Abstract
The dynamic increase in copper and copper alloy use is closely associated with the search for cathode copper substitutes in various production processes. Within the article, research was carried out on copper scraps in the form of worn-out railway catenaries, which were originally produced from Cu-ETP copper. This article assesses the industrial potential of this kind of scrap for direct use in modern production technologies of copper alloys. However, due to its characteristics, resulting from many years of wear and potential exposure to surface pollution, the assessment of potential use was made based on surface contamination influence on the chemical composition of the base material after melting and solidification (simulation of traditional casting processes). Conducted research works showed that the main contaminants of used traction copper scrap are Fe, Pb, and S and also other elements in trace amounts. The amount of copper contamination detected after direct remelting of worn catenary conductor resulted in a decrease in copper conductivity to the level of 49.3 MS/m (approx. 85% IACS). Moreover, the conducted research revealed that, due to the geometrical structure of the catenary conductor, it is partially possible to recover clean copper, characterized by high electrical conductivity (58.3 MS/m) and low impurity content.
