● Mmanya ujo.Mmụba ujo nke ígwè ductile dị mma karịa nke nkedo isi awọ.Ka ọ̀tụ̀tụ̀ spheroidization dị elu, otú ahụ ka mmịpụta ujo na-adị ntakịrị.Ka okpomọkụ na-arị elu, mwepu ujo nke nkedo isi awọ na-ebelata, mana mmetụta dị na ígwè ductile dị ntakịrị.
● ịcha arụmọrụ.Iron ductile nwere ọtụtụ graphite, nke na-ekere òkè n'ịbelata mmanu mmanu.Ya mere, nkwụsị nkwụsị nke ígwè ductile dị ala karịa nke ígwè, na ịcha ọsọ dị elu.
● Ịdị mma.Enweghị ike ịgbado ígwè ductile, naanị site na ịgbado ọkụ na-arụzi ya.Mgbe ọdịnaya nke magnesium alloy na-adịghị ahụkebe na ígwè ductile dị elu, ọ dị mfe ịmepụta ọnụ ọcha ma ọ bụ nhazi martensitic iji mepụta nrụgide dị n'ime na mgbawa na mpaghara dị nso na weld.
● Nguzogide okpomọkụ.Grafite dị na ígwè ductile na-ekewapụ onwe ya, nke na-egbochi mgbasa nke oxygen na okpomọkụ dị elu ma e jiri ya tụnyere ígwè nkedo isi awọ.Ya mere, nguzogide oxidation na nguzogide uto nke ígwè ductile dị mma karịa nke nkedo isi awọ na ígwè na-adịghị mma.Nguzogide oke okpomọkụ nke ígwè ferritic ductile dị mma karịa nke pearlitic ductile iron.Ịba ụba ọdịnaya nke silicon ma ọ bụ aluminom nwere ike imeziwanye nguzogide oxidation na nguzogide okpomọkụ nke ígwè ductile.
● Nguzogide corrosion.Ígwè úkwù na nke nkedo isi awọ nwere ezigbo nguzogide corrosion na ngwọta alkaline, na nguzogide corrosion nke ígwè ductile na organics, sulfides, na ọla a wụrụ awụ (ebe mgbaze dị ala) yiri nke ígwè nkedo isi awọ.
● Nguzogide abrasion.Ígwè Ductile bụ ihe dị mma na-eguzogide ma na-ebelata iyi, na nkwụsị ya dị mma karịa nke nkedo isi awọ, carbon ígwè na ọbụna obere alloy ígwè nwere otu matrix.
● (1) mmanu mmanu na iyi nguzogide, nguzogide iyi nke ígwè ductile dị mma karịa nke nkedo isi awọ.
● (2) Ọkpụkpụ abrasive, iron ductile nwekwara ngwa ụfọdụ n'okpuru ọnọdụ akwa abrasive.Otú ọ dị, e jiri ya tụnyere ígwè nkedo na-acha ọcha na ígwè alloy dị ala, nkwụsị nke ígwè ductile nkịtị adịghị mma, ọ bụ naanị alloy ductile iron ma ọ bụ alloy Bainite ductile iron nwere ezigbo nguzogide.
