8079 I-Aluminium Foil: Ukuhlaziywa Okuphelele kwe-High-Fe, I-Low-Si Alloy Yakhelwe I-Premium Foil
8079 iyibanga elimele le-8XXX yochungechunge lwe-aluminium alloy foil, uchungechunge olubonakala ngensimbi (Fe) Njengento ebonakalayo ebonakalayo. Ngokusebenzisa eyingqayizivele yayo “high Fe, low Si” ifomula yokuqamba, 8079 ifinyelela izici eziphelele ezivelele. Isetshenziswa kakhulu ekufakweni okuphezulu kanye nezinkambu zamandla amasha njengokudla nemithi., ukuhlukanisa ngokugqamile kusuka kumafoyili enhloso ejwayelekile njenge 8011.
Mina. I-Core Chemical Composition kanye ne-alloy Design Principles
1.1 Ukulawula Ukwakheka Kwamakhemikhali Okunembile (Ingxenyenamba enkulu, %)
| Isici | I-Standard Control Range | Indima ebalulekile ye-Metallurgical | Umthelela Othize Kuzakhiwo |
|---|---|---|---|
| Al. | Ukuzimelela (≥98.5%) | Isisekelo sensimbi, ukwakha i-matrix yezinto ezibonakalayo. | Iqinisekisa ukuguquguquka okuyisisekelo kukagesi/okushisayo kanye nokwakheka. |
| Fe. | 0.7 ~ 1.3. | Isici esiqinisayo.Yakha izinhlanganisela ezihlukahlukene ze-intermetallic nge-aluminium, ngokuyinhloko izigaba ze-Al₃Fe ezinenaliti enhle/ezimise okwenduku. | 1. Ukuqinisa Ukuhlakazeka:Izigaba ze-Al₃Fe ziphina ukugudluka kanye nemingcele yokusanhlamvu ngesikhathi sokugoqeka okubandayo nokudonsa, okwandisa kakhulu amandla nobulukhuni. 2. Ukucwengwa Okusanhlamvu:Ivimbela ukukhula okusanhlamvu okwenziwe kabusha, okuholela emfameni, microstructure enhle. 3. Yehlisa ama-Pinholes:I-Fe ilungisa i-hydrogen ekuncibilikeni, ukunciphisa i-porosity ku-ingot, ngaleyo ndlela ehlisa izimbobo ku-foil yokugcina. 4. Ithuthukisa Ukuzinza Kwe-Thermal:Izigaba ze-High-melting-point Al₃Fe zimelana nokuqina phakathi nokucubungula okulandelayo (E.g., ephendulayo, ukuvala inzalo), ukugcina izakhiwo ezinzile. |
| Futhi. | ≤0.10. | Ukungcola okulawulwa ngokuqinile/i-trace alloy element.. | 1. Ilawula I-Fe/Si Ratio:Okuqukethwe kwe-Si okuphansi kakhulu kuyisihluthulelo sokuzuza isilinganiso esiphezulu se-Fe/Si (ngokuvamile >7). Lokhu kugwema ukwenza amaholo, brittle α-Al(FeMn)Izigaba ze-Si noma ze-β-AlFeSi ngesikhathi sokuqina. 2. Ithuthukisa Ukusebenza Okushisayo:Izigaba ezimahhadlahhadla ze-Si-rich zidala imifantu egoqayo. Idizayini ye-Low-Si iqeda le ngozi, ngcono kakhulu isivuno se-hot-rolling. 3. Ithuthukisa i-Ductility:Yehlisa izigaba ze-brittle, ukunikeza i-foil i-ductility enhle kanye nokudonsa okujulile ngisho nasezilinganisweni ezincane kakhulu. |
| Okunye Ukungcola (Cu, UMn, Zn, njll.) | Ngamunye ≤0.05, Isamba ≤0.15 | Kulawulwa ngokuqinile ukuze kuhlanzeke. | Ivimbela ukwakheka kwamaseli e-galvanic endawo ayingozi, ukuqinisekisa ukumelana nokugqwala okuhle kakhulu nokuhambisana nezidingo zokuphepha kokuxhumana nokudla/kwemithi. |
Ingqikithi ye-Alloy Design: “High Fe, Low Si”. Lokhu akukhona ukuhlanganisa/ukususa okulula kwezakhi kodwa ibhalansi ethambile. Ikhulisa umphumela wokuqinisa we-Fe (ngezigaba ze-Al₃Fe) kuyilapho kunciphisa umthelela omubi we-Si (ukuqeda izigaba ze-Si-rich brittle), ukuvumela 8079 ukuze kuzuzwe ibhalansi elilungile phakathi kwamandla, ukwakheka, Ukumelana nePinhole, kanye nokuzinza okushisayo.
2. Inqubo Yokukhiqiza, I-Microstructure, kanye Nobudlelwano Bezakhiwo
2.1 Ukugeleza Kwenqubo Yokukhiqiza
Melting & Casting (Precise Fe/Si ratio control) → Homogenization Annealing (Uniform composition) →
Hot Rolling (Slabbing, utilizing low-Si advantage to prevent cracking) →
Cold Rolling (Multiple passes to intermediate gauge) → Intermediate Annealing (Remove work hardening) →
Finish Rolling (Down to ≤6µm double-zero foil) → Slitting/Annealing (Achieve O or H18 tempers, etc.)2.2 I-Microstructural Characters
- Izinhlayiya Zesigaba Sesibili:Ngokuyinhloko ubukhulu be-nano-to-micron, izigaba ze-Al₃Fe ezihlakazeke ngokulinganayo eziyisiyingi noma zenduku emfushane. Izigaba ze-β-AlFeSi ezifana nepuleti elimahhadla noma lesikripthi sesiShayina azivamile ukubonwa.
- Ukwakheka okusanhlamvu:Ngemuva kokuhlinzwa, umfaniswano, Isakhiwo sokusanhlamvu se-fine equiaxed recrystallized sikhona. Ngokufutheka kwe-H18, kukhona isakhiwo esisetshenziselwe i-fibrous.
- Lokhu kuhlanzekile, i-microstructure efanayo iyisisekelo esibonakalayo sokusebenza kwayo okuphezulu.
2.3 Imininingwane Yezakhiwo Eziyinhloko
- Izakhiwo zikaMechanical Eziyingqayizivele:
- Ihlanganisa Amandla Aphakeme Nokudonsa Okujulile: Ukuqinisa ukuhlakazeka kusuka ezigabeni ze-Al₃Fe kunikeza isisekelo samandla aphezulu, ngenkathi i-matrix ehlanzekile (low Si) iqinisekisa ipulasitiki enhle kakhulu. Lokhu kuvumela 8079 I-O-temper foil ukumelana nomdwebo ojulile kanye ne-H18 temper foil ukuhlangabezana nezimfuneko zamandla/ukuqina kwefilimu yebhethri ye-aluminium laminate.
- I-Ultra-Thin Gauge Amandla:Ngenxa yesakhiwo esifanayo kanye nokungcola okuphansi, igcina ukuminyana kwemigodi ephansi kakhulu (E.g., ≤50 amaphinifa/m²) noma ngabe igoqwe ibe ngu-6µm noma izacile, okubalulekile ekumelaneni nokugqwala kwebhethri ye-lithium nokuvala uphawu.
- Perfect Barrier Properties:

- Excellent Thermal Stability & Ukuphepha:
- Isakhiwo esincane esizinzile kanye nezakhiwo ngesikhathi sokushintshwa kwezinga lokushisa eliphezulu (ngaphezu kuka-121°C) noma ukuvala inzalo.
- Ihambisana ngokugcwele nemithethonqubo emikhulu yokuxhumana nokudla emhlabeni jikelele (I-FDA, Uhlobo lwe 10/2011) kanye namazinga okupakisha emithi. Non-anobuthi, engenaphunga, -ngenangozi, futhi enokwethenjelwa.
- I-Surface Enhle & Lamination Properties:
- Ukuhlanzeka okuphezulu kwendawo kanye nomsebenzi, okuholela ekunamatheleni okuqinile namafilimu epulasitiki (I-PE, PP, Injobe) kanye nokufaneleka kokuphrinta/ukunameka.
I-III. Ukuhlaziywa Okujulile Kwezinkambu Zokusebenza
