Abstract
The raw material for the production of Al-Mg-Si wires is wire rods, created in the Continuus Properzi line in temper T1 (cooled after forming at an elevated temperature and after natural aging). The general technologies for shaping the mechanical and electrical properties of Al-Mg-Si wire rods include two kinds: high- and low-temperature heat treatments. High-temperature heat treatment includes a homogenization process and a supersaturation process. Low-temperature heat treatment takes place after supersaturation and includes natural or artificial aging. This study shows how the amount of Mg and Si influences the mechanical and electrical properties of EN-AW 6101 wire rods after different kinds of heat treatments. As the general aim of this study was to determine the effect of the material’s temper on its mechanical and electrical properties, the research considered the initial parameters of the starting materials being examined. These parameters can be modified by selecting the chemical composition of the Al-Mg-Si alloy and the value of precipitation hardening obtained with artificial.

Summary
One of the conductor types of overhead transmission lines is homogeneous conductors made ofAl-Mg-Si alloy wires. One of the conductor types of overhead transmission lines is homogeneous conductors made of. Achieving high electrical conductivity and high tensile strength in the wires is possible by using a combination of heat treatment processes (supersaturation, aging) and deformation processes (drawing process). The traditional homogenization and quenching treatments of Al-Mg-Si alloys occur at a temperature above 500 ◦ C, and artificial aging occurs in the range of 100–200 ◦ C. Heat treatment procedures are carried out on the raw material continuously in a continuous casting and rolling line, such as continuously heat-treated alloy. Heat treatment procedures are conducted on wires. Most analysesb refer to heat treatment procedures for Al-Mg-Si wire, as in the series of works by Martinowa [1,2], which consider optimization problems in heat treatment procedures of
