Property evaluation of pumice particulate-reinforcement in recycled beverage cans for Al-MMCs manufacture

In this work, the effect of adding pumice powder to recycled beverage cans as reinforcement from 2 to 8 wt% in steps of 2 wt% was investigated. Manual stir casting technique was employed. Some mechanical (rockwell hardness, impact strength, tensile strength) and physical (density) properties were determined using standard methods. At 8 wt% pumice addition, an increment of 11.08% and 28.39% on hardness and tensile strength, respectively of the unreinforced recycled beverage can were recorded. However, the impact strength was reduced by 24.24%. The density was reduced by 39.51% compared to the unreinforced recycled aluminum. This composite material would find relevant applications in the development of light weight materials.
