Wesi abu-abu, utawa wesi tuang abu-abu, minangka jinis wesi tuang sing nduweni struktur mikro grafit. Iki dijenengi sawise werna abu-abu saka fraktur sing dibentuk. Wesi tuang abu-abu digunakake kanggo adatcasting wesi werna abu-abuing ngendi kaku komponen luwih penting tinimbang kekuatan tarik, kayata blok silinder mesin pembakaran internal, omah pompa, awak tutup, kothak listrik, bobot counter lan casting hiasan. Konduktivitas termal dhuwur wesi abu-abu lan kapasitas sirah spesifik asring dimanfaatake kanggo nggawe peralatan masak wesi lan rotor rem cakram. Wesi tuang abu-abu (uga disebut wesi tuang abu-abu) minangka klompok wesi tuang sing kalebu sawetara jinis kelas miturut sebutan sing beda-beda saka standar sing beda-beda. Wesi tuang abu-abu minangka jinis paduan wesi-karbon lan diwenehi jeneng "abu-abu" amarga bagean pemotongan katon abu-abu. Struktur metalografi wesi tuang abu-abu utamane kasusun saka grafit serpihan, matriks logam lan eutektik wates butir. Sajrone wesi abu-abu, Karbon ana ing grafit flake. Minangka salah siji saka logam casting digunakake digunakake, wesi werna abu-abu wis akeh advangates ing biaya, castability lan machinablity.
