Intsimbi yentsimbi eMalleable
Intsimbi ethambileyo etyhidiweyo yintsimbi egayiweyo emhlophe ekhutshiweyo.Unyango lobushushu be-annealing luguqula ulwakhiwo olune-brittle njengelokuqala ukuphoswa kwifom ethambileyo.Ngoko ke, ukubunjwa kwayo kufana nentsimbi emhlophe, enexabiso elincinci lekhabhoni kunye ne-silicon.Intsimbi ethambileyo iqulathe amaqhuqhuva egraphite angekho ngqukuva ngokwenene njengoko ekwintsimbi edityanisiweyo ngenxa yokuba enziwe kunyango lobushushu kunangexesha lokupholisa ekunyibilikeni.Isinyithi esithambileyo senziwe ngokuphosa kuqala intsimbi emhlophe ukwenzela ukuba i-flakes ye-graphite igwenywe, kwaye yonke i-carbon enganyibilikiyo ikwimo ye-iron carbide.Intsimbi ethambileyo iqala njengokugalelwa kwentsimbi emhlophe ephathwa ubushushu usuku okanye ezimbini malunga ne-950 °C (1,740 °F) emva koko iphole ngosuku okanye ezimbini.Ngenxa yoko, i-carbon kwi-iron carbide iguqula ibe ngamaqhuqhuva egraphite ejikelezwe yi-ferrite okanye i-pearlite matrix, kuxhomekeke kwisantya sokupholisa.Inkqubo ecothayo ivumela ukuxinana komphezulu ukwenza amaqhuqhuva egraphite kunokuba amaflakes.Intsimbi enyibilikayo, njengentsimbi edityanisiweyo, ine-ductility ebonakalayo kunye nokuqina kuba idibanisa i-nodular graphite kunye ne-low carbon metallic matrix.Njengentsimbi ye-ductile, isinyithi esithambileyo sikwabonisa ukuxhathisa okuphezulu kwi-corrosion kunye nokusebenza kakuhle.Umthamo ofanelekileyo wokudambisa wentsimbi kunye namandla okudinwa nawo aluncedo kwinkonzo ende kwiindawo ezinoxinzelelo olukhulu.Zimbini iindidi zentsimbi enyibilikayo ye-ferritic: i-blackheart kunye ne-whiteheart.

Ihlala isetyenziselwa ukuphosa okuncinci okudinga amandla alungileyo kunye nokukwazi ukugoba ngaphandle kokwaphuka (i-ductility).Ukusetyenziswa kweentsimbi ezithambileyo eziphoswayo ziquka iindawo ezininzi zeemoto eziyimfuneko ezifana nabathwali abahlukeneyo, iimeko ezahlukeneyo, iikepusi zokuthwala, kunye nezindlu zezixhobo zokuqhuba.Olunye usetyenziso lubandakanya izixhobo zezandla, izibiyeli, iinxalenye zoomatshini, izixhobo zombane, izixhobo zombhobho, izixhobo zasefama, kunye nezixhobo zemigodi.
