Aluminium base alloys have mostly been used as structural components and aerospace

application due to light weight and environmental resistance. However aluminium pure

powder product’s applications were limited despite many potential merits. The present

study aims to develop an aluminium matrix composite with nanoparticle silica sand.

The nanoparticle silica sand with average particle size of less than 100nm was produced

by several stages of ball mill and heating combinations. Aluminium matrix composites

with 2, 4, 6 and 8 wt.% of nanoparticles silica sand were developed through powder

metallurgy technique. It was observed that addition of 8 wt.% nanoparticles silica sand

was able to increase the hardness and tensile strength of the composites up to 50 HRB

and 323.77 MPa, respectively. Despite of decreasing in its density the composite

showed improvement in mechanical properties.
