Conductor materials Most of our conductor material is copper (Cu). For the production of our wires we mainly use Cu-ETP1 (oxygenic copper) and Cu-OF 1 oxygen-free copper for special applications (e. g. hydrogen resistance). In addition to pure copper we also process a variety of copper alloys for special applications. Extract from EN 1977 – copper and copper alloys – raw wire made of copper Symbol Material number Melting point Oxygenic (tough-pitch) copper with an electrical conductivity in the soft condition Oxygen-free copper, non-deoxidized Cu-OF1 High-purity copper, largely free of elements...
