The copper round bar, designated as Cu-ETP, is an electrolytically refined, oxygen-containing copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to potential hydrogen embrittlement, this material is not suitable for welding. It offers excellent formability both hot and cold 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, please reach out to Evek GmbH. We are a reliable supplier and offer fast, worldwide delivery.
Owing to its high electrical and thermal conductivity, copper round bar is commonly used in heating technology (such as radiators and heat exchangers), electrical machinery (motors, chokes/coils), and components like terminals and contact carriers.
Typical applications for copper rods include:
- Heating and cooling systems (elements for heating and cooling);
- Construction (decorative applications for interiors and facades);
- Electrical engineering and equipment manufacturing;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings and chokes/coils.
Main properties of copper round bar:
- Excellent hot and cold workability;
- Good processing characteristics;
- Outstanding soft soldering capabilities;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
