Grey iron, kana grey cast iron, imhando yesimbi yakakandwa ine graphite microstructure. Inotumidzwa zita regrey ruvara rwekutsemuka kwainoumba. Iyo grey cast iron inoshandiswa kune tsikagrey iron castingsuko kuomarara kwechikamu kunonyanya kukosha kupfuura simba rayo rekusimba, senge mukati memoto injini cylinder blocks, pombi housings, miviri yevharuvhu, mabhokisi emagetsi, counterweights uye majekiseni ekushongedza. Grey cast iron's high thermal conductivity uye chaiyo musoro kugona kunowanzo shandiswa kugadzira cast iron cookware uye disc brake rotors. Grey cast iron (inonziwo grey cast iron) iboka resimbi yakakandwa inosanganisira akati wandei marudzi egiredhi zvinoenderana nemazita akasiyana ezviyero zvakasiyana. Grey cast iron imhando yesimbi-kabhoni alloy uye inowana zita rayo "grey" kubva mukuti zvikamu zvavo zvekucheka zvinotaridzika grey. Iyo metallographic chimiro chegrey cast iron inonyanya kuumbwa neflake graphite, simbi matrix uye zviyo muganho eutectic. Munguva yesimbi yegrey, Carbon iri muflake graphite. Seimwe yeanoshandiswa zvakanyanya kukanda simbi, grey iron ine akawanda advangates mumitengo, castability uye machinablity.
