This study presents a comparative investigation of the tribological behaviour and microstructural characteristics of two different alloys, namely, 77.3% Al–1.8% Fe–16.7% Si (Al–Si-based alloy) and 62.9% Al–14.4% Fe–16.9% Si (Al–Fe–Si-based alloy). High temperature alloys are fabricated by stir-casting technique. Tribology analysis is conducted to assess wear, crack formation, and cavity zones for both alloys using scanning electron microscopy. In addition, optical micrography is used to examine their microstructures. The results reveal significant differences between the two alloys: with the high concentration, Si-alloy specimen exhibits higher Vickers hardness and superior wear resistance compared to the low-concentration Si-alloy specimen. Optical micrographs confirm a well-defined grain distribution for the former alloy and a similar homogeneous microstructure for the latter.
