This copper round bar, designated Cu-ETP, is electrolytically refined and 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 excellent formability both hot and cold and is ideal for soft soldering. Brazing in a reducing atmosphere and machining are not recommended.
For purchasing copper rods, contact Evek GmbH. As a trusted supplier, we ensure fast and straightforward worldwide delivery.
Thanks to its high electrical and thermal conductivity, this copper round bar is widely used in heating technology (such as radiators and heat exchangers), electrical machinery (including electric motors and coils), and in the production of terminals and contact components.
Common applications for copper rods include:
- Heating and cooling systems (heating/cooling elements);
