Copper Round Steel

Premium Copper Round Steel – High Purity & Superior Machinability
Our copper round steel (round bar) is manufactured from high-grade electrolytic copper, ensuring a minimum copper content of 99.9%. These bars are characterized by their exceptional electrical and thermal conductivity, making them indispensable for power distribution and high-current engineering. With excellent cold and hot workability, our copper round bars are ideal for CNC machining, forging, and welding. Whether you need them for heavy-duty electrical connectors, switchgear components, or architectural hardware, our products provide consistent density and a smooth surface finish that meets the most rigorous industrial standards.
