Snailshells and discarded aluminium based alloys have low economic values and are mostly considered as environmental pollutants. However, recycling them for further application in material processing can create significant economic value. Snailshell particles are known for their hardness, and thus useful as good alloying element for aluminium based pistons. In this paper, the potential of snailshell particles as reinforcement agent in Al/snailshell particulate composites is reported. Snailshell particles of weight fraction ranging from 16 to 48 wt.% and size of 200, 400 and 600 μm were added to aluminium obtained from discarded aluminum pistons during casting. The microstructures of the composites were examined under optical metallurgical microscope. The tensile strength and hardness were measured based on the experiments conducted using Box Behnken design. The results showed that, at 48 wt.% and 600 μm particle size, the tensile strength and hardness are maximum (236 MPa and 48.3 HRF, respectively) compared to the tensile strength of 92.4 MPa and hardness of 29.2 HRF for the unalloyed samples. These increments are attributed to the uniform distribution of snailshells in the ductile aluminum matrix. It is concluded that both the tensile strength and hardness are significantly enhanced, and snailshells can be used as a low-cost reinforcement for engineering applications.
