Puas yuav aluminium alloy xeb?
Aluminium alloy yuav xeb. Txawm hais tias aluminium alloy muaj qhov zoo tiv thaiv xeb, vim tias txhuas alloy kuj yog cov khoom siv hlau, nws kuj yuav xeb. Txawm li cas los xij, tom qab cov txhuas hauv aluminium alloy yog oxidized, qhov ntom ntom aluminium oxide "tiv thaiv zaj duab xis" yog tsim, uas tuaj yeem tiv thaiv oxidation ntxiv ntawm txhuas. Nws cov kev ua haujlwm tiv thaiv corrosion feem ntau yog los ntawm oxide zaj duab xis txheej ntawm qhov chaw uas cais nws los ntawm kev sib cuag nrog cov huab cua sab nraud thiab dej vapor, tsis txhob muaj tshuaj tiv thaiv ntawm ib leeg thiab yog li tiv thaiv corrosion.
Ib qho alloy raws li txhuas nrog qee qhov nyiaj ntawm lwm cov khoom alloying ntxiv yog ib qho ntawm cov khoom siv hlau. Ntxiv nrog rau cov khoom siv dav dav ntawm txhuas, aluminium alloys kuj muaj qee cov khoom tshwj xeeb ntawm cov alloys vim muaj ntau hom thiab ntau ntawm cov ntsiab lus ntxiv alloying.
Qhov ntom ntawm aluminium alloy yog 2.63 ~ 2.85g / cm3. Nws muaj lub zog siab, lub zog tshwj xeeb yog ze rau cov hlau alloy siab, thiab qhov tshwj xeeb nruj tshaj cov hlau. Nws muaj kev ua haujlwm zoo casting thiab kev ua haujlwm yas, zoo hluav taws xob thiab thermal conductivity, thiab zoo tiv thaiv corrosion-resistant thiab weldable, nws tuaj yeem siv los ua cov khoom siv.
Aluminium alloys muab faib ua deformed aluminium alloys thiab cam khwb cia txhuas alloys raws li lawv muaj pes tsawg leeg thiab kev ua. Deformed aluminium alloy yog tsim los ntawm thawj melting thiab casting cov khoom xyaw alloy rau hauv ingots, thiab ces plastically deforming lawv. Ntau yam khoom ua tiav plastically yog tsim los ntawm dov, extrusion, ncab, forging thiab lwm txoj kev.
Nyob rau hauv thaum ntxov hnub ntawm aluminium alloy kev tshawb fawb thiab kev loj hlob, nws yog feem ntau txuam nrog kev lag luam aviation. Nws tsuas muaj keeb kwm ze li ib puas xyoo, tab sis nws tau tsim kho sai thiab nws cov kev siv txuas ntxiv nthuav dav. Ntawm cov khoom siv hlau, nws cov khoom tso tawm yog qib thib ob tom qab hlau, thiab qib thib ob ntawm cov khoom siv hlau tsis yog hlau. Ntawm cov khoom siv hlau, nws yog thawj.
Aluminium alloy muaj cov yam ntxwv ntawm kev ceev tsawg, cov khoom siv zoo, kev hloov kho hluav taws xob zoo, hloov hluav taws xob, cua sov thiab kho cua kub. Nws yog dav siv nyob rau hauv marine kev lag luam, tshuaj lom neeg kev lag luam, aerospace, hlau ntim, tsheb thauj mus los, thiab lwm yam lug siv nyob rau hauv lub teb.
