Isishwankathelo semibhobho yentsimbi yentsimbi
Ingaphezulu kweminyaka engama-70 ukusukela oko kufakwe umbhobho wentsimbi ye-ductile nge-1940s. Ngamandla ayo aphezulu, i-elongwation ephezulu, ukuxhathisa okuphezulu, ukwakha kothukile, ukwakha ngokulula kunye nezinye iimpawu ezintle, umbhobho wentsimbi yentsimbi lolona hambo ludlulayo kwigesi kunye negesi ngokukhuselekileyo. I-ductile yentsimbi, ebizwa ngokuba yintsimbi yentsimbi okanye i-spheroalal i-iron, iphawulwa bubukho begrafiki ye-spheroid kwiziphumo.

Oonobumba bemibhobho yentsimbi yentsimbi
Imibhobho yentsimbi ye-ductile ifumaneka kuluhlu lweedayimitha ukusuka kwi-80 mm ukuya kwi-2000 mm kwaye zilungele ukuhanjiswa kwamanzi okubi nokusasazwa (ngokungqinelana ne-BS En 598). Imibhobho yentsimbi yentsimbi ilula ukuyidibanisa, inokubekwa kuzo zonke iimeko zemozulu kwaye ihlala ingenamsebenzi wokubuyela umva okhethiweyo. Eyona nto iphambili kukhuseleko kunye nokukwazi ukuhlalisa intshukumo yomhlaba kuyenza ibe yeyona nto ifanelekileyo yemibhobho yoluhlu olubanzi lwezicelo.
Amabakala ombhobho wentsimbi yentsimbi sinokubonelela
Le theyibhile ilandelayo ibonisa onke amabakala e-ructile yentsimbi yelizwe ngalinye.IU-Merika, emva koko unokukhetha i-60-40-18, 65- 40-12, 70-50.

Izicelo zentsimbi ye-ductile
Intsimbi ye-ductile inamandla amakhulu kunye ne-tycity kunentsimbi engwevu. Ezo ndawo ziyivumela ukuba isetyenziswe kakuhle kwizicelo ezahlukeneyo zeshishini, kubandakanya izinto eziqhutywa ziivili, amavili, iibhokisi zegiya, iiplanga zamakhaya, kunye nezinye ezininzi. Kuba ayiphumanga njenge-Iron yentsimbi, i-ductile yentsimbi ikhuselekile ukuyisebenzisa kwizicelo zokukhusela iimpembelelo, ezinjengeBlallards.
