4. Conclusions Manufacturing aluminum matrix composites using sea sand reinforcement particles with the stir casting method was successfully produced. A composite with sea sand reinforcement particles has a higher density compared to composites with alumina and SiC. The porosity produced on composites with sea sand particles is lower than that of composite porosity with other reinforcing particles. The composites with sea sand reinforcement particles resulted in higher hardness than composites with alumina and SiC reinforcement particles. Composites with sea sand reinforcement particles are possible to be developed. This work can be continued with pre-treatment of the sea sand particles that improve the particle’s wettability .
