<div>Recent developments in manufacturing techniques and the development of Al7075
metal matrix composites (MMCs) with reinforcements derived from industrial waste
have been steadily gaining popularity for aerospace and automobile applications
due to their outstanding properties. However, there are still a lot of
limitations with these composite materials. A great deal of research has been
done to create new Al7075 MMC materials with the use of economic fly ash (FA)
that possesses superior mechanical properties, corrosion resistance, density,
and cycle cost. This review outlines different synthesis techniques used in the
development of Al7075 MMCs using stir casting. Effects of FA along with other
reinforcements on the mechanical, wear, machining, and microstructural
properties of the composite are also discussed. Finally, a summary of the
application of FA-based MMCs and a recap of the previous discoveries and
challenges are reported. Future scope and potential areas of application are
also discussed. This will inspire the potential researchers to understand the
benefits of using FA as a reinforcement and carry out researches on this area
that will be beneficial for the society economically as well as
environmentally.</div>
