The Aluminium 6063 have found wider applications in architectural fabrications, frames, pipe and tubing because of their intrinsic properties The Mechanical behavior of Aluminium alloy 6063 metal matrix composites (AMMC) reinforced with Borosilicate powder of 75 microns is investigated in this study. The Metal Matrix Composites (MMC's) were prepared using various percentages of borosilicate reinforcements of 0, 2.5, 5, 7.5 and 10 % by wt. The main aim of the research was to determine the impact of borosilicate powder (75 microns) on the mechanical behavior of Al 6063. Mechanical tests such as tensile test, Vickers micro hardness measurements and compression tests were performed on the produced composite samples to determine the influence of the powder in the Aluminium alloy. The test results of the reinforced samples were compared with non-reinforced samples. By comparing all the test values it is inferred that AA 6063 has better properties when reinforced with 7.5% of 75micron size borosilicate reinforcements.
