Experimental works on SiC based technology has gained more importance in aerospace, nuclear, automobile, chemical and cryogenic applications. In the present work SiC particles of size of 10% is dispersed in a matrix of aluminium alloy (Al 6063) with varying weight fractions of 3, 6, 9 and 12% by using the process of stir casting. The molten MMC was then poured into a preheated die designed according to the specifications of the work piece. The cast component was machined by using WC insert. The quality of the cast AlSiCp was tested by radiography for discontinuities. An analysis of mechanical properties and Microstructure was carried out to find the effect of dispersion strengthening. The assessed properties were found to be superior when compared with the parent Al 6063 alloy.
