Joalo ka alloy ea boemo ba leholimo ba maemo a holimo,Letlapa la aluminium la 2019(eo hangata e bitsoang alloy 2019) e ikhetha ka thepa ea eona e ikhethang ea mochini le lits'ebetso tse ikhethang. Tataiso ena e shebisisa ts'ebeliso ea eona ea indasteri, litšobotsi tsa tekheniki, le lintlha tsa bohlokoa tsa khetho, e matlafatsang bareki ho etsa liqeto tse nepahetseng mabapi le theko.

1. Litšobotsi tse Ikhethang tsa Leqephe la Aluminium la 2019

(1) Sebopeho sa Lik'hemik'hale & Sebopeho sa Alloy

- Lintho tse ka sehloohong tsa motsoako: 4.0-5.0% koporo (Cu), 0.2-0.4% manganese (Mn), 0.2-0.8% silicon (Si), aluminium e leka-lekaneng (Al).

- Mocheso o phekolehang (mohlala, T6, T8) bakeng sa matla a ntlafalitsoeng ka ho thatafatsa pula.

(2) Thepa ea Mechini

- Tensile Matla: Ho fihla ho 480 MPa (T8 temper), e fetang li-alloys tse ngata tse 6000 le 7000 lits'ebetsong tse ikhethileng.

- Matla a lihlahisoa: ~ 415 MPa (T8), ho netefatsa hore ho na le deformation e fokolang tlas'a mojaro.

- Elongation: 8-12%, ho leka-lekanya brittleness le sebopeho.

(3) Ts'ebetso le ho hanyetsa Corrosion

- Machining: Sebopeho se setle sa chip ho CNC ho sila le ho phethoha, leha ho khothaletsoa ho tlotsa bakeng sa ts'ebetso ea lebelo le holimo.

- Weldability: E itekanetseng; TIG welding e ratoa ho feta MIG bakeng sa botšepehi ba sebopeho.

- Khanyetso ea Corrosion: E phahame ho feta 2024 alloy maemong a sepakapaka, leha kalafo e holim'a metsi (anodizing kapa penta) e eletsoa bakeng sa tikoloho ea leoatle.

(4) Thermal & Motlakase Thepa

- Thermal conductivity: 121 W / m·K, e loketseng likarolo tse senyang mocheso.

- Conductivity ea motlakase: 30% IACS, e tlase ho feta aluminium e hloekileng empa e lekane bakeng sa lits'ebetso tse sa sebetseng.

2. Lisebelisoa tsa Mantlha tsa 2019 Aluminium Sheet

(1) Indasteri ea Sepakapaka: Likarolo tsa Sebopeho

Alloy ea 2019, eo qalong e etselitsoeng li-fuselage tsa lifofane le meaho ea mapheo, e sebetsa hantle haholo maemong a khatello e phahameng ea maikutlo. Ho hanyetsa mokhathala o phahameng le karo-karolelano ea boima ba 'mele ho etsa hore e be e loketseng bakeng sa:

- Li-bulkheads tsa lifofane, likhoele le lisebelisoa tsa lisebelisoa tsa ho lulisa

- Likotlolo tsa koloi ea rokete le lisebelisoa tsa sefofane

- Likarolo tse phahameng tsa mocheso lienjineng tsa jet (ho fihla ho 120 ° C), ka lebaka la botsitso ba eona ba mocheso.

(2) Tšireletso le Thepa ea Sesole

Ho hanyetsa ha alloy ho phello ea ballistic le kutu libakeng tse thata ho e loketse bakeng sa:

- Liphanele tsa likoloi tse hlometseng le tšireletso e sireletsang

- Likotlolo tsa metsu le matlo a metjhini ea boemo ba sesole.

(3) Likarolo tsa Likoloi tsa Ts'ebetso e Phahameng

Lipapaling tsa likoloi le likoloi tsa mabothobotho,2019 aluminium e ntlafatsadurability ntle le ho sekisetsa boima ba 'mele:

- Likarolo tsa chassis ea koloi ea lebelo le likarolo tse emisitsoeng

- Li-brackets tsa enjene e matla le matlo a phetiso.

(4) Mechini e nepahetseng le Lisebelisoa

Ho sebetsa ha eona le ho tsitsa ha eona ho etsa hore e tšoanelehe bakeng sa:

- Li-jigs, li-fixtures le hlobo ho machining a CNC

- Litekanyo tsa boemo ba sefofane le lisebelisoa tsa ho metha.

3. Mokhoa oa ho Khetha Leqephe la Aluminium la boleng bo phahameng ba 2019

(1) Netefatsa Setifikeiti sa Alloy & Traceability

- Kopa setifikeiti sa teko ea leloala (MTCs) tse netefatsang sebopeho sa lik'hemik'hale le thepa ea mochini.

- Netefatsa hore ho latelwa maemo a matjhaba: ASTM B209, AMS 4042 (sefofane), kapa EN AW-2019.

(2) Lekola Temperature & Mechanical Performance

- T6 temper: Matla a phahameng a nang le ductility e fokotsehileng (e loketseng meaho e tsitsitseng).

- T8 temper: Ho hanyetsa khatello ea maikutlo ho matlafalitsoeng, e loketseng likarolo tse tlas'a cyclic load.

- Hlalosa liteko tse thata le litekanyo tsa boima (mohlala, sekhahla sa Rockwell B) ho netefatsa ts'ebetso.

(3) Lekola Boleng ba Bokaholimo le Mamello ea Boemo

- Qetello ea bokaholimo: Lekola mengoallo, matšoao a rolara, kapa oxidation, maqephe a boemo ba sefofane a hloka boleng ba bokaholimo ba Sehlopha sa A.

- Mamello ea botenya: Khomarela litekanyetso tsa ASTM B209 (mohlala, ± 0.05 mm bakeng sa maqephe a 2-3 mm).

- Flatness: Etsa bonnete ba hore seqha le camber ha li fete 0.5 mm / m bakeng sa lisebelisoa tse nepahetseng.

(4) Lekola Bokhoni ba Bafani

- Mekhoa ea tlhahiso: Khetha bafani ba thepa ba nang le lisebelisoa tse futhumatsang le tse futhumatsang mocheso bakeng sa boleng bo tsitsitseng.

- Tloaelo: Batla bafani ba fanang ka lits'ebeletso tse sehiloeng ka boholo le kalafo ea bokaholimo (anodizing, coating).

- Taolo ea boleng: Litifikeiti tse kang ISO 9001 kapa AS9100 (sefofane sa sefofane) li bontša liprothokholo tse matla tsa tlhahlobo.

4. Aluminium ea 2019 vs. Competing Alloys

- 2019 vs 2024 aluminium:2019 e fana ka mocheso o phahameng o beterematla le letsoalo le tlase, athe 2024 e na le ductility e phahameng. Khetha 2019 bakeng sa likarolo tsa sepakapaka tse hlokang botsitso ba mocheso.

- Aluminium ea 2019 vs 7075: 7075 e na le matla a phahameng empa e sa sebetse hantle, 2019 e khethoa bakeng sa likarolo tse rarahaneng tse entsoeng sebakeng sa sefofane.

Motsoako o ikhethang oa sheet sheet ea 2019 oa matla a phahameng, botsitso ba mocheso, le machinability e e beha e le lejoe la motheo sebakeng sa sefofane, ts'ireletso le tlhahiso e nepahetseng haholo. Ha u khetha motsoako ona, beha setifikeiti pele, ho lekana ha bohale, le boiphihlelo ba mofani oa thepa ho netefatsa ts'ebetso e nepahetseng. Bakeng sa litharollo tsa tloaelo kapa liodara tse ngata, ikopanye le sehlopha sa rona - se ikhethetseng ho fana ka aluminiamo ea boemo ba sefofane sa 2019 e nang le boleng bo netefalitsoeng ke leloala le bokhoni ba ho sebetsa ka nepo.
