In recent years, many experiments have been devoted to additive technologies and their applications. In the present manufacturing scenario, aluminum-based metal matrix composites are widely used in various industrial divisions especially in automobiles, aircraft, marine, and mineral processing divisions due to its high tensile, impact, and hardness values. Although, several compositions are still remaining to research for enhancing the mechanical behavior of aluminum-based hybrid composites. In this direction, present research is based on the development of pure aluminum (Al-1100) based composites through stir-casting process with different mass fractions of zirconium diboride and alumina reinforcement such as 7% Al2O3−3%ZrB2, 6%Al2O3−9%ZrB2, 5%Al2O3−5%ZrB2, 7.5%Al2O3−7.5%ZrB2. Further, obtained performs were converted into specimens as per ASTM standards and Brinell hardness numbers, as well as impact strengths, were investigated. Increase in the percentage contents of ZrB2 results improved shining nature and reduced ductility of composites at the initial investigation. Also, improved corrosion resistance and mechanical behavior noted from newly developed performs.
