Copper Round Bars are mainly made from high-purity copper (usually over 99.9%) and may include small amounts of alloying elements like silver or phosphorus to enhance their properties. These bars boast impressive mechanical characteristics, with tensile strength ranging from 210 to 370 MPa, and a high elongation rate that varies depending on the temper. They also offer excellent thermal and electrical conductivity, good corrosion resistance, and remarkable workability. With solid fatigue strength, Copper Round Bars are perfect for both cold and hot working operations. Their robust mechanical profile ensures reliable performance in even the most demanding industrial applications.

Copper Round Bars typically do not require corrosion protection coatings due to their inherent corrosion resistance, but coatings may be used in specific environments for added protection.
Yes, Copper Round Bars can be welded using appropriate techniques, such as TIG or MIG welding, with careful control of heat to prevent oxidation.
To choose the right Copper Round Bar, consider factors such as required strength, conductivity, corrosion resistance, and the specific application needs.
Thanks to their outstanding electrical and thermal conductivity, corrosion resistance, and mechanical strength, Copper Round Bars find widespread use across various sectors. In the electrical industry, they are essential for manufacturing conductors, switchgear components, and busbars. The plumbing and HVAC industries rely on them for fittings, valves, and connectors. In construction, they are utilized in roofing, structural elements, and decorative features. The marine industry benefits from their corrosion-resistant fittings and hardware. Additionally, Copper Round Bars play a crucial role in automotive, aerospace, and telecommunications sectors, where high performance and reliability are paramount.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
