I-Nodulizer yinto ekhobokisayo enokukhuthaza ukwenziwa kwe-spheroidal graphite ukusuka kwiziqwenga zegraphite kwiinkqubo zemveliso.Iyakwazi ukukhuthaza iigrafu ze-spheroidal kunye nokwandisa inani leegrafu ze-spheroidal ukwenzela ukuba iimpawu zabo zomatshini ziphuculwe.Ngenxa yoko, i-ductility kunye nobunzima
