8079 Aluminium Foil: Tlhahlobo e Feletseng ea High-Fe, Low-Si Alloy E entsoe ka Foil ea Premium
8079 ke sehlopha sa baemeli ba 8XXX series aluminium alloy foil, letoto le khetholloang ka tshepe (Fe) e le ntho ea mantlha ea motho. Ka e ikhethang ea eona “phahameng Fe, tlaase Si” sebopeho sa sebopeho, 8079 e fihlella litšobotsi tse phethahetseng tse felletseng. E sebelisoa haholo libakeng tse phahameng tsa ho paka le masimong a macha a matla joalo ka lijo le meriana., ho e khetholla ka mokhoa o hlakileng ho tsoa ho lifolakha tse akaretsang 8011.
I. Sebopeho sa Lik'hemik'hale tsa Core le Melao-motheo ea Moralo oa Alloy
1.1 Taolo e Nepahetseng ea Sebopeho sa Lik'hemik'hale (Mabaka a Mangata, %)
| Element | Lethathamo la Taolo e Tloaelehileng | Karolo ea mantlha ea Metallurgical | Tšusumetso e Khethehileng ho Thepa |
|---|---|---|---|
| Al. | Balance (≥98.5%) | Motheo oa tšepe, ho etsa matrix a lintho tse bonahalang. | E netefatsa conductivity ea mantlha ea motlakase / mocheso le sebopeho. |
| Fe. | 0.7 ~ 1.3. | Ntho e matlafatsang ea mantlha.E theha metsoako e fapaneng ea li-intermetallic ka aluminium, haholo-holo mekhahlelo e metle ea nale/molamu oa Al₃Fe. | 1. Ho Matlafatsa Phatlalatso:Mekhahlelo ea Al₃Fe e tiisa ho kheloha le meeli ea lijo-thollo nakong ea serame le ho kolobisoa, ho eketsa matla le boima haholo. 2. Ntlafatso ea lijo-thollo:E thibela kholo ea lijo-thollo tse nchafalitsoeng, ho fella ka junifomo, sebopeho se setle sa microstructure. 3. E fokotsa li-Pinholes:Fe e lokisa haedrojene ka ho qhibiliha, ho fokotsa porosity ka har'a ingot, ka hona ho theola masoba foil ea ho qetela. 4. E Ntlafatsa Thermal Stability:Mekhahlelo e phahameng ea melting-point Al₃Fe e hanana le ho omella nakong ea ts'ebetso e latelang (E.g., retorting, ho koala sekheo), ho boloka thepa e tsitsitseng. |
| Le. | ≤0.10. | Ho se hloeke ho laoloang ka thata-thata / ho latela motsoako oa motsoako.. | 1. Controls Fe/Si Ratio: Likahare tse tlase haholo tsa Si ke senotlolo sa ho fihlela karolelano e phahameng ea Fe/Si (hangata >7). Sena se qoba ho etsa mahoashe, brittle α-Al(FeMn)Si kapa β-AlFeSi mekhahlelo nakong ea ho tiisa. 2. E Ntlafatsa Mosebetsi o Chesang:Mekhahlelo e mahoashe ea Si-rich e baka mapetsong a chesang. Sebopeho sa low-Si se felisa kotsi ena, ho ntlafatsa haholo tlhahiso ea hot-rolling. 3. E matlafatsa Ductility:E fokotsa likarolo tsa brittle, ho fana ka foil hamonate e ntle le e hohelang ka botebo esita le ka li-gauge tse tšesaane haholo. |
| Litšila tse ling (Cu, Mong, Zn, etc.) | E 'ngoe le e' ngoe ≤0.05, Kakaretso ≤0.15 | E laoloang ka thata bakeng sa bohloeki. | E thibela ho thehoa ha lisele tse kotsi tsa galvanic tsa sebakeng seo, ho etsa bonnete ba ho hanyetsa ho bola ho hoholo le ho latela litlhoko tsa polokeho ea lijo/litlhare. |
Bohlokoa ba Alloy Design: “Phahameng Fe, Low Si”. Hona ha se tlatsetso/ho tlosa lintho tse bonolo empa ke tekano e bobebe. E eketsa phello e matlafatsang ea Fe (ka mekhahlelo ea Al₃Fe) ha a ntse a fokotsa tšusumetso e mpe ea Si (ho felisa mekhahlelo ea brittle Si-rich), lumella 8079 ho fihlella tekanyo e nepahetseng pakeng tsa matla, Motho ea hlokang, khanyetso ea pinhole, le botsitso ba mocheso.
II. Mokhoa oa Tlhahiso, Likokoana-hloko, le Likamano tsa Thepa
2.1 Phallo ea Ts'ebetso ea Core Production
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 Litšobotsi tsa Microstructural
- Likaroloana tsa Mokhahlelo oa Bobeli:Haholo-holo boholo ba nano-to-micron, mekhahlelo ea Al₃Fe e arohaneng ka mokhoa o tšoanang e chitja kapa e mokhutšoane. Mekhahlelo e mahoashe e kang poleiti kapa ea Sechaena-script β-AlFeSi ha e hlokomeloe ka seoelo.
- Sebopeho sa lijo-thollo:Ka mor'a ho hlatsoa, seaparo sa seaparo, sebopeho se setle sa equiaxed recrystallized lijo-thollo se teng. Ka bohale ba H18, sebopeho se sebelitsoeng sa likhoele se teng.
- Sena se hloekile, junifomo microstructure ke motheo oa 'mele oa tshebetso ea eona e phahameng.
2.3 Lintlha tsa bohlokoa ka ho Fetisisa
- Thepa e ikhethang ea Mechini:
- E Kopanya Matla a Phahameng le Matla a Tebileng:Matlafatso ea ho hasana ho tloha methating ea Al₃Fe e fana ka motheo o matla haholo, ha matrix a hloekileng (tlaase Si) e netefatsa polasetiki e ntle haholo. Sena se lumella 8079 O-temper foil ho mamella motaki o tebileng le foil ea eona ea H18 ho fihlela litlhoko tsa matla / ho tiea bakeng sa filimi ea laminate ea aluminium ea betri..
- Bokhoni ba Ultra-Thin Gauge:Ka lebaka la sebopeho se ts'oanang le litšila tse tlase, e boloka letsoalo le tlase haholo la liphahlo (E.g., ≤50 likoti tsa likhohlo/m²) esita le ha o phutholetsoe ho 6µm kapa o mosesane, e leng ea bohlokoa bakeng sa lithium betri corrosion resistance le ho tiisa.
- Perfect Barrier Properties:
- 100% Libaka tse Khanya:E thibela ka ho feletseng mabone a UV, ho tshireletsa bokahare ba kganya (E.g., Pharmaceutical, oli ea boleng bo holimo).
- Sethibelo se Phahameng:Ho kenella ho tlase haholo ho oksijene le mouoane oa metsi, ho etsa hore ho baballe tatso ya dijo, ho lelefatsa sethala sa bophelo, le ho netefatsa botsitso ba lithethefatsi.
- E babatsehang Thermal Stability & Tšireletseho:
- Microstructure e tsitsitseng le thepa nakong ea ho khutlisa mocheso o phahameng (ka holimo ho 121°C) kapa ho nyopisa.
- E lumellana ka botlalo le melaoana e meholo ea lefats'e ea ho ikopanya le lijo (FDA, EU 10/2011) le litekanyetso tsa ho paka tsa meriana. E seng chefo, e senang monko, E bolokehile, le e ka tšeptjoang.
- Sebaka se setle & Thepa ea Lamination:
- Bohloeki bo holimo le mosebetsi, ho fella ka ho khomarela ka matla le lifilimi tsa polasetiki (Pe, PP, Nylon) le ho tšoaneleha bakeng sa ho hatisa / ho roala.
