Graphite ufa ndi mtundu wa gwero la mchereufandi zolemba zofunika. Chigawo chake chachikulu ndi carbon yosavuta, yomwe imakhala yofewa, yakuda imvi komanso yamafuta. Kulimba kwake ndi 1 ~ 2, ndipo kumawonjezeka kufika ku 3 ~ 5 ndi kuwonjezeka kwa zonyansa kumalo ozungulira, ndipo mphamvu yake yokoka ndi 1.9 ~ 2.3 Pansi pa chikhalidwe cha kudzipatula kwa mpweya ndi mpweya, malo ake osungunuka ali pamwamba pa 3000 ℃, yomwe ndi imodzi mwazinthu zamchere zosagwira kutentha.
Pa kutentha kwa firiji, njira yowunikira chidziwitso chamankhwala, kapangidwe kake ndi katundu wagraphite ufandi mwadongosolo ndi khola, ndipo ndi osasungunuka m'madzi, kuchepetsa asidi, kuchepetsa alkali ndi zosungunulira organic. Ntchito yofufuza ya sayansi yazinthu imakhala ndi magwiridwe antchito ena achitetezo chamtundu wapamwamba kwambiri wosagwirizana ndi makina opangira ma conductive, omwe angagwiritsidwe ntchito ngati zida zazikulu zamapangidwe osagwira moto, zida zogwirira ntchito komanso zida zaukadaulo zamafuta.
Pa kutentha kosiyanasiyana, imakhudzidwa ndi mpweya kuti ipangekabonicarbon dioxide kapena carbon monoxide. Pakati pa kaboni, fluorine yokha imatha kuchitapo kanthu mwachindunji ndi elemental carbon. Ukatenthedwa, ufa wa graphite umakokedwa mosavuta ndi asidi. Kutentha kwambiri, ufa wa graphite umatha kuchitapo kanthu ndi zitsulo zambiri kupanga carbides zitsulo, ndipo zitsulo zimatha kusungunuka kutentha kwakukulu.
Graphite ufa ndi tcheru kwambiri mankhwala anachita zakuthupi, ndipo kukana kwake kudzasintha pazikhalidwe zosiyanasiyana.Graphite ufandi zabwino kwambiri zopanda zitsulo conductive zakuthupi. Malingana ngati ufa wa graphite umasungidwa mu zipangizo zotetezera, udzaperekedwa ngati waya wochepa thupi, koma mtengo wotsutsa si nambala yolondola. Chifukwa makulidwe a ufa wa graphite ndi wosiyana, kukana kwa ufa wa graphite kumasiyananso ndi kusiyana kwa zida ndi chilengedwe.
