Cast iron - Wikipedia

Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the

Plain graphite has only delocalized electrons due to the sp 2 hybridized carbon atoms. In comparison, KC 8 has a higher electrical conductivity thanks to its rapid electron exchange. Therefore, additional delocalized electrons wander across the graphite layers while electrons available for donation are accessible on the surface.
