China OEM isiko ductile castings yentsimbi ngeinkqubo yokuphosa utyalo-mali olulahlekileyo. Intsimbi yentsimbi, ekwabizwa ngokuba yi-ducitle cast iron, nodular iron, spheroidal graphite iron, spheroidal graphite cast iron, okanye nje intsimbi yeSG ngokufutshane.Xa i-graphite ikhona njengamancinci amancinci, ajikelezayo, kwaye asasazwe kakuhle, umphumo wayo obuthathaka uncinci kwaye iintsimbi ezinjalo eziphosiweyo ziya kuba ne-ductility ephezulu. Olu hlobo lwentsimbi lubizwa ngokuba yi-ductile okanye i-nodular iron okanye i-spheroidal graphite okanye ngokulula i-SG iron. Olu hlobo lwegraphite lunokufezekiswa ngokudibanisa i-elemental magnesium okanye i-cerium okanye indibaniselwano yezinto ezimbini kwintsimbi etyhidiweyo. I-Magnesium yongezwa kubuninzi be-0.07 ukuya kwi-0. 10% ilandelwa ngokongezwa kwe-ferro-silicon ukukhuthaza i-graphitization. Ngexesha lokuqina, i-magnesium inceda ekusasazeni igraphite kuyo yonke isinyithi.
I-Ductile iron inomlinganiselo ongcono wokomelela ukuya kubunzima, ukunyanzeliswa okungcono kunye nexabiso lempembelelo ephezulu. Ngaphezulu, amacandelo entsimbi adityanisiweyo aveliswa ngenkqubo yokuphosa apho ulawulo olungcono lwemilo yecandelo lunokufezekiswa xa kuthelekiswa nokuwisa. Yiyo loo nto, uninzi lwamalungu anje nge crank shafts kunye nee rods ezidityanisiweyo ezenziwe ngokuqhelekileyo ngokufakwa kwedropha ziya zithathelwa indawo yi ductile iron castings.
