In this research work, 3 wt % of tungsten trioxide (WO3) particulates are used to reinforce the Al5Mg5Zn alloy. For the development of this particulate, reinforced Al metal matrix composite, two step stir casting processing route is used due to its simplicity and cost effectiveness. The Brinell hardness, impact toughness, and sliding wear resistance properties of the casted Al5Mg5Zn alloy and developed Al5Mg5Zn + 3%WO3 composite are investigated according to ASTM standards and their results are compared. The worn surfaces of the test sample are analysed by using optical microscopy to obtain the pattern of the dry sliding wear. The results show that the addition of 3 wt % WO3 particulates improved the hardness and sliding wear resistance of the Al5Mg5Zn alloy and diminished the value of impact toughness.
