Ma kahi o 7075, 7050 a me 2024 i kūpono
Ua noi nui ʻia ʻo 7075 no nā ʻāpana mīkini ikaika kiʻekiʻe. Manaʻo pinepine ʻia ʻo 7050 no ka pā aerospace mānoanoa kahi e pono ai ke kūpaʻa ʻana i ka corrosion a me ka paʻakikī. ʻO 2024 kahi hui aerospace maʻamau me ka hana luhi maikaʻi.
| Alloy | Ke kumu maʻamau | Nānā mea kūʻai |
|---|---|---|
| 7075-T651 | Paʻa mīkini ikaika kiʻekiʻe | Palahalaha, mānoanoa, hoʻomaha pilikia |
| 7050-T7451 | ʻO ka pā aerospace mānoanoa | Hōʻike, UT, traceability |
| 2024-T351 | Nā ʻāpana aerospace pili i ka luhi | ʻO ke ala wela a me ka hōʻoia |
He mea nui ka paʻa o ka mīkini
No ka hana CNC, hiki ke koʻikoʻi ke kūlana koʻikoʻi o ka pā e like me ka ikaika nominal. Pono nā mea kūʻai e hōʻoia i ka huhū, ka ʻoki ʻana i ka ʻae a me ka ʻae ʻana i ka hapa hope ma mua o ka hoʻohālikelike ʻana i nā ʻōlelo.
ʻAʻole koho ʻia nā ʻāpana 7xxx ikaika kiʻekiʻe no nā hale welded. Inā makemake ʻia ka wiliwili, e kūkākūkā i nā mea ʻokoʻa 6061, 6082 a i ʻole 5xxx.
No nā ala huahana i loaʻa, e kipa nā huahana papa alumini.
