Al LM13 alloy reinforced with MgO particulates of 0–10wt% in terms of 2wt% were developed by the stir casting technique and the prepared samples were characterized on the basis of microstructure, Brinell hardness, XRD, and SEM. The hardness test indicated increased hardness of the MMC as the MgO particulate percentage increased. Optical microscope studies indicate the MgO particulate distributed randomly in the Al LM13 matrix. The presence of MgO was also identified in XRD. The wear performance of Al-LM13/MgO composite was examined on pin-on-disk equipment. The experimental studies on the MgO particulate increased the wear rate and decreased proportionately indicating the active role of the MgO particulate in reducing the wear. SEM suggests the presence of adhesive and abrasive wear mechanism with evidence of transfer films. The development in the wear resistance is due to the presence of MgO particulates in the Al LM13 matrix alloy.
