Hoolei onei hana ʻia me ka hao hina, he kumu kūʻai maikaʻi loa ia no ka mea ʻoi aku ke kumu kūʻai o ka hao hina a hiki i ka hoʻolei ʻana i ke one ke hiki i ka hoʻolālā maʻalahi i nā hale.hao hina hina(i kapa ʻia hoʻi ka hao hina hina) he pūʻulu hao hoʻoheheʻe me nā ʻano papa like ʻole e like me ke ʻano o nā kūlana like ʻole. ʻO ka hao hao hina ke ʻano o ka hao kalapona a loaʻa 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.
