The copper round bar, designated as Cu-ETP, is an electrolytically refined, oxygenated copper alloy. It contains 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. It offers excellent hot and cold formability and is ideal for soft soldering, but not recommended for brazing in a reducing atmosphere or for machining.
For purchasing copper rods, reach out to Evek GmbH. As a trusted supplier, we ensure fast and straightforward worldwide delivery.
Thanks to its superior electrical and thermal conductivity, copper round rods are widely used in heating technology (radiators, heat exchangers), electrical machines (motors, chokes/coils), and components (terminals, contact carriers).
Common applications of copper rods include:
- Heating and cooling systems (elements, exchangers);
- Construction (decorative interior and facade cladding);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and chokes/coils.
Key properties of the round copper rod:
- Outstanding cold and hot formability;
- Excellent processing characteristics;
- Very good soft solderability;
- Good corrosion resistance;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
