Contact via the website or by phone at +48 76 74 78 800 The sale of the product is carried out from KGHM’s Head Office in Lubin by the Department of Intermediate Products. Compared to the wire rod made using the “Contirod®” technology, the customer gets a product with a smaller diameter tolerance and a surface without scales. The unique technological characteristics of the process make it possible to avoid inclusions and maintain high product uniformity. The production process is carried out with high technological discipline and using feedstock of selected high quality, i.e. The primary benefit is the purchase and use of a product with a guaranteed stable and very high quality. Each coil is protected by thermo-shrinkable polyethylene film against adverse weather conditions. It is delivered on wooden pallets, secured with steel straps. The oxygen-free copper wire is supplied in coils weighing up to 4.0 mt, in one section. On request, the wire can be produced with a surface without wax. Tensile strength (200 mm): 180 ± 10 N/mm2Ĭlean and smooth without cracks or pores, coated with a layer of synthetic wax that protects the surface from oxidation during transport and storage. 10 bends in a bending test, Cu-OFE-12.7 - no cracks in a single bending test. Resistance to hydrogen embrittlement: Cu-OFE-8 - min. The wire is made from selected quality cathodes produced at KGHM divisions in the Cu-CATH-1 grade, under the HMG-B and HMG-S brands.Ĭonductivity at 20 ✬: min. 3 ppm, maximum contamination level 25 ppm 6 and 7 cables for sound and video transmission.įor extrusion: the Cu-OFE wire is an ideal material for continuous extrusion into flat and shaped profiles using the Conform® process.įor rolling: the Cu-OFE wire can also be rolled into flat profiles and sections.Ĩ mm ☐,4 12,7 mm ☐,4 16 mm ☐,4 20 mm ☐,6 22 mm ☐,6 24 mm ☐,6 and 25 mm ☐,8 in safety cables with increased fire resistance (for IT systems and nuclear power plants), as well as in cat. These types of conductors are used in enameled cables, as well as specialty cables and wires, e.g. Wires drawn from the Cu-OFE wire wires are used as copper conductors, which can be additionally coated with Ag, Sn, or Ni. The very good drawability of the wire allows for very deep drawing, down to diameters of less than 0.1 mm (micro wire). The negligible amount of oxygen ensures very good drawability and a low recrystallization temperature.

The “Cedynia” smelter holds a quality certificate in accordance with PN-EN ISO 9001:2015 PN-EN ISO 14001:2015 PN-EN ISO 45001, issued by the Polish Center for Testing and Certification, which covers, among other things, the production of copper wire rod.Ĭu-OFE-8-CL, Cu-OFE-12,7, Cu-OFE-16, Cu-OFE-20, Cu-OFE-22, Cu-OFE-24, and Cu-OFE-25 wireįor drawing : the Cu-OFE wire with oxygen content <3 ppm is resistant to hydrogen embrittlement (hydrogen-induced cracking). The production program includes diameters of 8 mm ± 0.4 mm and 10 mm ± 0.4 mm. The “Cedynia” Copper Smelter Division of KGHM Polska Miedź S.A in Orsk produces the copper wire rod using the continuous melting, casting, and rolling method.

The wire rod is supplied in coils of approx. The oxygen content is low enough to ensure good drawability and a low recrystallisation temperature. The wire rod has a fine-grained structure, with uniform oxygen distribution. Tensile strength (200 mm): 225 MPa ± 5 MPa Spiral elongation (EN 12893): 450 ± 10 mm, or alternative examination - AR test: min. The wire rod is mainly produced from cathodes made at KGHM’s divisions in the Cu-CATH-1 grade, under the HML, HMG-B, and HMG-S brands.Ĭonductivity at 20 ✬: min. Impurities at a maximum of 30 ppm O2 = 150-190 ppm (max. The wire rod produced at KGHM can be drawn in a wide range of diameters on single-wire machines (minimum diameter of less than 0.1 mm) as well as multi-wire machines (minimum diameter of 0.1 mm). enameled wires, automotive wires, connection cords, etc.).
Single wires and strands drawn from wire rod are used as conductors in electric cables and wires (e.g.
