        abstract = {The development of advanced materials with superior mechanical properties has gained significant attention in engineering and industrial applications. Consequently, finding methods to use them that are both productive and environmentally safe has always been a hurdle for scientific applications. The aim of the study was to examine the mechanical properties of tungsten carbide (WC) and Coconut Shell Fly Ash (CSFA) reinforced aluminum matrix composites. The composites are synthesized using a stir-casting technique, ensuring uniform distribution of the reinforcements within the matrix. Mechanical properties, such as tensile strength, hardness, and impact resistance, are evaluated and compared to the unreinforced Al7075 alloy. The optimal reinforcement composition of 6 wt. % WC and 3 wt. % CSFA resulted in a maximum tensile strength of 157.38 MPa, representing a 30% increase over unreinforced Al7075. However, this enhancement was accompanied by a decrease in ductility, highlighting the trade-off between strength and ductility commonly observed in composite materials. Additionally, the impact energy reached a peak of 0.916 J/mm² at the same optimal composition, but further increases in reinforcement content led to a decline in impact energy due to micro-porosity. The Flexural strength improved from 61.5 MPa at 0 wt% of WC-CFSA to 92.1 MPa with 9 wt. % WC and 3 wt. % CSFA, same as the hardness of the composites also showed a significant increase, achieving a maximum value of 86.16 HRB      with 9 wt. % WC and 3 wt. % CSFA, attributed to improved load bearing capacity and reduced porosity. These findings emphasize the importance of optimizing reinforcement composition to enhance the mechanical properties of Al7075 composites.},
