Intsimbi engwevu, okanye intsimbi engwevu, luhlobo lwentsimbi etyhidiweyo ene-graphite microstructure. Ithiywe ngombala ongwevu wokuqhekeka owenzayo. Intsimbi engwevu isetyenziselwa isikoiintsimbi ezingwevuapho ukuqina kwecandelo kubaluleke kakhulu kunamandla alo okuqina, njengeebhloko ze-cylinder injini yokutsha yangaphakathi, izindlu zempompo, imizimba yevalvu, iibhokisi zombane, iintsimbi zokubala kunye neecastings zokuhombisa. I-iron ekhutshiweyo ephezulu ye-thermal conductivity kunye nomthamo okhethekileyo wentloko zihlala zisetyenziselwa ukwenza i-cookware yentsimbi kunye ne-disc brake rotors. Intsimbi yentsimbi engwevu (ekwabizwa ngokuba yintsimbi engwevu) liqela lentsimbi etyhidiweyo equka iindidi ezininzi zebakala ngokwemigangatho eyahluka-hlukeneyo. Intsimbi engwevu luhlobo lwe-iron-carbon alloy kwaye ifumana igama layo "grey" kwinto yokuba amacandelo abo okusika abukeka engwevu. Isakhiwo se-metallographic ye-grey cast cast iron ikakhulu yenziwe nge-flake graphite, i-metal matrix kunye ne-gray boundary eutectic. Ngexesha lentsimbi engwevu, iCarbon ikwi-flake graphite. Njengenye yesinyithi esisetyenziswa ngokubanzi, intsimbi engwevu inee-advangates ezininzi kwiindleko, ukuphosa kunye nobuqili.
