Copper Wire Rod

Metraco S.A. offers copper wire rod of 8mm ± 0,4 mm diameter produced by KGHM Polska Miedź S.A. / “Cedynia” Copper Smelter Division by means of continuous melting, casting and rolling.

The wire rod’s surface is purified with use of the alcohol method and covered with synthetic wax, which prevents its surface from oxidizing when transported and stored.

The wire rod has a fine-grained structure, where oxygen is uniformly arranged. The oxygen content is low enough to ensure good ductility and low recrystallization temperature.

“Cedynia” smelter has a quality certificate compliant with PN-EN ISO 9001:2009, PN-EN ISO 14001:2005, PN-EN 18001:2004, issued by the Polish Centre for Testing and Certification, which pertains to, among others, manufacture of copper wire rod.
