Qhov ntom ntawm aluminium tubes yog qhov tseem ceeb ntawm lub cev tsis zoo uas cuam tshuam ncaj qha rau lawv qhov zoo, lub zog, thiab qhov dav ntawm lawv daim ntawv thov.
Ua ntej, los teb cov lus nug ncaj qha: qhov ceev ntawm txhuas raj feem ntau yog nyob ib ncig ntawm 2.7 grams ib cubic centimeter (g / cm³), tus nqi ruaj khov, txawm hais tias tus nqi pes tsawg yuav txawv me ntsis nyob ntawm cov khoom xws li cov alloy muaj pes tsawg leeg thiab kev siv tshuab.
This density characteristic of aluminum tubes is closely related to the material aluminum itself. Aluminium yog ib lub teeb yuag hlau nrog ib tug silvery - dawb luster thiab ib tug tsawg ntom, tsuas yog hais txog ib tug - peb ntawm cov hlau. Qhov tsawg ntom ntom no muab cov raj txhuas ua kom zoo dua hauv cov ntawv thov kom txo qhov hnyav, xws li kev tsim tsheb, thiab kho vaj tse. Nyob rau tib lub sijhawm, txhuas kuj muaj cov hluav taws xob zoo thiab thermal conductivity thiab corrosion kuj, ntxiv nthuav cov ntawv thov ntau yam ntawm txhuas raj.
Thaum lub sij hawm tsim cov txheej txheem ntawm txhuas raj, kev kho alloying tuaj yeem txhim kho lawv lub zog thiab hardness. Piv txwv li, los ntawm kev ntxiv cov ntsiab lus xws li magnesium, tooj liab, thiab zinc, ntau hom aluminium alloys tuaj yeem tsim. These aluminum alloy tubes not only maintain the low density characteristics of aluminum but also significantly improve their mechanical properties and corrosion resistance. Yog li ntawd, hauv kev siv tswv yim, peb tuaj yeem xaiv cov raj txhuas nrog cov hlau sib txawv raws li cov kev xav tau tshwj xeeb kom tau raws li qhov xav tau ntawm cov xwm txheej sib txawv.
Tsis tas li ntawd, qhov ntom ntawm aluminium tubes kuj tseem cuam tshuam nrog lawv cov thev naus laus zis ua haujlwm. Los ntawm cov txheej txheem xws li extrusion, ncab, thiab dov, cov ntaub ntawv txhuas tuaj yeem ua tiav rau hauv txhuas raj ntawm ntau yam duab thiab ntau thiab tsawg. Cov thev naus laus zis no tsis yog tsuas yog cuam tshuam rau qhov pom thiab qhov tseeb qhov tseeb ntawm cov raj txhuas, tab sis kuj muaj qee yam cuam tshuam rau lawv cov microstructure sab hauv thiab ntom. Piv txwv li, qhov ntom ntawm aluminium raj tom qab ua haujlwm txias tuaj yeem nce me ntsis vim kev ua kom zoo ntawm cov nplej; thaum qhov ntom ntawm aluminium raj tom qab kev kho cua sov tuaj yeem txo qis me ntsis vim kev loj hlob ntawm cov nplej. Txawm li cas los xij, zuag qhia tag nrho, cov kev hloov no muaj qhov cuam tshuam me me thiab tsis pom zoo rau qhov ntom ntawm aluminium raj.
Hauv kev siv tswv yim, cov yam ntxwv ntom ntom ntawm cov raj txhuas ua rau lawv xaiv qhov zoo tshaj plaws hauv ntau qhov chaw. Piv txwv li, txhuas raj yog siv dav hauv cov tshuab roj vim lawv qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom; nyob rau hauv lub automotive manufacturing teb, txhuas raj yog siv nyob rau hauv lub cav txias tshuab thiab braking tshuab vim lawv zoo thermal conductivity thiab corrosion kuj; thiab nyob rau hauv kev kho kom zoo nkauj architectural teb, txhuas raj yog dav siv nyob rau hauv lub qhov rooj, qhov rais, curtain phab ntsa, thiab lwm yam lug siv vim lawv txawv designs thiab kev ua tau zoo.
