- The Cedynia Rolling Mill Division of KGHM Polska Miedz S.A. produces oxygen-free, silver-bearing Cu rod in a structurally cast state. At the customer’s request it is possible to produce CuAg(OF) silver-bearing rods in a non-standard way.
- The surface of the oxygen-free, silver-bearing copper rod is smooth and clean without cracks and micro holes, and is coated with a synthetic wax layer to protect the surface against oxidation during transport and storage (application of the synthetic wax layer is optional at the customer’s request).
- The oxygen-free, silver-bearing copper rod has an enhanced resistance to heat-related abrasion. Thanks to trace amounts of oxygen (max. 5 ppm) the rod has excellent drawability.
- The Cedynia Rolling Mill Division of KGHM Polska Miedz S.A. holds an Integrated Management System Certi cate conforming to the following standards: PN-EN ISO 9001:2001, PN-EN ISO 14001:2005 and PN-N 18001:2004 for the products it manufactures.
