| APPLICATION | A product for drawing on single- and multi-wire machines. Single wires and strands drawn from wire rod are used as conductors in electric cables and wires (e.g. enameled wires, automotive wires, connection cords, etc.). 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). |

Cu-OFE Wire
| product | Cu-OFE-8-CL, Cu-OFE-12,7, Cu-OFE-16, Cu-OFE-20, Cu-OFE-22, Cu-OFE-24, and Cu-OFE-25 wire |
| APPLICATION | for drawing: the Cu-OFE wire with oxygen content <3 ppm is resistant to hydrogen embrittlement (hydrogen-induced cracking). The negligible amount of oxygen ensures very good drawability and a low recrystallization temperature. The very good drawability of the wire allows for very deep drawing, down to diameters of less than 0.1 mm (micro wire). Wires drawn from the Cu-OFE wire wires are used as copper conductors, which can be additionally coated with Ag, Sn, or Ni. These types of conductors are used in enameled cables, as well as specialty cables and wires, e.g. in safety cables with increased fire resistance (for IT systems and nuclear power plants), as well as in cat. 6 and 7 cables for sound and video transmission. for extrusion: the Cu-OFE wire is an ideal material for continuous extrusion into flat and shaped profiles using the Conform® process. for rolling: the Cu-OFE wire can also be rolled into flat profiles and sections. |

| CUSTOMER BENEFITS | The primary benefit is the purchase and use of a product with a guaranteed stable and very high quality. The production process is carried out with high technological discipline and using feedstock of selected high quality, i.e. cathodes produced in KGHM. The unique technological characteristics of the process make it possible to avoid inclusions and maintain high product uniformity. 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. |
