Aluminium thiab Aluminium alloys: tus "golder khoom" ntawm niaj hnub tsim
Aluminium thiab nws cov aluminium, nrog lawv cov kev sib xyaw tshwj xeeb ntawm cov khoom, tau ua cov ntaub ntawv tseem ceeb hauv kev tsim khoom niaj hnub. Hauv qab no yog lawv cov ntsiab lus zoo thiab cov chaw thov raug:
1. Lub teeb ci ntsa iab thiab siab zog ua ke
Txhuas alloys muaj qhov ceev tsuas yog ib feem peb uas cov hlau. Los ntawm kev ntxiv cov ntsiab lus xws li magnesium (mg) thiab silicon (si), lawv lub zog tau tshaj 300 MPa. Alloys xws li {{2} T6 (AERPACACE qib) thiab {4 T651 (ultra-siab siv nyob rau hauv Aerospace cov cuab yeej siv roj teeb. Cov alloys ua tiav qhov hnyav txo ntawm 20% -40% thaum ua kom muaj kev nyab xeeb.
2. Ntev-ntev corrosion tsis kam
Txhuas alloys kho nrog anodizing lossis hmoov txheej, xws li 5052- h32, tuaj yeem tswj lub neej pabcuam tshaj li 20 xyoo xws li cov chaw hnyav thiab tshuaj lom neeg. Qhov no cuam tshuam cov nqi txij nkawm.
3. MalleBility ua rau cov qauv tsim nyuaj
Aluminium extrusion thiab stamping txheej txheem txhawb nqa cov kab hla kev (piv txwv li cov khoom siv hluav taws xob
4. Cov thermal thiab hluav taws xob conductivity
High-dawb huv alloys zoo li 1060 (99.6% purity) yog nyiam rau lub zog kis thiab cua sov. 3003 aluminium alloy, nrog lub thermal conductivity ntawm 229 w / (mind k), yog cov khoom siv tseem ceeb hauv kev teeb tsa cov tshuab ntsuas hluav taws xob.
5. Lub luag haujlwm tseem ceeb hauv kev lag luam kev lag luam
Rov ua dua cov aluminium alloys, xws li 5754, yuav tsum tsuas yog 5% ntawm lub zog xav tau los tsim cov thawj txhuas thiab yog 100% siv dua tshiab. Qhov no ua kom haum nrog cov hom phiaj nyob ruaj khov ntawm lub cev tsheb loj (piv txwv li lub cev tuag-cam khwb cia (piv txwv li (tshaj li 90% ntau dua 90% dhau ntawm cov dej qab zib).
Pom zoo alloys:
6061: Zoo tagnrho rau kev tsim qauv vaj tsev.
7075: Pom zoo rau cov khoom hluav taws xob siab.
5052: Tsim nyog rau lub teeb yuag yuag.
3003 Pom zoo rau hluav taws xob kub dissipation.
5754: Nyiam rau cov xwm txheej rov ua dua tshiab.
