Ho lahla lehlabathee hlahisoang ka tšepe e bohlooho ke motsoako o theko e boima haholo hobane tšepe e bohlooho ha e theko e tlase mme ho lahla lehlabathe ho ka fihlela moralo o tenyetsehang meahong.Tšepe e bohlooho e entsoeng ka tšepe(hape e bitsoa grey cast iron) ke sehlopha sa tšepe e entsoeng ka tšepe e kenyelletsang mefuta e mengata ea maemo ho latela litlhaloso tse fapaneng tsa maemo a fapaneng. Grey cast iron ke mofuta oa tšepe ea carbon alloy 'me e reha lebitso la eona "grey" ka lebaka la hore likarolo tsa tsona tsa ho seha li shebahala li le thokoa. Sebopeho sa metallographic sa tšepe e bohlooho e entsoe haholo ka flake graphite, matrix ea tšepe le eutectic ea moeli oa lijo-thollo. Nakong ea tšepe e bohlooho, Carbon e ka har'a graphite ea flake. Joalo ka e 'ngoe ea litšepe tse sebelisoang haholo, tšepe e bohlooho e na le litlatsetso tse ngata mabapi le litšenyehelo, bokhoni le machinablity.
