Mpweya wa carbon ndi gulu la zitsulo zokhala ndi carbon monga chinthu chachikulu cha alloying ndi pang'ono za mankhwala ena. Malinga ndi zomwe zili mu kaboni, zitsulo zotayidwa za carbon zingagawidwe kukhala zitsulo zochepa za carbon, medium carbon cast iron ndi carbon cast zitsulo. The carbon zili otsika mpweya kuponyedwa zitsulo ndi zosakwana 0,25%, pamene zili mpweya wa sing'anga kuponyedwa mpweya zitsulo ndi pakati pa 0.25% ndi 0.60%, ndi zili carbon zili mkulu mpweya kuponyedwa zitsulo ndi pakati pa 0,60% ndi 3.0%. Mphamvu ndi kuuma kwa chitsulo cha kaboni kumawonjezeka ndi kuchuluka kwa mpweya wa carbon.Chitsulo cha Cast carbon chili ndi izi: mtengo wotsika mtengo, mphamvu zambiri, kulimba bwino komanso pulasitiki wapamwamba. Chitsulo cha kaboni chotayira chitha kugwiritsidwa ntchito kupanga zida zonyamula katundu wolemetsa, monga zitsulo zogudubuza mphero ndi ma hydraulic press bases mumakina olemera. Itha kugwiritsidwanso ntchito kupanga magawo omwe amakhudzidwa ndi mphamvu zazikulu komanso mphamvu, monga mawilo, ma couplers, ma bolster ndi mafelemu am'mbali pamagalimoto apanjanji.
