Ngā Mōhiohio Taketake.

Ko te waea Nickel-Chromium 7030 (70% Ni, 30% Cr) he koranu mahi-teitei e whakamahia whānuitia ana i roto i ngā ahumahi nā ōna āhuatanga pai. Kei raro nei he tirohanga whānui.

• Hanganga Matū: He ōwehenga Ni-Cr tino pakari 70/30 me ngā poke whakahaeretia, e hanga ana i tētahi kiriata whakakore mata pumau.
• Ngā Āhuatanga Tinana: Ātete ki te 1100°C; he pumau te kawe hiko; he iti te kawe wera; he tino pumau ngā āhuatanga i raro i ngā huringa pāmahana.
• Ngā Āhuatanga Mīhini: He kaha kume teitei, he ngāwari te kume/piko/whatu (he ngāwari ki te kume/whakapiko/whatu), ā, he kaha te ātete ki te ngenge.

• Ātete ki te Waikura: Ka ātete ki ngā waikawa, ngā kawakore, ngā tote, me ngā taiao makuku, ka whakaiti i ngā hiahia tiaki.
• Pūmautanga Pāmahana-Teitei: He pai ake te mahi a ngā waea Fe-Cr-Al, e pupuri ana i ngā āhuatanga me te kore e waikura/ngāwari i ngā pāmahana teitei.
• Ngāwari ki te Tukatuka: Ka taea te urutau ki te tuhi (ngā waea tino pai), te raranga (mata), me te piko mō ngā āhua rerekē.
• Te Roa o te Ora: Ka mahi pumau mō ngā mano hāora, ka whakaiti i ngā utu whakahaere.

• Taputapu Whakamahana: Ngā wāhanga whakamahana i roto i ngā ngongo hiko (ngā whakamahana wai, ngā whakamahana ahumahi) me ngā waea/whitiki whakamahana (te whakamarumaru o ngā paipa).
• Hikohiko: Waea ātete mō ngā ātete/pūwerohiko tino tika; rauemi hiko mō ngā takirua/pūoko pāmahana teitei.
• Matū/Pūngao Hinu: Ngā gasket/puna/tātari ātete-waikura; ngā huānga whakamahana i roto i ngā taiao whakaputa waikura.
• Rererangi/Motuka: Ngā wāhanga pāmahana teitei (ngā gaskets miihini) me ngā wāhanga pūnaha hiko (ngā taura waea).
• Hauora: Ngā wāhanga whakamahana i roto i ngā mīhini whakahoromata/whakapūkara; ngā wāhanga tino tika (ngā waea ārahi) i muri i te maimoatanga hototahi koiora.
