Copper Round Bars are meticulously crafted cylindrical rods made from high-purity copper, known for their excellent electrical and thermal conductivity, as well as exceptional resistance to corrosion. These bars are produced through a precise manufacturing process, which includes melting premium copper, casting it into billets, and shaping it into round bars via extrusion or rolling. To enhance their mechanical properties and surface quality, additional steps such as annealing and finishing (like polishing or pickling) are applied. The resulting bars are prized for their consistent dimensions, smooth surface finish, and reliable performance, making them suitable for a wide variety of demanding applications. The material used in copper round bars is typically 99.9% pure copper, such as Electrolytic Tough Pitch (ETP) or Oxygen-Free High Conductivity (OFHC) copper. These grades offer excellent conductivity and are chosen based on application requirements. The bars are available in a variety of diameters ranging from 6mm to over 200mm, and can be supplied in lengths up to 6 meters or as per customer specifications. Key technical properties include high tensile strength (200–400 MPa), elongation ranging from 20% to 45%, and exceptional electrical conductivity—up to 101% IACS (International Annealed Copper Standard). Available in soft, half-hard, and hard tempers, they provide versatility across industries. Copper round bars are widely…
