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
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).
