I roto i te ao tere o ngā rauemi mama, he iti noa ngā tautohetohe e whakaohooho ana i ngā kaihangarau pērā i te konumohe 6061 me te konumohe 7075. Ko ēnei koranu e rua te mea nui rawa atu i ngā pito rerekē o te whānuitanga o te mahi: ko te 6061 te mea pono e kitea ana i roto i ngā mea katoa mai i ngā anga pahikara ki ngā hanganga motuka, ko te 7075 te toa tino kaha e whakakaha ana i ngā parirau rererangi me ngā taputapu hākinakina teitei. I te pikinga ake o te tono konumohe i te tau 2026—nā te mama o te papaaho EV, te horapa o te drone, me te hanganga pumau—mā te whiriwhiri i waenga i ēnei ka taea te whakatau, te whakakore rānei i te utu, te pakari, me te mahi o te hoahoa.
E matapaetia ana ka eke te kai konumohe o te ao ki te 78 miriona tana i tēnei tau, me6xxx me 7xxxngā tohu raupapa e ārahi ana i te utu i roto i ngā tono hanganga. Kei te piki tonu ngā utu mō te 6061 me te 7075, ko te 7075 e utu ana i te 20–40% teitei ake nā te nui o te konutea me te uaua o te tukatuka. Anei tētahi whakamārama mārama mō te āhua o te whakarārangitanga, i runga i ngā āhuatanga o te ao tūturu, ngā tono, ngā kaha, ngā ngoikoretanga, me te wā e tino pai ake ai tetahi i tetahi.
Ngā Āhuatanga Matua i te Tirohanga Poto
6061 (Raupapa 6xxx – Al-Mg-Si, Ka taea te rongoā mā te wera)

Ngā Painga Matua me ngā Huakore
Ngā Kaha 6061:
- He tino pai te whakarewa - he pai mō te MIG/TIG me te iti o te mōrearea pakaru
- He ātete pai ki te waikura – he mea tino pai mō te whakamahi i waho, i te moana rānei
- He tino pai te mīhini me te hanga - he māmā ake te whakaputa, te piko, me te whakakorikori mō ngā whakaotinga
- He ātete pai ki te ngenge, he kaha ngawari hoki, he iti ake te utu
- He whānuitia te wātea i roto i ngā āhua rerekē: he mea whakapūpū, he pepa, he pereti, he ngongo, he pae
Ngā ngoikoretanga 6061:
- Kaha mutunga iti - kāore e pai mō ngā tono kawenga nui
- Ka whakangawari ake i runga ake i te ~200°C, ka whakawhāiti i te whakamahinga i te pāmahana teitei
- He iti ake te pakari o te whati i ētahi atu kaiwhakataetae i roto i ngā wāhanga matotoru
Ngā Kaha 7075:
- He ōwehenga kaha-ki-taumaha tino pai – he rite ki ētahi maitai engari he mama tonu
- He pakari teitei me te ātete ki te kakahu - he tino pai mō te utaina huringa ahotea teitei
- He tino pai te mahi miihini i roto i te pāmahana T6
- Ka mau tonu ngā āhuatanga i ngā pāmahana i raro i te kore (e whakamahia ana i roto i ngā tono cryogenic)
Ngā ngoikoretanga 7075:
- He ngoikore te āheinga whakarewa – he ngāwari ki te pakaru; ko te nuinga o ngā hoahoa ka whakawhirinaki ki te whakapūmau, ki te here rānei
- He tino ngāwari ki te pakaru i te waikura me te kore e tika te maimoatanga wera, te whakakikorua rānei
- He nui ake te utu o ngā rauemi mata me te tukatuka
- He iti ake te ngāwari – ka pakarukaru i te pānga
Ngā Taupānga o te Ao Tūturu: Te Wāhi e Hiranga ai Ia
6061 Te Mana i roto:
- Te anga waka, ngā paepae pākahiko EV, me ngā anga hanganga (he māmā ake ngā hiahia whakarewa)
- Ngā whakatōtōtanga whare, ngā anga matapihi, me ngā tūāpapa
- Ngā wāhanga moana, ngā anga pahikara, me ngā taonga hākinakina
- Ngā totohu wera me te hanganga whānui he mea nui te utu me te waikura
7075 Ka ārahi i roto:
- Ngā wāhanga hanganga ā-rangi (ngā peka parirau, ngā anga o te tinana rererangi)
- Ngā taputapu piki toka mahi-teitei, ngā pū hopu pū, me ngā taputapu rautaki
- Ngā wira hākinakina motuka, ngā wāhanga whakatārewatanga, me ngā ringa o te drone
- Ngā pereti taputapu me ngā pokepoke e hiahia ana kia tino pakari
Hei tauira, i roto i te hoahoa EV, he maha ngā kaihanga e whakakotahi ana i ngā mea e rua: 6061 mō ngā hanganga tinana ka taea te whakarewa me te 7075 mō ngā ara kawenga nui pēnei i ngā maunga whakatārewatanga.
Ngā Whakatairitenga Upoko-ki-Upoko
- Ngā Hiahiatanga KahaKi te hiahia koe ki te kume >500 MPa, ka toa te 7075. Mō te 300–400 MPa, ka tukuna e te 6061 te 80% o te mahi i te 60% o te utu.
- Te Whakapuakitanga o te WaikuraKo te 6061 te kōwhiringa mārama i waho, i roto rānei i ngā taiao makuku. Me whakamahi ngā paparanga Alclad, ngā paninga rānei hei taurite mō te 7075.
- Ngāwari o te HangaHe māmā ake te whakamahi i te 6061 mō te whakarewa me te hanga—he pai mō ngā tauira tauira, mō te hanga rahinga-waenga rānei.
- Taumaha-Hiranga-Teitei-AumahaKo te matotoru o te 7075 ka whakakorengia e ngā wāhanga angiangi ake nā te kaha nui ake.
- Te aro nui ki ngā utuHe pai ake te uara o te 6061 mō te nuinga o ngā tono arumoni; he pai ake te 7075 i roto i te rererangi me te tiaki waka ina kore e taea te rahunga.
Ngā Auahatanga Mākete o te tau 2026 e Āwhina ana i te Kōwhiringa
Kei te whakawhāitihia te rerekētanga utu e te pikinga ake o ngā ihirangi hangarua (inaianei neke atu i te 40% i roto i te maha o ngā mira), ā, kei te whakapai ake ngā whanaketanga hou o te maimoatanga wera i te ātete waikura o te 7075 (tirohia ngā whakamāmā T73/T77 e puta ake ana). I taua wā, kei te whakanui ake ngā momo 6061 me te scandium tāpiri i te kaha mō ngā tono EV. Kei te akiakihia e ngā ture pumau i Ūropi me California te 7075 kua whakakikoruatia me te 6061 kua whakakikoruatia kia roa ake te ora ratonga.
Ko te tino take: Kāore he toa whānui—ko te 6061 te toa o ia rā, ko te 7075 te toa motuhake. Whakatauritehia te koranu ki ō kaupapa matua: ko te tahua me te hanga e pai ake ana ki te 6061; ko te mahi tino pai e pai ake ana ki te 7075.
Mena kei te rapu koe i tētahi kaupapa, tirohia ā mātou rauemi katoarārangi rauemi konumoherāneitukua mai he karere ki a mātou– kei a mātou ēnei momo taonga katoa, ā, ka taea e mātou te āwhina ki ngā mahi a te tari tāke.
(Ngā āhuatanga e hangai ana ki ngā paerewa ASTM me ngā pepa raraunga ahumahi; me manatoko tonu ki tō kaiwhakarato mō ngā rota me ngā āhua motuhake.)
