I-cast iron ingxubevange ye-iron-carbon enengxenye enkulu yekhabhoni engaphezu kuka-2.11%. I-cast iron itholwa ngokuncibilikisa insimbi yengulube esithandweni, ukwengeza i-ferroalloy, insimbi ye-scrap, nokubuyela esithandweni ukuze kulungiswe ukwakheka.Insimbi empungafuthi i-ductile iron yizinsimbi ezimbili ezisetshenziswa kakhulu ezisansimbi zokukhiqiza izinsimbi.
Amamaki e-iron cast aseShayina avezwa kakhulu futhi ahlukaniswa ngezakhiwo zemishini. Isethi yokuqala yezinombolo ebangeni ikhombisa ubuncane bamandla okunyakazisa (ku-MPa), kanti isethi yesibili yezinombolo (uma ikhona) ikhombisa ubude obuncane ngesikhathi sekhefu (%). Amasethi amabili ezinombolo ahlukaniswa ngodwi "-".
Ikhodi yesiNgisi enohlamvu lwensimbi empunga ithi HT, lapho u-H kuwuhlamvu lokuqala lwe-Chinese Pinyin (Hui Se) okusho okumpunga; T wuhlamvu lokuqala lwe-Chinese Pinyin (Tie) yensimbi. Izinombolo ezikumabanga ensimbi empunga yaseShayina zibonisa amandla amancane okudonsa (MPa). Isibonelo, i-HT250 imele insimbi empunga enamandla aqinile angama-250 MPa.

Kunamasethi amabili ezinombolo emabangeni e-iron ductile yaseChina. Isethi yokuqala yezinombolo imele ubuncane bamandla obuncane obungashuki (MPa), kanti isethi yesibili yezinombolo imele ubude ngemva kokuphuka (%). Amasethi amabili ezinombolo ahlukaniswa ngodwi "-". Isibonelo, i-QT400-18 imele insimbi ye-ductile enamandla amancane angama-480 MPa kanye nobude obuncane obungu-18%.
