Abstract

The paper compares the properties of copper and its alloys with those of other materials. Copper is one of the most frequently used materials in electrical engineering, precisely due to its combination of electrical and mechanical properties, as well as its economic acceptability. It is primarily employed in the manufacturing of conductors. The aim of this study is to examine the use of copper as a conductor in comparison to some other materials or alloys for the same purpose. The measurement results demonstrate that copper has the best electrical conductivity among the materials tested. Additionally, it has been observed that the addition of impurities to copper degrades the essential electrical properties required for its use as a conductor. To assess the properties of copper, steel, and steel materials, a test model equipped with all the necessary measuring and testing equipment was employed.
