Kua roa te mōhiotia o te karāneti hei rauemi matua mō ngā turanga miihini nā ōna āhuatanga tino pai, tae atu ki te matotoru, te pakari, me te ātete ki te horapa wera. He mea nui te mārama ki ngā tawhā hangarau me ngā paerewa e pā ana ki ngā turanga miihini karāneti mō ngā miihini me ngā kaihanga e whakawhirinaki ana ki te tika me te roa o ā rātou mahi.
Ko tētahi o ngā tawhā hangarau matua o ngā turanga miihini karāhe ko tōna kaha pēhi, e ahu mai ana i te 100 ki te 300 MPa. Mā tēnei kaha pēhi teitei ka taea e te karāhe te tu atu i ngā kawenga nui me te kore e rerekē te āhua, he mea tino pai mō te tautoko i ngā mīhini me ngā taputapu taumaha. Hei tāpiri, he iti ngā tauwehenga whānui wera o te karāhe, i te nuinga o te wā tata ki te 5 ki te 7 x 10^-6 /°C, e whakaiti ana i ngā huringa āhua nā te piki me te heke o te pāmahana, e whakarite ana i te mahi pumau i roto i ngā taiao rerekē.
Ko te papatahi o te mata tētahi atu paerewa matua mō ngā turanga miihini o te karāhe. He maha ngā wā ka tohua te ātete papatahi ki roto i ngā maikiromita, ā, mō ngā tono tino tika e hiahia ana kia rite ki te 0.005 mm te ātete mō ia mita. He mea nui tēnei taumata o te tika mō ngā tono pēnei i ngā mīhini ine taunga (CMM) me ngā taputapu whatu, ahakoa he iti noa te pekanga ka arahi pea ki ngā hapa ine nui.
Heoi anō, ko te matotoru o te karāhe kei waenga i te 2.63 ki te 2.75 g/cm³, e whai wāhi ana ki tōna pumau me ōna āhuatanga ārai wiri. He mea nui ēnei āhuatanga hei whakaiti i te pānga o ngā wiri o waho, ā, ka whakarei ake i te tika o ngā taputapu tairongo e mau ana ki ngā turanga karāhe.
Hei whakamutunga, he mea nui ngā tawhā hangarau me ngā paerewa o ngā turanga miihini karāhe i roto i tā rātou whakamahinga puta noa i ngā momo ahumahi. Mā te piri ki ēnei whakaritenga, ka taea e ngā kaihanga te whakarite i te pono me te mahi a ā rātou taputapu, ā, ka mutu, ka pai ake te whai huatanga o te mahi me te tika o ngā tukanga hanga. I te whanaketanga o te hangarau, ka piki haere tonu te hiahia mō ngā turanga miihini karāhe kounga teitei, e whakaatu ana i te hiranga o te mārama ki ēnei paerewa hangarau.
