Paub txog kev ua lub teeb yuag, corrosion-resistant, thiab ntau yam, txhuas ua si lub luag haujlwm tseem ceeb hauv kev siv ntawm Aerospace siv. Nws zoo heev thermal thiab hluav taws xob conductivity, raws li nws muaj peev xwm ua tau yooj yim rau hauv cov qauv sib txawv, ua rau nws cov khoom siv ntawm kev xaiv rau cov engineers thiab cov tuam ntxhab. Tsab ntawv no rho tawm hauv cov tshuab tseem ceeb, lub cev, thiab tshuaj lom neeg ntawm txhuas, pab koj nkag siab nws cov kev siv ntau yam thiab cov txiaj ntsig.
1. Cov Khoom Siv Neeg Kho Tshuab:
Lub zog: Tsawg rau qhov muaj zog nruab nrab, nyob ntawm cov alloy.
Kev ua siab loj: Heev condile, tuaj yeem tsim tau yooj yim rau hauv cov ntawv txheeb thiab xov hlau.
Lub zog tensile: Feem ntau yog li ntawm 70 txog 700 MPA, nyob ntawm cov alloy thiab kev kho mob.
Paib lub zog: Tsawg tawm los lub zog piv rau cov hlau, tab sis tuaj yeem txhim kho los ntawm kev ua kom sov thiab cua sov.
Kev nyuaj: Qhov tseem ceeb tshaj plaws hardness piv rau cov hlau tab sis tuaj yeem txhim kho nrog cov khoom siv alloy.
Qaug zog muaj zog: Zoo tsis kam mus rau cyclic chaw thau khoom, nyob ntawm cov alloy thiab kev kho mob.
2. Cov Khoom Siv Lub Cev:
Ceev: 2.7 g /m³, lub teeb yuag, ua rau nws zoo tagnrho rau cov ntawv thov uas qhov hnyav txo yog qhov tseem ceeb.
Melting taw tes: 660 degree (1220 degree f).
Thermal conductivity: Siab thermal conductivity, nyob ib ncig ntawm 235 w / min k, uas ua rau nws ua tus coj ua zoo.
Hluav Taws Xob Kev Tshaj Tawm: Kev ua hluav taws xob siab heev, nyob ib ncig ntawm 35-45%% IRS (International Annealed Tooj Liab Qauv).
Coefficient ntawm thermal expansion: 23.1 × 10⁻⁶ / degree, uas yog qhov siab tshaj ntawm cov hlau me.
3. Tshuaj Tshuaj Muaj Zog:
Corrosion Kuj: Zoo heev corrosion vim yog tsim ntawm nyias cov txheej oxide nyias uas tiv thaiv cov khoom los ntawm oxidation ntxiv.
Kev xav tau: Reacts nrog Halogens ntawm cov kub thiab feem ntau tiv taus ntau lwm cov kua qaub thiab tshuaj lom neeg.
Oxidation: Ua ib txheej oxide tiv thaiv (al₂o₃) uas tiv thaiv kev xeb ntxiv.
4. Kev ua haujlwm:
Luam ntawv: Yooj yim rau siv lub tshuab, tshwj xeeb tshaj yog thaum muaj nrog lwm cov khoom xws li tooj liab, zinc, lossis magnesium.
Hwj txwv: Zoo weldability, tab sis cov tswv yim kom raug yuav tsum tau zam oxidation thaum lub sij hawm vuam.
Muaj meej: Tuaj yeem tsim tau yooj yim rau hauv cov nplooj ntawv nyias lossis ntawv ci, siv dav hauv ib lub aerospace, ntim, thiab kev tsim kho.
5. Lwm yam ntxwv:
Lub teeb yuag: Ib qho ntawm cov hlau teeb pom kev zoo, siv dav hauv cov ntawv thov uas txo qhov hnyav yog qhov tseem ceeb, xws li hauv Aerospace thiab kev lag luam tsheb.
Tsis muaj hlau nplaum: Aluminium yog tsis muaj hlau nplaum, ua rau nws haum rau cov tshuab hluav taws xob thiab hluav taws xob.
Rov qab tau: Aluminium yog 100% siv dua tshiab yam tsis poob ntawm nws cov khoom, ua rau muaj kev coj ua kom ruaj khov.
Tsis-lom: Muaj kev nyab xeeb rau kev siv hauv cov khoom noj ntim khoom thiab cov cuab yeej kho mob vim nws cov xwm tsis muaj tshuaj lom.
Feem ntau alloys ntawm txhuas:
AL 2024: Muaj zog, feem ntau siv hauv aerospace.
AL 6061: Nruab nrab lub zog, zoo weldability, dav siv hauv kev tsim kho thiab tshuab.
AL 7075: Lub zog siab, siv nyob rau hauv cov ntawv thov kev ua tau zoo xws li cov dav hlau.
Hauv kev xaus, Aluminium cov khoom zoo tshaj plaws - xws li nws lub qaim xwm, zoo heev corrosion, thiab siab ua haujlwm-ua kom nws muaj kev lag luam tsis tau. Seb siv hauv aerospace, tsheb, lossis ntim khoom, nws lub zog, durability, thiab rov ua dua tshiab muab qhov tseem ceeb cuam tshuam rau lwm cov hlau. Nkag siab cov khoom no ua rau cov encessers thiab cov chaw tsim khoom siv cov peev txheej tag nrho, kom muaj kev daws teeb meem zoo rau ntau cov ntawv thov.
