Wesi tuang minangka paduan wesi-karbon kanthi fraksi massa karbon luwih saka 2,11%. Wesi tuang dipikolehi kanthi remelting wesi babi ing tungku, nambah ferroalloy, baja kethokan, lan bali menyang tungku kanggo nyetel komposisi.wesi abu-abulan wesi ductile minangka rong wesi sing paling akeh digunakake kanggo ngasilake casting.
Gelar wesi tuang China utamane dituduhake lan dibedakake kanthi sifat mekanik. Setel nomer pisanan ing kelas nuduhake kekuatan tarik minimal (ing MPa), lan nomer nomer loro (yen ana) nuduhake elongasi minimal nalika istirahat (%). Rong set nomer kasebut dipisahake kanthi garis "-".
Kode huruf Inggris saka wesi tuang abu-abu yaiku HT, ing ngendi H minangka huruf pisanan saka Pinyin Cina (Hui Se) sing tegese abu-abu; T minangka huruf pisanan saka Pinyin Cina (Tie) saka wesi. Angka ing kelas wesi abu-abu China nuduhake kekuatan tarik minimal (MPa). Contone, HT250 nggambarake wesi tuang abu-abu kanthi kekuatan tarik minimal 250 MPa.
