Wire Rod

KGHM Polska Miedź S.A. "Cedynia" Copper Smelter Branch produces copper wire rod of 8 mm ± 0.4 mm and 10 mm ± 0.4 mm diameters under the continuous melting, casting and rolling method. The surface of the wire rod is cleaned by the alcohol method and coated with a synthetic wax layer which protects the surface against oxidation during transport and storage. The wire rod has a uniform microstructure, with uniform oxygen distribution. Oxygen content is low enough to ensure good drawability and a low recrystallisation temperature. The "Cedynia" Copper Smelter Branch of KGHM Polska Miedz S.A. holds a quality certificate conforming to PN-EN ISO 9001:2015; PN-EN ISO 14001:2015; PN-EN ISO 45001 issued by the Polish Research and Certification Centre, which covers the production of copper wire rod.

Cu-OFE Wire

"Cedynia" Copper Smelter Branch of KGHM Polska Miedź S.A in Orsk produces the oxygen-free copper wire under UPCAST technology. The installation was commissioned in 2006 thus increasing the production capacity of the plant by 15 K tonnes per year. UPCAST technology enables the production of wire of various diameters (8-12, 7-16-20-22-24-25 mm) and of wire from low-alloy copper with the addition of silver. This installation includes a cathode charging system, an induction melting furnace, an induction casting furnace, a casting machine with moulds and primary and secondary coolers for vertical casting along with 16 coiling machines.

Application

production of microwires,
enamel coated and/or Ag-, Sn-, Ni-plated copper wire,
fire-resistant safety cables,
low-alloy copper products,
CAT (category) 6 and 7 video and audio transmission cables

for drawing:
Cu-OFE wire with an oxygen content of <5ppm is resistant to hydrogen embrittlement. Trace amounts of oxygen ensure excellent drawability and a low recrystallisation temperature.

for extruding:
Cu-OFE wire is an ideal material for continuous flat or round extruding using the Conform® process.

for rolling:
Cu-OFE wire may also be rolled into flat or round sections.
