Copper and steel-copper composite materials with high electrical properties

матеріал, структура. Experimental samples of steel-copper and copper composite conductors, including those from copper waste, were obtained according to the developed technology. The physical and operational properties of the copper composite material were investigated, special attention was paid to the wear resistance, which was tested as part of the working pantograph of the electric train, and the electrical conductivity of the obtained copper composite was investigated. It is shown that the electrical conductivity of the composite material made of copper is higher in the range of operating temperatures of the pantograph, and the wear resistance is much higher than that of the sample made of standard copper material.
