Hei momo rauemi ātete-kakahu mahi-teitei, kua whānuitia te whakamahinga o ngā ngongo uku alumina i roto i ngā mara ahumahi maha. Ko tōna ātete-kakahu pai rawa atu nā tōna rauemi alumina parakore teitei me te tukanga hanga motuhake. Anei tētahi tātaritanga taipitopito o te ātete-kakahu o ngā ngongo uku alumina.
Ko te wāhanga matua ongā ngongo uku aluminahe alumina, he nui ake i te 90% te parakore. Mā te alumina parakore teitei ka tino pai ngā āhuatanga ā-tinana me te matū o ngā rauemi uku, inā koa te ātete ki te kakahu. E ai ki te whakataunga, ko te ātete kakahu o ngā uku alumina parakore teitei he rite ki te 266 ngā wā o te maitai manganese me te 171.5 ngā wā o te rino maka chromium teitei. Ko te tikanga tēnei i raro i ngā āhuatanga mahi ōrite, mā te whakamahi i ngā wāhanga ātete kakahu uku alumina parakore teitei ka taea te whakaroa ake i te roa o te mahi a ngā taputapu, kia tekau ngā wā pea te roa ake.
He tino teitei te pakeke o ngā ngongo uku alumina, tuarua i te taimana anake, he nui ake i ngā rauemi whakarewa tuku iho pērā i te maitai ātete-kakahu me te maitai kore waikura. Nā te pakeke teitei o ngā ngongo uku alumina he tino pai ki te ātete ki te kakahu me ngā karawarawa. Ina haria ngā rauemi he kaha te whakakōkī i roto i te paipa, pērā i te pungarehu, te waro kua pakaru, te paura kohuke pai, ngā paru, te sima, me ētahi atu, ka taea e te pakeke teitei o te paipa uku alumina te ātete ki te kakahu o ēnei rauemi, ā, ka roa ake te ora o te paipa.
He rauemi uku te ngongo uku alumina i hangaia mā te tukanga pēhi motuhake-isostatic. Mā tēnei tukanga ka ōrite te hanganga karaihe uku, ā, ka whakapai ake i tōna ātete ki te kakahu. I taua wā anō, ka hangaia te ngongo uku alumina hei katoa, ā, kāore e taea te uru te paru, ka whakarei ake hoki i tōna kaha ki te ātete ki te kakahu. E whakaatu ana te whakamātautau ka taea te whakanui ake i te roa o te ora o te ngongo uku alumina he rite te matotoru ki te rima ngā wā ki te whakataurite ki te pepa uku.
Nā te ātete ki te kakahu o te ngongo uku alumina, ka whānuitia te whakamahinga i roto i ngā mara ahumahi maha. Hei tauira, i roto i ngā paipa mira waro me ngā paipa tukunga pungarehu o ngā tipu hiko waro, ka taea e ngā ngongo uku alumina te ātete pai ki te kakahu o te paura waro me te pungarehu, ā, ka roa ake te roa o te mahi a ngā taputapu. Hei tāpiri, he pai hoki te mahi a ngā ngongo uku alumina i roto i ngā maina, i ngā tipu sima me ētahi atu wā e hiahiatia ana te kawe i ngā rauemi huri.
Ki te whakatauritea ki ngā rauemi ātete-kakahu tuku iho, he pai ake te ātete-kakahu o ngā ngongo uku alumina. Hei tauira, ki te whakatauritea ki te maitai ātete-kakahu me te maitai kore waikura, he nui ake te pakeke me te ātete-kakahu o ngā ngongo uku alumina. Ki te whakatauritea ki te paipa kōhatu whakarewa, he iti te mātotoru me te mama o te paipa uku alumina, ā, he watea mō te tāutanga, te kawe me te tiaki. Nā ēnei painga ka waiho ngā ngongo uku alumina hei rauemi ātete-kakahu pai rawa atu i roto i ngā mara maha.
Hei whakarāpopototanga, kua whānuitia te whakamahinga o ngā ngongo uku alumina i roto i ngā mara ahumahi maha nā te mea he tino parakore ngā rauemi alumina, he tino pakeke ngā āhuatanga, he tino motuhake te tukanga hanga, ā, he tino pai te ātete ki te kakahu. Ehara i te mea ka roa ake te ora o ngā taputapu, engari ka whakapai ake hoki i te whai huatanga o te mahi a ngā taputapu, ā, ka nui hoki ngā painga ōhanga ki te whakaputa ahumahi.
