Behaviour of Mechanical Properties of Aluminium Metal Matrix Composites on addition of Iron and Bronze by sand Casting Method

Composites are widely used in a variety of industries, including marine, aerospace, and automotive. The primary goal of this research is to look into the mechanical qualities of aluminum, iron, and bronze metal matrix composites made by sand casting since they are lightweight and have better mechanical properties like hardness and toughness. This paper discusses an aluminum composite experiment in which different proportions of iron and bronze were mixed in varying proportions to make samples. Three specimens were prepared, each comprised of Al + Fe and Al +Fe + Bronze, with Fe and bronze compositions varying and combined at 20%, 30%, and 40%, respectively. The results demonstrate that hardness and toughness rises as the percentage of iron in aluminum increases, and that in the case of iron and bronze, hardness increases as the percentage of composition increases from 20% to 40%, but toughness decreases till 40%.
