This copper round bar, designated 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 the risk of hydrogen embrittlement, this material is not suitable for welding. It offers excellent cold and hot formability and is ideal for soft soldering, but is not recommended for brazing in a reducing atmosphere or for machining.
To purchase copper rod, contact Evek GmbH. We are a trusted supplier offering smooth, worldwide delivery.
With its high electrical and thermal conductivity, this round copper bar is commonly used in heating technology (such as radiators and heat exchangers), electrical machinery (motors, coils), and various components (including terminals and contacts).
