Abstract : Brass is one of the most important domestic, industrial and ornamental alloys of Cu and Zn. Different compositions of brass ranging from Cu wt% 60 to 80 are used wide over. In present study, brass in four compositions has been prepared by sand casting and optical micrography has been done to compare the effect of composition on microstructure. The superheat temperature has also been varied in two steps viz. 980 oC and 1100oC and the effect on microstructure has been reported.
