Increasing the strength of electrical aluminum 1370 by modifying carbon nanotubes with copper

This paper presents the results of a study of the structure and main mechanical characteristics of the electrical aluminum alloy 1370 used in the production of electrical wires after modification with carbon nanotubes (CNTs) and copper. It is shown that modification of the alloy with CNTs and copper in different ratios affects the physical and mechanical characteristics of the resulting castings, so the complex introduction of CNTs with copper provides an increase in strength by 25 MPa with a slight decrease in ductility (by 25–35 %). The results obtained allow us to conclude that the introduction of CNTs into the melt of electrical aluminum 1370 is a promising way to improve its mechanical characteristics.
