Please refer to our FAQ for more information. The copper round bar, marked Cu-ETP, is made from electrolytically refined copper with a minimum purity of 99.9% and a maximum oxygen content of 0.04%. Due to its oxygen content, it is not suitable for welding because of the risk of hydrogen embrittlement. However, this material offers excellent cold and hot formability and is ideal for soft soldering. Brazing in reducing environments and machining are not recommended. You can purchase copper rods from Evek GmbH, a trusted supplier ensuring fast and reliable worldwide delivery. Thanks to its outstanding electrical and thermal conductivity, copper round bars are widely used in heating technology (such as radiators and heat exchangers), electrical machinery (like electric motors and coils), and various components (terminals, contacts). Copper rods are commonly used in: - Heating and cooling systems (heating and cooling elements) - Construction (decorative interior linings and facades) - Electrical and apparatus engineering - Shipbuilding and mechanical engineering - Electric cables and lines - Wire windings, chokes, and coils Key properties of copper round bars include: - Excellent formability both cold and hot - Superior processing characteristics - Outstanding solderability - Good resistance to corrosion - Not suitable for sweating or brazing in reducing atmospheres - Poor machinability Order copper rods conveniently through the Evek GmbH online shop at competitive prices.
