(1) Tsawg ntom: ib qho tseem ceeb ntawm aluminium profiles yog qhov ntom me me, thiab qhov ntom ntawm cov ntshiab aluminium yog ze li ntawm 2.7g / cmm³, txog 1/3 ntawm hlau lossis tooj liab; Raws li qhov sib txawv alloy muaj pes tsawg leeg, qhov ntom ntawm aluminium profiles muaj qhov hloov pauv, feem ntau nyob ntawm qhov ntom ntawm cov khoom ntxiv; Ntxiv magnesium, lithium, silicon thiab lwm yam alloying ntsiab rau txhuas, tshwj xeeb tshaj yog lithium, txo cov alloy ntom; Ntxiv chromium, tooj liab, hlau, manganese, npib tsib xee, zinc thiab lwm yam alloying ntsiab rau txhuas tuaj yeem ua rau cov hlau ntom ntom. Rolling tuaj yeem nce cov txheej txheem ntom ntom ntom, txias ua haujlwm tuaj yeem txo cov txheej txheem sib txawv thiab nce ntxiv, tsis muaj kev cuam tshuam thiab nce nqi.
(2) tuaj yeem ua kom muaj zog: lub zog ntawm cov ntshiab aluminium tsis siab, tab sis nws tuaj yeem ua tau los ntawm kev ua haujlwm txias lossis ntxiv magnesium, tooj liab, manganese, silicon, lithium thiab lwm yam, thiab tom qab ntawd ntxiv dag zog los ntawm kev kho cua sov kom tau txais lub zog siab. ; Aluminium profiles siv nyob rau hauv kev lag luam yuav tsum tau tov nrog ib co alloying ntsiab tsim los txhim kho lub zog ntawm txhuas profiles. Cov khoom siv ntxiv yog magnesium, silicon, tooj liab, zinc, manganese, npib tsib xee, thiab lwm yam. Cov ntsiab lus no tuaj yeem tsim cov khoom siv nrog txhuas thiab hloov cov khoom ntawm cov hlau. Rau qee lub hom phiaj tshwj xeeb, ib qho me me ntawm lwm cov ntsiab lus tuaj yeem muab ntxiv rau cov txhuas profile, xws li chromium, vanadium, txhuas thiab bismuth; Titanium feem ntau ntxiv rau kev tsim cov khoom zoo, thiab cov nyiaj tau ntxiv rau cov hlau los txhim kho cov ductility ntawm cov hlau thiab tau txais qhov zoo nkauj.
(3) Kev ua haujlwm yooj yim: zoo plasticity ntawm txhuas, ua haujlwm ceev ceev, tuaj yeem raug extruded rau hauv ntau qhov nyuaj ntawm txhuas profiles, thiab tuaj yeem tig, milling, tho txawv, npaj thiab lwm yam kev ua haujlwm; Rau cov cuab yeej siv tshuab uas xav tau rau kev ua haujlwm stamping, qhov cuam tshuam siab me dua li lwm cov hlau, lub neej tuag ntev, thiab txhua txoj kev casting tuaj yeem siv rau kev ua haujlwm casting.
(4) Corrosion kuj: qhov saum npoo ntawm txhuas profile yog ib qho yooj yim los tsim ib txheej ntawm ntom thiab ruaj oxide tiv thaiv zaj duab xis, uas yog ib qho yooj yim rau kev puas tsuaj tsuas yog nyob rau hauv cov ntaub ntawv ntawm halogen ions thiab alkaline tej yam kev mob, yog li txhuas muaj zoo atmospheric corrosion kuj thiab dej corrosion kuj.
(5) Tsis tshua muaj kub brittleness: txhuas hauv qab 0 degree C, nrog txo qhov kub thiab txias, lub zog thiab plasticity yuav tsis tsuas yog txo, tab sis kuj nce.
(6) Zoo hluav taws xob thiab thermal conductivity: hluav taws xob thiab thermal conductivity ntawm txhuas yog thib ob tsuas yog nyiaj, tooj liab thiab kub; Nyob rau hauv chav tsev kub, qhov sib npaug ntim conductivity ntawm hluav taws xob txhuas tuaj yeem ncav cuag 62% IACS; Yog hais tias xam raws li qhov hluav taws xob conductivity ib chav tsev loj, nws cov hluav taws xob conductivity yog ob npaug ntawm tooj liab; Tab sis txhua yam alloying yuav txo cov conductivity ntawm txhuas.
(7) Muaj zog reflectivity: lub reflectivity ntawm polished nto ntawm txhuas mus rau lub teeb dawb yog ntau tshaj 80%, qhov siab dua qhov purity, siab dua qhov reflectivity; Nyob rau tib lub sijhawm, txhuas muaj kev cuam tshuam zoo ntawm kev ua haujlwm ntawm infrared, ultraviolet, electromagnetic yoj, thermal tawg thiab lwm yam.
(8) Tsis yog-sib nqus: qhov cuam tshuam tsis tsim cov sparks, uas yog qhov tseem ceeb heev rau qee lub hom phiaj tshwj xeeb; Nws tuaj yeem siv los ua cov khoom siv tiv thaiv rau cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov cuab yeej tsim khoom rau cov khoom tawg thiab tawg.
(9) Kev nqus suab zoo: nws yog qhov zoo rau kev kho kom zoo nkauj sab hauv thiab tuaj yeem npaj rau hauv kev poob siab absorbing alloy; Qhov no feature yog siv rau zus tau tej cov high-qib aluminium alloy hais lus, tshwj xeeb tshaj yog tom qab kev ntxhib los mos etching, lub tiag tiag cheeb tsam nyob rau hauv yog zoo heev txhim khu kev qha, uas yuav ntxiv txhim kho cov kev ua tau zoo ntawm lub suab.
(10) Nuclear hluav taws xob tsis kam: txhuas muaj tib yam neutron absorption cross section rau high-zog neutrons li lwm yam hlau; Rau cov neutrons nyob rau hauv qis zog ntau, qhov kev nqus ntawm cross seem yog thib ob tsuas yog beryllium, magnesium, zirconium thiab lwm yam hlau. Qhov zoo tshaj plaws ntawm aluminium nuclear hluav taws xob tiv thaiv yog qhov induced hluav taws xob hluav taws xob tsim los ntawm irradiation decays sai.
(11) Zoo nkauj: aluminium profile vim muaj peev xwm rov qab muaj zog, qhov saum npoo yog nyiaj-dawb luster, tom qab ua tiav tuaj yeem ua tiav siab thiab ci ntsa iab; Yog tias ua tiav los ntawm kev kho tshwj xeeb, anodizing, dyeing lossis tshuaj ntsuam luam ntawv, nws tsis tsuas yog muaj kev tiv thaiv corrosion, tab sis kuj muaj qhov zoo nkauj zoo nkauj; Cov khoom siv kho kom zoo nkauj thiab ua haujlwm tuaj yeem txhim kho ntxiv los ntawm electroplating, electroless plating thiab lwm txoj kev ua. Tshwj xeeb tshaj yog tam sim no, nrog rau kev txhim kho cov khoom siv nyob hauv cov qauv, cov neeg muaj kev xav tau ntau dua rau kev kho kom zoo nkauj hauv chav; Tom qab kev ntxhib los mos etching aluminium profile, qhov kom zoo dua no yuav ua kom pom tseeb dua; Siv rau hauv kev kho kom zoo nkauj sab hauv, nws nthuav qhia cov khoom siv qib siab tshiab rau kev lag luam kho kom zoo nkauj sab hauv, ua rau chav nyob zoo dua thiab muaj kuab heev.
