In this study, materials AA-1070, AA-6101, Fe, aluminum clad steel (ACS) and aluminum clad steel (CS) tube used in manufacturing of aerial bare conductors for transmission lines have been presented by analyzing their interactions with processing tools of machines and friction properties of each other. To detect interactions of conductor metal and processing machine, analyses of samples collected from their manufacturing plant were performed by means of SEM and optical microscope. Tribological properties of components of bare conductors were analyzed experimentally under dry sliding to illustrate processing damaging of machines. Five different samples were carried out on pin on disk wear tester for that purpose. The effects of heat treatment on the tribological behavior of the samples were also investigated. As a conclusion, it has been detected that ACS wire clad with AA-1070 and Zinc coated steel wire can be preferred as high wear resistance metal components. On the other hand, under dry sliding condition, samples prepared from the materials AA-6101 (heat treated) and AA-6101 (non-treated) have lower friction coefficient values than other samples. These conductor materials are very vulnerable due to external effects and processing tooling. It requires perfect management of processing of the material in the plant.
