Highlights

  • Aluminum has relatively high values of thermal conductivity in the pure state, but any industry is focused on obtaining products from alloys close to eutectic compositions [2,3]

  • Thermal exchange is a physical property, that is why any alloying reduces the values of thermal conductivity (Fig. 1)

  • It is not possible to control the porosity in the laboratory using technologies of casting under air pressure, so the influence of the porous structure leads to a significant decrease in the thermal conductivity of the alloys compared to pure aluminum, the thermal conductivity of which was measured and fixed on 244,4 W/k·m

Summary

Introduction

Industrial interest in aluminum-based alloys is due to the desire of designers to reduce the weight of products and equipment, and to develop heat-conducting materials with high thermal conductivity of alloys [1]. Aluminum has relatively high values of thermal conductivity in the pure state, but any industry is focused on obtaining products from alloys close to eutectic compositions [2,3]. Thermal exchange is a physical property, that is why any alloying reduces the values of thermal conductivity (Fig. 1).
