This copper round bar, designated as Cu-ETP, is made from electrolytically refined, oxygenated copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to hydrogen embrittlement, this material is not suitable for welding. It features excellent cold and hot formability and is ideal for soft soldering. However, hard soldering in a reducing atmosphere and machining are not recommended.
To purchase copper rods, please reach out to Evek GmbH. As a trusted supplier, we ensure reliable and straightforward worldwide delivery.
Thanks to its outstanding electrical and thermal conductivity, copper round rod is commonly used in heating technology (such as radiators and heat exchangers), electrical machines (like electric motors and coils), and various components (such as terminals and contact carriers).
Typical applications for copper rod include:
