Metallographic analysis and thermal conductivity analysis of series of light aluminum alloys with silicon content from 0 to 12 % (by weight) and additionally alloyed with iron 1 % (by weight) were carried out. It is shown that with an increase in the silicon content in the alloy above 4–6 % (by weight), the size of silicon crystals increases significantly with a simultaneous increase in the values of thermal conductivity. The article assesses the effect of iron on thermophysical properties and shows the correlation of thermal conductivity at different temperatures with the morphology of silicon in alloys with silicon content from 0 to 12 % (by weight) and additionally alloyed with iron 1 % (by weight). It is shown that alloy with a silicon content of 4 % by weight has a balanced reserve of thermophysical properties due to the structural features of the morphology of the components.
