In this study, the metal–matrix composites of an aluminum–silicon based alloy (LM6) with Lead oxide glass particles with % addition of 2.5%, 5%, 7.5%, and 10% were produced using a sand casting technique. The variation in composition, hardness, tensile strength and microstructure properties were examined. The change in volume of Silicon and lead content was examined in the spectroscopic analysis. The tensile strength and hardness of the composite increased with increasing the % reinforcement. The microstructure shows the formation silicon dendrites and the dispersion of the glass particle.
