Langai, casting performance gaw kaja ai. Shi gaw kaja ai ntsin rawng ai, n-gun ja ai hkrang daw ni hpe shapraw lu ai, ga shadawn, gray cast iron hte n-gun ja ai cavity structure hte n-gun ja ai cavity structure hte zawn re ai n-gun ja ai hkrang daw ni hpe grau htap htuk ai. Bai nna, shi a shrinkage rate gaw kaji ai, dai gaw shrinkage hka htung ni, n-gun n rawng ai lam ni hte kaga n kaja ai lam ni hpe shayawm ya lu ai.
Lahkawng ngu na gaw, grai kaja ai shock absorption a sutgan re. Dai gaw, grey cast iron hte galaw da ai machine yupku zawn re ai vibration hpe atsawm sha hkap la lu ai, bungli galaw ai lam hta vibration hpe shayawm ya lu ai, dai hku nna, galaw shapraw ai lam a hkrak ai lam hpe grau kaja hkra galaw lu ai.
Masum, n-gun ja ai n-gun hpe ninghkap lu ai. Gray cast iron hta graphite, graphite gaw sau bang ai akyu nga ai, piston ring, brake drum hte kaga daw ni hpe n-gun n rawng ai hpe hkam sharang ra ai.
Mali ngu na hta, cutting hte processing galaw ai lam gaw kaja ai. Graphite nga ai majaw, cutting processing hta grey cast iron byin shangun ai majaw, cutting chip hpe daw kau na matu loi ai, tool a bu hpun ai lam gaw kaji ai majaw, daw amyu myu de galaw na matu loi ai .
