Abstract: In present study, Al7075-Beryl synthesized by using a stir casting technique. The different weight percentage of Beryl incorporated are 2Wt.% to 8 Wt.% in steps of 2 Wt.%. The effect of Beryl particles integration on hardness and tensile strength response on Al7075 were investigated. It is demonstrated that Beryl particles distributed homogeneously in the Al7075 matrix acts as effective reinforcement to enhance the mechanical properites. Compared to base Al7075 matrix, Al7075- 6 wt.% Beryl composites exhibited higher yield strength of 47.42%, ultimate tensile strength of 44.08% and Al7075-8Wt.% enhancement in hardness of 27.71% when compared to momlithic Al7075. As cast Al7075 alloy and Al7075-Beryl composites were microstructurally characterized with scanning electron microscopy (SEM), Energy dispersive spectrum (EDS) and X-ray diffraction (XRD). Microstructure study through scanning electron microscope study reveals that the uniform distribution reinforcement Beryl into Al7075 matrix. The Al7075- Beryl.
