Njengengxubevange yezinga eliphezulu le-aerospace,2019 aluminium sheet(evame ukubizwa ngokuthi i-alloy 2019) ivelele ngezakhiwo zayo ezihlukile zemishini kanye nezicelo ezikhethekile. Lo mhlahlandlela uhlolisisa ukusetshenziswa kwawo kwezimboni, izici zobuchwepheshe, nezici zokukhetha ezibucayi, unikeza abathengi amandla okwenza izinqumo ezinolwazi ekuthengeni.

1. Izici Ezihlukile Zeshidi le-Aluminium lango-2019

(1) Ukwakhiwa Kwekhemikhali kanye Nesakhiwo Sengxubevange

- Izakhi eziyinhloko ze-alloying: 4.0-5.0% yethusi (Cu), 0.2-0.4% manganese (Mn), 0.2-0.8% i-silicon (Si), ibhalansi ye-aluminium (Al).

- Ulaka olukwazi ukumelana nokushisa (isb., T6, T8) ukuze uthole amandla athuthukisiwe ngokuqiniswa kwemvula.

(2) Izakhiwo zikaMechanical

- Amandla okuqina: Kufika ku-480 MPa (i-T8 temper), edlula ama-alloys amaningi ochungechunge angama-6000 no-7000 ezinhlelweni ezithile.

- Amandla okukhiqiza: ~ 415 MPa (T8), eqinisekisa ukuwohloka okuncane ngaphansi komthwalo.

- Ubude: 8-12%, ukulinganisa ukuqina nokwakheka.

(3) Ukucutshungulwa Nokumelana Nokugqwala

- Ukwenza imishini: Ukwakheka kwe-chip okuhle kakhulu ekugayeni nasekujikeni kwe-CNC, nakuba ukuthambisa kunconywa ekusebenzeni ngesivinini esikhulu.

- Weldability: Okumaphakathi; Ukushisela kwe-TIG kukhethwa kune-MIG ngobuqotho besakhiwo.

- Ukumelana nokugqwala: Kuphakeme kuno-2024 ingxubevange ezimweni zomoya, nakuba ukwelashwa okungaphezulu (i-anodizing noma ukudweba) kuyalulekwa ezindaweni zasolwandle.

(4) Izakhiwo ezishisayo nezikagesi

- I-Thermal conductivity: 121 W/m·K, ifanele izingxenye ezikhipha ukushisa.

- I-electrical conductivity: 30% IACS, iphansi kune-aluminium emsulwa kodwa yanele izinhlelo zokusebenza ezingasebenzisi.

2. Izicelo Eziyinhloko Zeshidi Le-Aluminium Lango-2019

(1) Imboni ye-Aerospace: Izingxenye Zesakhiwo

Ingxubevange ka-2019, eyakhelwe ekuqaleni ama-fuselages ezindiza kanye nezakhiwo zamaphiko, ihamba phambili ezindaweni ezinengcindezi ephezulu. Ukumelana nokukhathala kwayo okuphakeme kanye nesilinganiso sesisindo-kuya-amandla kuyenza ilungele:

- Ama-bulkheads endiza, izintambo, nezingxenye zegiya lokuhlala

- Ama-rocket motor casings kanye namathuluzi we-aerospace

- Izingxenye ezishisa kakhulu ezinjinini zejethi (kufika ku-120°C), sibonga ukuzinza kwayo kwezinga lokushisa.

(2) Izikhali Zokuvikela Nezempi

Ukumelana kwe-alloy nemithelela ye-ballistic kanye nokugqwala ezindaweni ezinokhahlo kukufanele:

- Amaphaneli ezimoto ezihlomile kanye nezivikelo zokuzivikela

- Ama-missile casings kanye nezindlu zemishini yezinga lezempi.

(3) Izingxenye Zezimoto Ezisebenza Kakhulu

Emidlalweni yezimoto nezimoto zikanokusho,2019 i-aluminium ithuthukisaukuqina ngaphandle kokunciphisa isisindo:

- Izingxenye ze-chassis yemoto yomjaho kanye nezingxenye zokumiswa

- Abakaki benjini yamandla aphezulu kanye nezindlu zokudlulisela.

(4) Imishini Enembayo kanye Namathuluzi

Ukusebenziseka kwayo kanye nokuzinza kwe-dimensional kuyenza ifanelekele:

- Ama-Jigs, ama-fixtures, kanye nesikhunta kumishini ye-CNC

- Amageji ebanga le-Aerospace namathuluzi okulinganisa.

3. Ungalikhetha Kanjani Ishidi Le-Aluminium Lekhwalithi Ephezulu yango-2019

(1) Qinisekisa I-alloy Certification & Traceability

- Cela izitifiketi zokuhlolwa komshini (MTCs) eziqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zemishini.

- Ukuqinisekisa ukuthotshelwa kwezindinganiso zamazwe ngamazwe: ASTM B209, AMS 4042 (Aerospace), noma EN AW-2019.

(2) Hlola Ukushisa Nokusebenza Komshini

- Intukuthelo ye-T6: Amandla aphezulu ane-ductility encishisiwe (efanele izakhiwo ezimile).

- Intukuthelo ye-T8: Ukumelana nokugqwala kwengcindezi okuthuthukisiwe, ilungele izingxenye ezingaphansi kokulayisha okujikelezayo.

- Cacisa izivivinyo eziqinile kanye nezilinganiso zokuqina (isb, isikali se-Rockwell B) ukuze uqinisekise ukusebenza.

(3) Hlola Ikhwalithi Yobuso Nokubekezelelana Kobukhulu

- Ukuqedwa kwendawo: Hlola ukuklwebheka, amamaki e-roller, noma i-oxidation, amashidi ebanga le-aerospace adinga ikhwalithi yendawo ye-Class A.

- Ukubekezelela ukuqina: Namathela ezindinganisweni ze-ASTM B209 (isb, ±0.05 mm kumashidi angu-2-3 mm).

- Ukucaba: Qinisekisa ukuthi umnsalo ne-camber akudluli ku-0.5 mm/m ukuze kusetshenziswe ukunemba.

(4) Hlola Amakhono Omhlinzeki

- Izinqubo zokukhiqiza: Uncamela abahlinzeki abanezindawo zokushisa nokushisa ukuze uthole ikhwalithi engashintshi.

- Ukwenza ngokwezifiso: Bheka abahlinzeki abahlinzeka ngezinsizakalo zokusika-usayizi nokwelashwa kwendawo (i-anodizing, i-coating).

- Ukulawulwa kwekhwalithi: Izitifiketi ezifana ne-ISO 9001 noma i-AS9100 (i-aerospace) zibonakalisa izinqubo zokuhlola eziqinile.

4. I-Aluminium yango-2019 vs. Competing Alloys

- 2019 vs 2024 i-aluminium:U-2019 unikeza izinga lokushisa eliphezulu elingconoamandla kanye nokuminyana okuphansi, kuyilapho i-2024 ine-ductility ephakeme. Khetha u-2019 wezingxenye ze-aerospace ezidinga ukuzinza kwe-thermal.

- I-aluminium engu-2019 vs 7075: I-7075 inamandla aphezulu kodwa i-machinability empofu, i-2019 ikhethwa izingxenye eziyinkimbinkimbi zomshini ku-aerospace.

Inhlanganisela eyingqayizivele yeshidi le-aluminium yango-2019 yamandla aphezulu, ukuzinza kwe-thermal, nekhono lokwenza izinto ikubeka njengento eyisisekelo ku-aerospace, ukuzivikela, kanye nokukhiqiza okunembayo okuphezulu. Lapho ukhetha le ngxubevange, beka phambili isitifiketi, ukufaneleka kwentukuthelo, nolwazi lwabahlinzeki ukuze uqinisekise ukusebenza kahle. Ukuze uthole izixazululo ezenziwe ngokwezifiso noma ama-oda amaningi, xhumana nethimba lethu - eliyisipesheli ekuhlinzekeni i-aerospace-grade 2019 i-aluminium enekhwalithi eqinisekisiwe yokugaya kanye nekhono lomshini lokunemba.
