Iron nkedo bụ ihe na-eme ka carbon-carbon nwere ihe karịrị 2% carbon. A na-agwakọta ígwè na carbon n'ụdị a chọrọ ma gbazekọ ọnụ tupu a tụba ya n'ụdị.
Ụdị 1-Igwe ntụ ntụ ntụ
Ígwè nkedo isi awọ na-ezo aka n'ụdị ígwè nkedo nke edoziworo iji mepụta mkpụrụ ndụ graphite (carbon) efu n'ime igwe. Enwere ike ịchịkwa nha na nhazi nke graphite site n'ịkwado ọnụego nju oyi nke ígwè na site na ịgbakwunye silicon iji mee ka graphite guzosie ike. Mgbe Iron Cast Grey gbajiri agbaji, ọ na-agbaji n'akụkụ flakes graphite ma nwee ọdịdị isi awọ na saịtị mgbaji ahụ.
Ígwè nkedo isi awọ adịghị ka ductile dị ka ígwè nkedo ndị ọzọ, agbanyeghị, ọ nwere ezigbo ọkụ na-eme ka ọ dị mma na ikike ikpochapụ ígwè niile. Ọ dịkwa ike iyi na-eme ka ọ bụrụ ihe na-ewu ewu iji rụọ ọrụ.

Ụdị 2-Ọcha Nkedo Ígwè
A na-akpọ Iron Cast White aha dabere na ọdịdị nke mgbaji. Site n'ịchịkwa ihe dị n'ime carbon nke ọma, ibelata ọdịnaya silicon, na ịchịkwa ọnụ ọgụgụ dị jụụ nke ígwè, ọ ga-ekwe omume iri carbon niile dị na ígwè n'ime ọgbọ nke ígwè carbide. Nke a na-eme ka o doo anya na enweghi mkpụrụ ndụ graphite n'efu ma mepụta ígwè nke siri ike, nke na-adịghị ike, na-eguzogide oke ike ma nwee nnukwu ike mkpakọ.

A na-eji Iron Cast White eme ihe nke ọma maka ihe ndị na-adịghị eyi ya n'ime ụlọ mgbapụta, igwe igwe na mkpanaka, igwe nhịahụ na akpụkpọ ụkwụ breeki.
Ụdị 3-Ihe nkedo ductile Iron
A na-emepụta Iron Cast Ductile site n'ịgbakwụnye obere magnesium, ihe dịka 0.2%, nke na-eme ka graphite na-eme ka ọ bụrụ ntinye okirikiri nke na-enye ígwè nkedo ductile karịa. Ọ nwekwara ike iguzogide ịgba ígwè dị ọkụ karịa ngwaahịa nkedo ndị ọzọ.
A na-ejikarị Ductile Cast Iron eme ihe maka ductility ya na enwere ike ịhụ ya nke ọma na akụrụngwa mmiri na nsị. Nguzogide ịgba ígwè na-eme ka ọ bụrụ nhọrọ a ma ama maka crankshafts, gia, nkwusioru ọrụ dị arọ na breeki.
