The copper round bar, Cu-ETP, is an electrolytic tough pitch copper with a minimum copper content of 99.9% and a maximum oxygen content of 0.04%. Due to its composition, it is not suitable for welding because of the risk of hydrogen embrittlement. The material offers outstanding cold and hot forming abilities and is ideal for soft soldering. However, hard soldering in a reducing atmosphere and machining are not recommended.

Thanks to its excellent electrical and thermal conductivity, round copper rod is widely used in heating technology (such as radiators and heat exchangers), electrical machinery (like electric motors and coils), and various components (such as terminals and contact carriers).
Applications for copper rods include:
- Heating and cooling systems (heating and cooling elements);
- Construction (decorative interior cladding, facades);
- Electrical and apparatus engineering;
- Shipbuilding and mechanical engineering;
- Electrical wiring;
- Wire windings, chokes, and coils.
Main features of round copper rod:
- Excellent formability in both cold and hot states;
- Great processing characteristics;
- Very good for soft soldering;
- Good resistance to corrosion;
- Not suitable for welding;
- Cannot be brazed in a reducing atmosphere;
- Poor machinability.
