<div>Demands for new materials with superior properties are rising as technological
advancement is speeding up globally. Composite materials are gaining popularity
due to their enhanced mechanical properties over metal and alloys. Aluminum
metal matrix composites (MMCs) are becoming popular in several areas of
application such as aerospace, automobile, armed forces, and other commercial
applications due to their lightweight, increased strength, better fracture
toughness, stiffness, corrosion resistance, and cost-effectiveness. The present
study reviews the effects of different reinforcements on MMC materials. The main
aim of the present work is to give a clear idea to the readers about the role of
individual reinforcement in Al7075-based MMCs. Also, the details of weight% and
size of different reinforcement are provided, which will help the readers in
their future works. It has been observed that inorganic reinforcements give
better mechanical and wear properties to composite materials. For better wear
properties, self-lubricating types of reinforcements are more useful.</div>
