Dab tsi paub qhov txawv 8079 alloy los ntawm lwm cov ntawv ci aluminium?
8079 TXHUAS NTAWV Muaj cov ntsiab lus hlau siab dua (1.0-1.5%) piv rau nws lub zog tensile thiab puncture tiv taus. Cov ntsiab lus silicon yog nruj me ntsis tswj tau hauv qab 0.3% kom txo qis brittleness thaum lub sij hawm txias. Qhov no Alloy qhia tau superient noo noo noo cov khoom, tiav<0.1g/m²/24h water vapor transmission rate. Unlike pure 1xxx series foils, 8079 maintains better formability in humid environments. Its chemical composition is optimized for high-speed packaging lines with fewer breaks.
Vim li cas 8079 dav siv nyob rau hauv cov ntim kaw lus laminates yooj ywm?
The alloy's excellent heat-sealability (sealing strength >3/15 hli) ua rau nws zoo tagnrho rau cov qauv laminated nrog tus tsiaj lossis PE Films. Nws qis elongation coefficient (<3%) prevents wrinkling during lamination processes. 8079 foil provides electromagnetic shielding effectiveness up to 60dB at 1MHz frequency. The surface oxide layer naturally resists chemical corrosion from acidic foods. These properties collectively ensure shelf-life extension for sensitive products like coffee and medical supplies.
Yuav ua li cas 8079 ua tiav hauv qhov kub thiab txias li cas?
8079 khaws cia txhua yam ruaj ntseg tsis pub dhau -70℃mus rau 200 degree, outperforming 1235 alloy hauv cryogen app. Cov ntawv ci lub thermal conductivity (237W / MIN K · KCH) ua kom muaj kev sib tw tshav ntuj muaj zog thaum muaj kev sib tw. Kev Nyuaj Siab-Kev Txhim Kho Kev Kho Mob ntawm 250℃tiv thaiv delamination hauv retort pouches. Tsis zoo li 3003 alloy, 8079 tsis tsim intermetallic precipitates thaum kub. Qhov no thermal resilience suits rau nws rau lub chaw muag zaub mov thiab tshuaj tiv thaiv.
Cov yam ntxwv saum npoo txhais tau li cas los ntawm cov kws tshuaj-qib 8079 ntawv nyiaj?
Lub tsev muag tshuaj-qib 8079 Undergoes Electrochemical Polishing kom ua tiav RA<0.05μm surface roughness. The foil must pass USP Class VI biocompatibility tests for direct drug contact. A proprietary passivation process creates 2-5nm oxide layers for enhanced corrosion resistance. Laser-etched batch numbers remain legible even after gamma irradiation. These features meet ISO 15378 standards for primary pharmaceutical packaging.
Hauv hlwv ntim, vim li cas xaiv 8079 ntau tshaj 8021?
8079 Cov khoom ua pov thawj 30% tsawg dua pinholes ntawm 20μm thickness piv rau 8021, tseem ceeb rau noo-rhiab-rhiab siv tshuaj. Nws cov ntsiab lus hlau siab dua txhim kho kev tuag-cuttability nyob rau hauv hlwv sib. Cov alloy qhia cov hlau thauj khoom qis (<0.1μg/cm²) in accelerated aging tests. For child-resistant packaging, 8079's tear resistance exceeds 15N/mm². However, 8021 remains preferable for ultra-deep drawing applications requiring >40% elongation.
