Sažetak
The recycling possibility of exploited ETP grade copper railway traction scrap has been evaluated in terms of reusing the materials of high Cu content for new traction equipment dedicated for modern railway and tram overhead lines based on CuNi2Si and CuZn37Ni1Si0,5 alloys. Firstly, the conducted research was focused on the qualitative and quantitative assessment of residual impurities of the scrap materials of carrying ropes and overhead contact lines. The main research part was the metallurgical synthesis and the impact of the said impurities on the chemical composition and selected properties of copper manufactured from scrap material.
