This research represents an advancement of the preceding study, specifically examining the Impact of SiC
Addition on Resistance, Wear, and Hardness through Stir Casting of Aluminum Matrix Composites. Within this
investigation, the identical casting technique, the Stir Casting Method, was employed, with a focus on Al-Si aluminum
alloy incorporating SiC and Mg reinforcement. The composition of the raw materials mixture (Al-Si aluminum alloy) was
60%, while the adhesive materials mixture comprised 40%, consisting of 20% SiC and 20% Mg. The pour temperature
utilized in melting the raw and adhesive materials in furnaces was set at 600°C and 700°C. Subsequently, the molten
specimen samples were poured into mold patterns and further processed for hardness and impact tests. Impact test results
were obtained for specimen samples with a 60% Al-Si alloy, combined with a mixture of 20% SiC and 20% Mg adhesives
at a cast temperature of 600°C, yielding an Impact Energy of 68.60 J and Impact Strength of 0.85 J/m. Meanwhile, specimen
samples at a cast temperature of 700°C exhibited an Impact Energy of -95.40 J and Impact Strength of -1.19 J. Hardness
test results for specimen samples of the 60% Al-Si alloy, combined with a mixture of 20% SiC and 20% Mg adhesives at
a cast temperature of 600°C, showed an average hardness of 65 kgf/mm. On the other hand, specimen samples at a cast
temperature of 700°C displayed an average hardness of 50 kgf/mm.
