Cast iron isimbi-carbon alloy ine chikamu chekabhoni yakakura kupfuura 2.11%. Simbi yakakandwa inowanikwa nekunyungudutsa simbi yenguruve muchoto, ichiwedzera ferroalloy, simbi yakaraswa, uye kudzokera kuchoto kunogadzirisa kuumbwa.Gray cast ironuye ductile iron ndiwo maviri anonyanyo shandiswa simbi dzakakandwa pakugadzira ma castings.
China's cast iron iron mamakisi anonyanya kuratidzwa uye anosiyaniswa nemakanika zvivakwa. Seti yekutanga yenhamba mugiredhi inoratidza hudiki hwekusimba simba (muMPa), uye yechipiri seti yenhamba (kana iripo) inoratidza hudiki hurefu panguva yekuzorora (%). Maseti maviri enhamba anoparadzaniswa nedash "-".
Mabhii echirungu kodhi yegrey cast iron iHT, apo H iri vara rekutanga reChinese Pinyin (Hui Se) rinoreva grey; T ndiyo tsamba yekutanga yeChinese Pinyin (Tie) yesimbi. Nhamba dzemagiredhi esimbi ekuChina dzinoratidza hushoma hwekusimba (MPa). Semuyenzaniso, HT250 inomiririra grey cast iron ine simba shoma re250 MPa.
