In the present study, aimed to find out the dielectric property of LM25 alloy dispersed with SiC particles by Stir casting technique. Stir casting was carried out with a continuous stirring by melting LM25 alloy and subsequent adding of SiC. Following Stir casting, a detailed microstructural and phase analysis of the composite were carried out. The hardness of the composite was measured and dielectric property was evaluated in details. Rockwell hardness of the composite was significantly improved to as high as 85 (B-Scale) as compared to 35 (B-Scale) of the as received LM25 alloy. The dielectric property of the composite samples was negative as compared to the as-received specimen.
