Insimbi empunga, noma insimbi empunga, iwuhlobo lwensimbi ekhonjiwe ene-graphite microstructure. Iqanjwe ngombala ompunga we-fracture eyakhayo. Insimbi empunga isetshenziselwa isikoizinsimbi ezimpungalapho ukuqina kwengxenye kubaluleke kakhulu kunamandla ayo aqinile, njengamabhulokhi amasilinda enjini evuthayo, izindlu zephampu, imizimba yamavalvu, amabhokisi kagesi, izisindo zokubala nezinsimbi zokuhlobisa. I-Gray cast iron's high thermal conductivity kanye nomthamo wekhanda othize kuvame ukusetshenziselwa ukwenza i-cast iron cookware nama-disc brake rotor. I-Grey cast iron (ebuye ibizwe ngokuthi i-grey cast iron) iyiqembu lensimbi ekhonjiwe ehlanganisa izinhlobo eziningana zebanga ngokwegama elihlukile lamazinga ahlukahlukene. I-Grey cast iron iwuhlobo lwe-iron-carbon alloy futhi ithola igama layo "grey" ngenxa yokuthi izigaba zabo zokusika zibukeka zimpunga. Isakhiwo se-metallographic se-grey cast iron ikakhulukazi sakhiwe nge-flake graphite, i-metal matrix kanye ne-eutectic yomngcele wokusanhlamvu. Ngesikhathi sensimbi empunga, iCarbon ikwi-flake graphite. Njengenye yezinsimbi zokuphonswa ezisetshenziswa kakhulu, insimbi empunga inezibuyekezo eziningi ezindlekweni, ekulahlekeni nasekusebenziseni imishini.
