In the current research and investigations on mechanical behavior of multiple particles reinforced Al7075 alloy composites were studied. The composites were synthesized by using 3 wt. % of fly ash and 1 wt. % of red mud constant with 2, 4 and 6 wt. % of varying mica particles in the Al alloy using vortex method. The hybrid composites were subjected to microstructural and mechanical behavior analysis. Microstructural tests were done by optical microscopy and XRD. The mica, fly ash and red mud particles were comparatively dissipated and presences of these particles were studied by the XRD. The hardness and strength of composites have been improved with the advancement of different fortresses. There was slight reduction in the malleability of the Al7075 mix after the expansion of the fortifications. Particular break structures were found in the Al7075 alloy composites utilizing SEM.
