1. Hoʻohui Kemika: ʻO ke kumu o ka maʻemaʻe a me ka kūlike
Hoʻoholo ʻia ka hana ʻana o nā pā alumini 1070 e kā lākou ʻano alumini ultra-kiʻekiʻe a me nā mea haumia paʻa. Ma ke ʻano he papa alumini maʻemaʻe kūʻai, ua maʻalahi kona haku ʻana, me nā mea hoʻohui i hoʻohui ʻia i hoʻohui ʻia e hoʻomaikaʻi i ka hana me ka ʻole o ka hoʻomaʻemaʻe ʻana. ʻAʻole kēia "maʻalahi" i ka palena akā he hoʻolālā i manaʻo ʻia e mālama i nā waiwai kūlohelohe o ka alumini (e laʻa, conductivity, corrosion resistance) e kūpono i nā hiʻohiʻona e koi ana i ka maʻemaʻe kiʻekiʻe.
Ka Hoʻohui Koʻikoʻi: Ultra-High Aluminum Content
- Aluminum (Al): ≥99.70% - Ma ke ʻano he mea nui, ʻo ia ke kumu kumu o nā waiwai pūlima o 1070: maikaʻi loa ka thermal/electrical conductivity, kūlohelohe corrosion resistance, a me ka ductility kiʻekiʻe. ʻO ka hoʻomaʻemaʻe kiʻekiʻe e hōʻoia i ka hana maʻamau i kēlā me kēia puʻupuʻu, kahi mea pono ʻole i hiki ke kūkākūkā ʻia no nā noi e like me nā busbar uila a me nā mea hoʻololi wela pololei.
ʻO nā mea haumia i hoʻomaluʻia a me nā mea hana
Ua kaupalena ʻia ka maʻiʻo haumia e pale i ka hoʻololi ʻana i ka conductivity, ductility, a i ʻole ka maikaʻi o ka ʻili. E like me nā kūlana ASTM B209 a me EN 573-3, penei nā palena nui:
- Hao (Fe): ≤0.25%. ʻO ka haumia maʻamau i ka alumini; ʻO ka hao nui e hana i nā pūhui intermetallic paʻakikī (e laʻa, Al₃Fe), e hōʻemi ana i ka ductility mea a me ka pale ʻana. ʻO ka hoʻomalu ʻana i ka mea hao ma lalo o 0.25% e hōʻoia i ka 1070 mau papa alumini ʻaʻole e haki i ka wā huki hohonu, kūlou, a i ʻole nā kaʻina hana ʻē aʻe.

2. Nā hiʻohiʻona hana: ʻO ka hui pū ʻana o ka Ductility, Conductivity, a me ka hana
ʻO nā mea maikaʻi o nā papa alumini 1070 e pili ana i ka "formability" a me ka "purity based functionality" ma mua o ka ikaika kiʻekiʻe e hoʻokaʻawale iā ia mai nā mea alumini i hoʻohui ʻia. Hoʻohana piha kāna hana i nā pono kūpono o ka alumini maʻemaʻe, me nā hoʻoponopono maikaʻi ma o ka hoʻomaʻamaʻa ʻana (hana wela a i ʻole ka hana anu) e hoʻololi ai i nā pono hana like ʻole. ʻAʻole e like me nā alloys e kaumaha ana i ka ductility no ka ikaika, 1070 ke kaulike ma waena o ka pono a me ka hilinaʻi, e lilo ia i "mea alumini maʻemaʻe maʻemaʻe" no ka hana maʻalahi a me nā hiʻohiʻona hana pololei.
Hana Mechanical: Ductility e like me ke kumu
ʻOkoʻa iki nā waiwai mechanical o 1070 e ka huhū (e laʻa, Temper O no ka hoʻopili piha ʻana, Temper H14 no ka hana anuanu maʻalahi), akā ʻo kona ʻano kumu e huli mau ana i ka "maʻalahi hoʻohua":
- Ka ikaika hoʻopale (σb): 70~110 MPa. ʻOi aku ka haʻahaʻa ma mua o ka alumini i hoʻohui ʻia (e laʻa, ʻo 6061 ka ikaika tensile o 276 MPa), akā lawa no nā noi hana ʻole e like me ka hoʻopili ʻana a me nā paneli hoʻonaninani.
- Ka ikaika hua (σ0.2): 30~95 MPa. ʻO ka ikaika haʻahaʻa haʻahaʻa, ʻo ia ka piʻo ʻana a me ka maʻalahi o ka mea, no laila kūpono ia no ke kaha kiʻi hohonu (e laʻa, nā mea kuke alumini) a i ʻole ka hana ʻōwili (e laʻa, nā pā uila).
- Elongation ma ka haki (δ): 10~35%. ʻO ka ductility maikaʻi loa (a hiki i 35% no Temper O) hiki iā ia ke hoʻokumu ʻia i loko o nā geometries paʻakikī me ka ʻole o ka haki ʻana-he mea maikaʻi ʻole e like me nā metala maʻemaʻe kiʻekiʻe e like me ke keleawe.
- ʻO Brinell Hardness (HB): 15~30. ʻO ka paʻakikī haʻahaʻa e hiki ai ke hana maʻalahi (e laʻa, wili, ʻokiʻoki) ʻoiai e pale ana i nā ʻōpala liʻiliʻi i ka wā e hoʻohana ai (e laʻa, ʻoki hoʻonaninani).
Hana kino a me ke kaiapuni
Na waiwai kino oʻO 1070 kona mau ikaika hoʻokūkū koʻikoʻi, i loaʻa pololei mai kona waihona alumini kiʻekiʻe:
- Ka hoʻoheheʻe wela: 235 W/(m·K). Ma kahi kokoke i ka alumini maʻemaʻe (237 W / (m · K)), e hana ana ia i kekahi o nā alumini alumini ʻoihana me ka hana hoʻopau wela maikaʻi loa. He kūpono ia no nā hiʻohiʻona e like me nā kukui wela LED, nā hale uila uila, a me nā mea hoʻololi wela.
- Ka hoʻokele uila: 61% IACS (International Annealed Copper Standard). ʻOi aku ka maikaʻi ma mua o ka hapa nui o nā alumini alumini (e like me 6061 he 43% IACS wale nō ka conductivity uila), e lilo ia i koho maikaʻi loa no nā mea uila e like me nā busbars, nā kaula, a me nā hale capacitor.
- Kū'ē Kū'ē: Maikaʻi (Natural Passivation). Hoʻokumu ka waihona alumini kiʻekiʻe i kahi kiʻiʻoniʻoni oxide (Al₂O₃) ma luna o ka ʻili, e pale ana i ka oxidation hou. ʻAʻole like me ka alumini i hoʻohuihui ʻia, ʻaʻole koi ʻo 1070 i kahi uhi hou no ka pale ʻana i ka ʻōpala i loko o nā kaiapuni i loko a i waho paha (e laʻa, ʻokiʻoki hale).
- Māmā: 2.70 g/cm³. ʻOi aku ka maikaʻi ma mua o ke keleawe (30% ma mua o ke keleawe), e hōʻemi ana i nā kumukūʻai waiwai a me ke kaumaha hoʻonohonoho. He kūpono ia no nā hiʻohiʻona koʻikoʻi e like me nā pale wela automotive a me nā ʻāpana o loko aerospace.
Hana Hana: Hana maʻalahi a me ke kumu kūʻai haʻahaʻa
ʻO ka palupalu a me ka ductility o 1070 e hoʻolilo iā ia i mea alumini "palapala hoʻomaʻamaʻa", hoʻopōkole i nā pōʻai hana a hoʻemi i nā kumukūʻai:
- Hiki ke hoʻohālikelike: maikaʻi loa. Hiki iā ia ke pale aku i nā kaʻina hana like ʻole e like me ke kaha kiʻi hohonu, ka ʻōwili ʻana, ka kuʻi ʻana, a me ka wili me ka ʻole o ka pohā. No ka laʻana, hoʻohana maʻamau ia e hana i nā kini alumini seamless a i ʻole nā panī hoʻonaninani curved.
- Weldability: maikaʻi loa. E like me nā kaʻina hana kuʻi alumini maʻamau (e laʻa, MIG welding, TIG welding, resistance resistance) me ka liʻiliʻi ma hope o ka weld crack, he mea koʻikoʻi no nā mea nui i hui pū ʻia e like me nā cores exchanger wela.
- Hoʻomaʻamaʻa ʻili: kūpono no nā kaʻina hana hoʻopau lehulehu. He hana maikaʻi loa ia i ka anodization (kūlohelohe / kala), ka uhi pauka, a me ka electroplating. ʻO kona ʻano haumia haʻahaʻa e hōʻoiaʻiʻo ai i ka ʻaʻahu, ʻaʻohe kīnā ʻole o ka ʻili, ʻoi aku ka mea nui no nā ʻāpana hoʻonaninani (e laʻa, ʻokiʻoki hale) a i ʻole nā mea i loko o nā pōʻino kiʻekiʻe (e laʻa, nā pā uila moana).
- Mākaukau: Maikaʻi (me nā mea hana kūikawā). He palupalu ka mea, hiki ke hana wikiwiki, akā pono ka lubrication i mea e pale ai i ka "galling" (ka mea pili i nā mea hana ʻoki). He kūpono ia no nā ʻāpana kikoʻī e like me nā mea hoʻohui uila a me nā hale sensor.
