Grey iron, kapa grey cast iron, ke mofuta oa tšepe oa tšepe o nang le graphite microstructure.Re bitsa mofuta ona oa tšepe e bohlooho ka lebaka la 'mala o moputsoa oa ho robeha.Bakeng sa graphite e tlotsang sehiloeng le ho pshatla li-chips, tšepe e bohlooho ke motsoako o tloaelehileng oa cast ka lebaka la theko ea eona e batlang e le tlaase le machinability e ntle.Ntle le moo, hobane graphite flakes self lubricate, e boetse e na le galling e ntle le ho se sebetse hantle.
Grey iron e boetse e na le shrinkage e fokolang ea ho tiea ho feta litšepe tse ling ka lebaka la microstructure ea graphite.Ha e ntse e lahla, karolo ea silicon e ka khothaletsa khanyetso e ntle ea kutu le ho eketsa mokelikeli ha o lahla.Ka kakaretso tšepe e putsoa e nkoa e le bonolo ho e cheseletsa.Ha ho bapisoa le tse linglitšepe tsa tšepe, tšepe e bohlooho e na le matla a tlaase a ho tsitsa le ductility;ke ka lebaka leo tšusumetso le ts'oaetso ea ts'oaetso ea mofuta ona oa thepa e batlang e le sieo.
