E like me ka mea hoʻohui aerospace-grade premium,2019 pepa alumini(i kapa ʻia ʻo alloy 2019) kū i waho no kāna mau waiwai mechanical a me nā noi kūikawā. Hoʻopili kēia alakaʻi i kāna hoʻohana ʻana i ka ʻoihana, nā ʻano ʻenehana, a me nā mea koho koʻikoʻi, e hāʻawi i ka mana i nā mea kūʻai aku e hoʻoholo i ka ʻike i ke kūʻai.

1. Nā ʻano ʻokoʻa o ka Pepa Aluminum 2019

(1) Hoʻohui Kimia & Hoʻohui Alloy

- Nā mea hoʻohui mua: 4.0-5.0% keleawe (Cu), 0.2-0.4% manganese (Mn), 0.2-0.8% silicon (Si), alumini kaulike (Al).

- ʻO ka wela hiki ke mālama ʻia (e laʻa, T6, T8) no ka ikaika i hoʻopaʻa ʻia ma o ka paʻakikī o ka ua.

(2) Pono Mechanical

- Ka ikaika tensile: A hiki i ka 480 MPa (T8 temper), ma mua o 6000 a me 7000 series alloys i nā noi kikoʻī.

- Ka ikaika hua: ~415 MPa (T8), e hōʻoia ana i ka liʻiliʻi liʻiliʻi ma lalo o ka ukana.

- Elongation: 8-12%, ke kaulike ʻana i ka brittleness me ka formability.

(3) Hiki i ke kaʻina hana a me ka pale ʻana i ka corrosion

- Mīkini: ʻO ka hoʻokumu ʻana i nā puʻupuʻu maikaʻi loa i ka CNC milling a me ka huli ʻana, ʻoiai ua ʻōlelo ʻia ka lubrication no nā hana kiʻekiʻe.

- Weldability: Kaulike; Ua ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana o TIG ma mua o ka MIG no ka hoʻonohonoho pono ʻana.

- Ka pale ʻana i ka corrosion: ʻoi aku ka maikaʻi ma mua o 2024 alloy i nā kūlana lewa, ʻoiai ke aʻo ʻia nei ka mālama ʻana i ka ʻili (anodizing a pena paha) no nā kaiapuni kai.

(4) Nā Waiwai Thermal & Uila

- Ka hoʻoheheʻe wela: 121 W/m·K, kūpono i nā mea hoʻoheheʻe wela.

- Ka hoʻokele uila: 30% IACS, haʻahaʻa ma mua o ka alumini maʻemaʻe akā kūpono no nā noi non-conductive.

2. Nā noi kumu o 2019 Aluminum Pepa

(1) ʻOihana Aerospace: Nā Mea Hana

ʻO 2019 alloy, i hoʻomohala mua ʻia no nā fuselages mokulele a me nā ʻēheu, ʻoi aku ka maikaʻi ma nā wahi koʻikoʻi kiʻekiʻe. ʻO kona kūpaʻa luhi ʻoi aʻe a me ka ratio kaumaha-a-ikaika e kūpono ia no:

- ʻO nā poʻo o ka mokulele, nā kaula, a me nā mea hoʻokele pae

- Nā pahu kaʻa Rocket a me nā mea hana aerospace

- Nā ʻāpana wela kiʻekiʻe i nā ʻenekini jet (a hiki i 120 ° C), mahalo i kona kūpaʻa wela.

(2) Palekana a me na lako kaua

ʻO ke kūpaʻa ʻana o ka alloy i nā hopena ballistic a me ka corrosion ma nā wahi paʻakikī e kūpono iā ia no:

- Nā panela kaʻa i kāhiko ʻia a me ka pale pale

- ʻO nā pahu missile a me nā hale mīkini pūʻali koa.

(3) Nā Mea ʻOihana Hoʻokō Kiʻekiʻe

I nā kaʻa kaʻa a me nā kaʻa nani,Hoʻonui ka alumini 2019ka lōʻihi me ke kaumaha ʻole:

- Nā ʻāpana chassis kaʻa heihei a me nā ʻāpana hoʻomaha

- ʻO nā pale mīkini ikaika kiʻekiʻe a me nā hale hoʻouna.

(4) Mīkini pololei a me nā mea hana

ʻO kona machinability a me ka dimensional stability e kūpono ia no:

- Jigs, fixtures, a me nā mold i ka mīkini CNC

- Nā mea ana a me nā mea hana ana i ka Aerospace.

3. Pehea e koho kiʻekiʻe-Quality 2019 Aluminum Pepa

(1) E hōʻoia i ka Alloy Certification & Traceability

- Noi i nā palapala hōʻoia wili (MTCs) e hōʻoia ana i ka haku mele a me nā waiwai mechanical.

- E hōʻoia i ka hoʻokō me nā kūlana honua: ASTM B209, AMS 4042 (aerospace), a i ʻole EN AW-2019.

(2) E loiloi i ka hana ʻino a me ka mīkini

- ʻO ka huhū T6: Ka ikaika kiʻekiʻe me ka hoʻohaʻahaʻa ductility (kūpono no nā hale static).

- ʻO ka huhū T8: Hoʻonui i ke kūpaʻa corrosion stress, kūpono no nā ʻāpana ma lalo o ka hoʻouka ʻana.

-E wehewehe i nā hoʻokolohua tensile a me nā ana paʻakikī (e laʻa, Rockwell B scale) e hōʻoia i ka hana.

(3) E nānā i ka maikaʻi o ka ʻili a me ka hoʻomanawanui

- Hoʻopau i ka ʻili: E nānā i nā ʻōpala, nā hōʻailona wili, a i ʻole ka oxidation, pono nā pepa aerospace-grade i ka maikaʻi o ka papa A.

- Hoʻomanawanui mānoanoa: Hoʻopili i nā kūlana ASTM B209 (e laʻa, ± 0.05 mm no nā pepa 2-3 mm).

- Palahalaha: E hōʻoia i ke kakaka a me ka camber ʻaʻole ma mua o 0.5 mm / m no nā noi pololei.

(4) E loiloi i nā mea hiki ke hoʻolako

- Nā kaʻina hana hana: E makemake i nā mea hoʻolako me nā wahi wela a me ka mālama wela no ka maikaʻi mau.

- Hoʻopilikino: E ʻimi i nā mea hoʻolako e hāʻawi ana i nā lawelawe ʻokiʻoki i ka nui a me ka mālama ʻana i ka ʻili (anodizing, coating).

- Ka mana maikaʻi: ʻO nā palapala hōʻoia e like me ISO 9001 a i ʻole AS9100 (aerospace) hōʻailona i nā protocol hoʻāʻo ikaika.

4. 2019 Aluminum vs. Hoʻokūkū Alloys

- 2019 vs 2024 alumini:Hāʻawi ʻo 2019 i ka wela kiʻekiʻeka ikaika a me ka haʻahaʻa haʻahaʻa, ʻoiai ʻo 2024 ka ductility kiʻekiʻe. E koho i ka 2019 no nā ʻāpana aerospace e koi ana i ke kūpaʻa wela.

- 2019 vs 7075 aluminika: 7075 ka ikaika kiʻekiʻe akā ʻoi aku ka maikaʻi o ka mīkini, ʻoi aku ka maikaʻi o 2019 no nā ʻāpana mīkini paʻakikī i ka aerospace.

ʻO 2019 ka hui ʻana o ka pepa alumini o ka ikaika kiʻekiʻe, ke kūpaʻa wela, a me ka machinability i hoʻonoho ʻia ma ke ʻano he kumu pōhaku kihi i ka aerospace, pale, a me ka hana kiʻekiʻe. I ke koho ʻana i kēia alloy, e hoʻokaʻawale i ka hōʻoia, ke kūpono o ka huhū, a me ka ʻike mea kūʻai aku e hōʻoia i ka hana maikaʻi loa. No nā hoʻonā maʻamau a i ʻole nā ​​kauoha nui, e kelepona i kā mākou hui - loea i ka hāʻawi ʻana i ka alumini aerospace-grade 2019 me ka maikaʻi i hōʻoia ʻia i ka wili a me nā mana mīkini pololei.
