ʻO ka hao hina, a i ʻole ka hao hina hina, he ʻano hao hao i loaʻa kahi microstructure graphite. Kapa ʻia ʻo ia ma muli o ke kala hina o ka haʻihaʻi i hana ʻia. Hoʻohana ʻia ka hao hina hina no ka maʻamauhao hina hinakahi ʻoi aku ka nui o ka ʻoʻoleʻa o ka ʻāpana ma mua o kona ikaika tensile, e like me nā poloka cylinder engine combustion internal, nā hale pahū, nā kino valve, nā pahu uila, nā paona kūʻē a me nā mea hoʻonaninani. Hoʻohana pinepine ʻia ka haʻahaʻa haʻahaʻa haʻahaʻa o ka hao hao hina a me ke poʻo kikoʻī e hana i nā mea kuke hao hao a me nā rotors brake disc. ʻO ka hao hoʻoheheʻe hina (i kapa ʻia hoʻi ka hao hina hina) he pūʻulu hao hoʻoheheʻe ʻia me nā ʻano papa like ʻole e like me ka inoa ʻokoʻa o nā kūlana like ʻole. ʻO ka hao hao hina ke ʻano o ka hao-carbon alloy a loaʻa iā ia kona inoa "hina" ma muli o ke ʻano o ko lākou ʻokiʻoki ʻana i ka hina. ʻO ka hana metallographic o ka hao hina hina ka mea nui i haku ʻia me ka flake graphite, metala matrix a me ka grain boundary eutectic. I ka wā o ka hao hina, aia ka Carbon i ka flake graphite. E like me kekahi o nā metala hoʻoheheʻe nui ʻia, hoʻolei ʻia ka hao hina he nui nā mea kōkua i nā kumukūʻai, castability a me ka machinablity.
