Tensile test specimens of flake graphite (FG), compacted/vermicular (VG) and spheroidal graphite (SG) structures at five different cooling rates (RC) have been produced by deliberate techniques. The tensile strength (R m ), elongation percentage (A) and aspect ratio (AR) of the three graphite structures have been studied. The relationship between the aspect ratio range and mechanical properties of grey cast iron, compact graphite as well as spheroidal graphite were investigated. A comparative curve for the three graphite structures has been traced so as to correlate the aspect ratio values and the mechanical properties for each one.
