Ihe nkedo Shell Iron Ductile

Ngwongwo ductile na-ewu ewu ma nabata ya site na usoro nkedo ịkpụzi shei. Ngwongwo nkedo na-enweta graphite nodular site na usoro nke spheroidization na ọgwụgwọ inoculation, nke na-eme ka ihe ndị na-emepụta ihe na-arụ ọrụ nke ọma, karịsịa plasticity na ike siri ike, iji nweta ike dị elu karịa carbon ígwè. Ihe nkedo ductile bụ ihe nkedo nke nwere ike dị elu na njirimara ya zuru oke dị nso na ígwè. Dabere na njirimara ya magburu onwe ya, a na-eji ígwè ductile eme ihe nke ọma maka ịkwanye akụkụ nke ike mgbagwoju anya, ike, ike siri ike na mgbochi iyi. A na-ejikarị ígwè eme ihe na-emepụta akụkụ maka crankshafts na camshafts maka ụgbọ ala, traktọ, na engine combustion n'ime, yana valves nrụgide maka igwe n'ozuzu.
