, containing at least 99.9% copper and a maximum of 0.04% oxygen. Due to the risk of hydrogen embrittlement, this material is not suitable for welding. However, it offers excellent cold and hot formability and can be easily soft soldered. Hard soldering in a reducing atmosphere and machining are not recommended.
To purchase copper rods, please contact Evek GmbH. As a trusted supplier, we ensure smooth worldwide deliveries.
Because of its high electrical and thermal conductivity, copper round bar is commonly used in heating technology (such as radiators and heat exchangers), electrical machinery (like motors and coils), and various electrical components (such as terminals and contact carriers).
Common applications include:
- Heating and cooling systems (elements for heating and cooling);
- Construction (decorative interior cladding and façades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and chokes/coils.
Main properties of round copper rod:
- Excellent hot and cold formability;
- Very good processing characteristics;
- Excellent for soft soldering;
- Good corrosion resistance;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
