Ib qho tshwj xeeb ntawm grey cam khwb cia hlau castings yog kev faib tawm ntawm graphite hauv daim ntawv ntawm flakes; cov flakes no ua rau "thaum" cov hlau matrix, ua rau cov khoom muaj kev ntxhov siab ntawm cov lus qhia graphite thaum raug loads. Yog li ntawd, thaum grey cam khwb cia hlau muaj lub zog compressive siab, nws lub zog tensile thiab toughness kuj tsis tshua muaj, ua rau nws zoo dua haum rau cov ntaub ntawv uas muaj compressive loads.
Grey cam khwb cia hlau castings nthuav tawm kev co zoo heev -damping thiab hnav- cov khoom tiv taus. Cov qauv flake graphite absorbs vibrational zog, ua rau kev siv dav hauv cov khoom xws li cov cuab yeej siv lub txaj thiab cav lub tog raj kheej thaiv qhov twg qhov kev vibration yog qhov tseem ceeb. Tsis tas li ntawd, cov khoom muaj cov yam ntxwv zoo sib xws, ua tau zoo nyob rau hauv qhov chaw sib txuas uas tsis tas yuav muaj kev cuam tshuam loj heev.
Grey cam khwb cia hlau kuj boasts zoo heev casting yam ntxwv, nrog rau ib tug kuj tsis tshua muaj melting kub, zoo fluidity, thiab tsawg shrinkage, uas pab txhawb kev tsim ntawm complex structural qhov chaw. Cov cwj pwm no muab tus nqi kom zoo dua hauv kev tsim cov khoom loj ntawm kev sib tw castings thaum tib lub sij hawm txo qhov kev pheej hmoo ntawm qhov tsis xws luag.
Grey cam khwb cia hlau castings muab zoo machinability; chips tawg yooj yim thaum txiav, machining efficiency siab, thiab cov cuab yeej hnav kuj tsawg. Txawm li cas los xij, txij li nws cov khoom siv kho tshuab tau cuam tshuam los ntawm matrix microstructure (xws li qhov piv ntawm pearlite rau ferrite), cov txheej txheem ntau lawm feem ntau koom nrog kev tswj cov tshuaj muaj pes tsawg leeg thiab kho cov nqi cua txias kom ua tau zoo kawg nkaus.
