This copper round bar (Cu-ETP) is made from electrolytically refined, oxygen-containing copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to the risk of hydrogen embrittlement, it is not suitable for welding. The material offers outstanding cold and hot formability and is ideal for soft soldering. However, it is not recommended for hard soldering in a reducing atmosphere or for machining.
To purchase copper rods, contact Evek GmbH. As a reliable supplier, we provide smooth, worldwide delivery.
Thanks to its excellent electrical and thermal conductivity, copper round bar is widely used in heating technology (radiators, heat exchangers), electrical equipment (motors, coils), and components such as terminals and contact carriers.
Common applications include:
- Heating and cooling systems (heating/cooling elements);
- Construction (decorative interior cladding and facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and coils.
Main properties of the copper round rod:
- Excellent cold and hot formability;
- Easy to process;
- Excellent soft solderability;
- Good resistance to corrosion;
- Not suitable for welding;
- Not suitable for brazing in reducing atmosphere;
- Poor machinability.
