Intsimbi ethambileyo ifanelekile kwizixhobo zevalvu, kuba ineempawu ezininzi. Njengendawo yentsimbi, intsimbi ethambileyo yaphuhliswa ngo-1949. Umxholo wekhabhoni wentsimbi ethambileyo ungaphantsi kwe-0.3%, ngelixa owentsimbi ethambileyo kunye nentsimbi ethambileyo ubuncinci yi-3%. Umxholo wekhabhoni ophantsi wentsimbi ethambileyo wenza ikhabhoni ekhoyo njengegrafiti ekhululekileyo ingabi ziiflakes. Uhlobo lwendalo lwekhabhoni kwintsimbi ethambileyo ziiflakes zegrafiti ezikhululekileyo. Kwintsimbi ethambileyo, igrafiti ikwimo yeeqhuqhuva kunokuba ibe ziiflakes njengakwintsimbi ethambileyo. Xa kuthelekiswa nentsimbi ethambileyo kunye nentsimbi ethambileyo, intsimbi ethambileyo ineempawu zomzimba ezingcono. Ziiqhuqhuva ezijikelezileyo ezithintela ukwenziwa kweentanda, ngaloo ndlela zibonelela nge-ductility ephuculweyo enika i-alloy igama layo. Nangona kunjalo, i-flake kwintsimbi ethambileyo ikhokelela ekunqongophaleni kwe-ductility yentsimbi. Uductility olungileyo unokufumaneka nge-ferrite matrix.

Xa kuthelekiswa nentsimbi ephosiweyo, intsimbi ephosiweyo ineengenelo ezipheleleyo ngamandla. Amandla okutsalwa kwentsimbi ephosiweyo yi-60k, ngelixa lawo entsimbi ephosiweyo yi-31k kuphela. Amandla okuvelisa intsimbi ephosiweyo yi-40k, kodwa intsimbi ephosiweyo ayibonisi amandla okuvelisa kwaye ekugqibeleni iya kuqhekeka.

Amandla entsimbi ethambileyo ayafana nalawo entsimbi ephothiweyo. Intsimbi ephothiweyo inamandla aphezulu emveliso. Amandla aphantsi emveliso yentsimbi ephothiweyo yi-40k, ngelixa amandla emveliso yentsimbi ephothiweyo yi-36k kuphela. Kwiinkqubo ezininzi zikamasipala, ezinje ngamanzi, amanzi anetyuwa, umphunga, ukumelana nokugqwala kunye nokumelana ne-oxidation yentsimbi ephothiweyo zingcono kunezo zentsimbi ephothiweyo. Intsimbi ephothiweyo ikwaziwa njengentsimbi ye-spheroidal graphite. Ngenxa yesakhiwo se-spheroidal graphite, intsimbi ephothiweyo ingcono kunentsimbi ephothiweyo ekutshiseni i-damping, ngoko ke iluncedo ngakumbi ekunciphiseni uxinzelelo. Isizathu esibalulekileyo sokukhetha intsimbi ephothiweyo njengesixhobo sevalvu kukuba inexabiso eliphantsi kunentsimbi ephothiweyo. Ixabiso eliphantsi lentsimbi ephothiweyo lenza le nto ithandwe ngakumbi. Ngaphandle koko, ukukhetha intsimbi ephothiweyo kunokunciphisa iindleko zomatshini.
