SiC reinforced Aluminum samples were produced by stir casting of liquid AA1200 aluminum alloy at 600650ºC casting temperature. 83µm SiC particles were rinsed in 10gl, 20gl and 30gl molar concentration of Sncl2 through cleaning times of 0, 60, 120, and 180 minutes. Some cast samples were tested for mechanical properties and some were subjected to heat treatment before testing. The SnCl2 rinsed SiC reinforced aluminum exhibited higher yield strength, hardness, stiffness and elongation which increases with cleaning concentration and time up to 120 minutes, compared to composite with untreated SiC. However, the impact energy resistance decreases with cleaning concentration and time. The improved properties were attributed to good wettability and mechanical adhesion at the fibermatrix interface. Quenching and annealing the composite samples further improve the tensileyield strengths, elongation, stiffness, hardness similar to those of the ascast samples.
