The copper round bar 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. However, it offers excellent cold and hot forming capabilities and is ideal for soft soldering. Hard soldering in a reducing atmosphere and machining are not recommended.
For purchasing copper rods, contact Evek GmbH. We are a dependable supplier offering smooth worldwide delivery.
