Bima ya alloy yina bo ke sadilaka mingi na kibende ya gris .

Ba bima ya alloy yina bo me yika na kibende ya gris ya bo me sala lenda kabwana na kiteso ya fioti na ba ndonga iya, disongidila bima ya graphitisation, bima ya carburisant, bima ya ke simbaka bima mpi bima ya bo me yidika mbote.
Na nzila ya kukumisa ngolo ya kibende, ya carbone, ya silicium, ya aluminium, ya sulfure, ya cuivre mpe ya nikele kele na kisalu ya kupesa maboko na kusalama ya graphite, yina lenda bakama bonso bima ya graphite. Kansi, e nluta mia lekwa yaswaswana kikilu, nze, e nsongo mia cuivre mia 20% mia silicone. Nickel na kwivre kele mpe na bisalu zole: kupesa maboko na graphitisation na ntangu ya kubaluka ya cocrystal; kukanga graphitisation na ntangu ya transition cocrystal, yina ke sadisaka na kusala ba nsinga ya kuluta mbote, na mpila nde yau lenda mpe kutadila yau bonso kima ya kukangama.
E nluta mia titanium mpe miampasi. Na kutuba ya mbote, titanium kele kima ya ngolo ya ke salaka carbure, kansi ntangu mambu na yo kele fioti kibeni (mu mbandu, .<0.08%), its fine compounds can be used as the core of graphite, has the role of promoting graphitization.
Etani, antimonie, manganese, molybdène, chrome, kivumu ti nioobium yonso lenda kanga yonso nzila ya mvula mpi ya kuyela ya graphite, kutomisa kikalulu ya kusala carburn, mpi yonso kele ya bima ya ke zingaka mbote ya carburn. E nluta mia molibdène mina ye ngwizani ye ntalu andi ya yika. Molybdène na kati ya kibende ya bo me tula na kibende, .<0.8%, the effect of molybdenum is mild, which is to make the pearlite refinement, the content is the carburization stable element. It is generally believed that the role of manganese is to increase the amount of cast iron beads and improve the strength of cast iron. In fact, manganese is also multifaceted, when the content is high, it will make the graphite thick, thus reducing the strength of cast iron.
