Raws li koj paub.pebaluminium pobzeb trim/ aluminium skirting / coj txhuas profile / txhuas kho kom zoo nkauj profile yog ua los ntawm 6063 txhuas alloy.aluminium ntsiab yog qhov tseem ceeb.thiab cov khoom seem yuav zoo li hauv qab no.
Thiab niaj hnub no peb yuav piav qhia lub luag haujlwm thiab kev cuam tshuam ntawm ntau lub ntsiab lus hauv aluminium alloy ntawm cov khoom ntawm cov khoom siv txhuas.
tooj liab
Thaum lub txhuas-nplua nuj feem ntawm aluminium-tooj liab alloy yog 548, qhov siab tshaj plaws solubility ntawm tooj liab nyob rau hauv txhuas yog 5.65%, thiab thaum kub poob mus rau 302, solubility ntawm tooj liab yog 0.45%.Tooj liab yog ib qho tseem ceeb alloying caij thiab muaj ib tug tej yam kev daws teeb meem ntxiv dag zog rau cov nyhuv.Tsis tas li ntawd, CuAl2 precipitated los ntawm kev laus muaj qhov pom tseeb kev laus ntxiv zog.Cov ntsiab lus tooj liab nyob rau hauv aluminium alloys feem ntau yog 2.5% mus rau 5%, thiab lub zog muaj zog yog qhov zoo tshaj plaws thaum cov ntsiab lus tooj liab yog 4% mus rau 6.8%, yog li cov ntsiab lus tooj ntawm feem ntau nyuaj aluminium alloys yog nyob rau hauv qhov ntau.
Silicon element
Thaum lub aluminium-nplua nuj ib feem ntawm Al-Si alloy system nyob ntawm qhov kub thiab txias ntawm 577 ° C, lub siab tshaj plaws solubility ntawm silicon nyob rau hauv cov khoom tov yog 1.65%.Txawm hais tias cov solubility txo qis nrog qhov kub thiab txias, cov alloys feem ntau tsis tuaj yeem kho tau.Al-Si alloys muaj castability zoo heev thiab corrosion kuj.
Yog hais tias magnesium thiab silicon ntxiv rau txhuas nyob rau tib lub sijhawm los tsim cov txhuas-magnesium-silicon alloy, lub zog ntxiv yog MgSi.Qhov loj piv ntawm magnesium rau silicon yog 1.73: 1.Thaum tsim cov muaj pes tsawg leeg ntawm Al-Mg-Si alloy, cov ntsiab lus ntawm magnesium thiab silicon yuav tsum tau teeb tsa raws li qhov sib piv ntawm cov substrate.Qee cov Al-Mg-Si alloys, txhawm rau txhim kho lub zog, ntxiv qhov tsim nyog ntawm tooj liab, thiab tib lub sijhawm ntxiv cov nyiaj tsim nyog ntawm chromium los cuam tshuam cov txiaj ntsig tsis zoo ntawm tooj liab ntawm corrosion kuj.
Al-Mg2Si alloy alloy equilibrium theem daim duab Lub siab tshaj plaws solubility ntawm Mg2Si nyob rau hauv txhuas nyob rau hauv lub aluminium-nplua nuj feem yog 1.85%, thiab lub deceleration yog me me nrog qhov kub thiab txias.
Nyob rau hauv deformed aluminium alloys, qhov sib ntxiv ntawm silicon rau txhuas ib leeg yog txwv rau vuam cov ntaub ntawv, thiab ntxiv ntawm silicon rau txhuas kuj muaj ib tug tej yam ntxiv zog.
Magnesium Element
Aluminium-nplua nuj ib feem ntawm lub equilibrium theem daim duab ntawm lub Al-Mg alloy system, txawm hais tias lub solubility nkhaus qhia tau hais tias cov solubility ntawm magnesium nyob rau hauv txhuas txo zoo heev nrog rau qhov kub thiab txias, tab sis nyob rau hauv feem ntau industrial deformed aluminium alloys, cov ntsiab lus ntawm magnesium. yog tsawg dua 6%.Cov ntsiab lus silicon kuj tsawg.Hom alloy no tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov, tab sis nws muaj qhov zoo weldability, zoo corrosion kuj, thiab nruab nrab lub zog.
Lub zog ntawm magnesium rau aluminium yog pom tseeb.Rau txhua 1% nce hauv magnesium, lub zog tensile yuav nce li ntawm 34MPa.Yog tias manganese ntxiv qis dua 1%, nws tuaj yeem ntxiv cov nyhuv ntxiv.Yog li ntawd, tom qab ntxiv manganese, cov ntsiab lus magnesium tuaj yeem txo qis, thiab tib lub sijhawm, qhov kub kub tawg tuaj yeem txo qis.Tsis tas li ntawd, manganese tuaj yeem ua rau Mg5Al8 compound precipitate tusyees, thiab txhim kho corrosion kuj thiab vuam kev ua tau zoo.
Manganese
Qhov siab tshaj plaws solubility ntawm manganese nyob rau hauv cov kua yog 1.82% thaum lub eutectic kub yog 658 nyob rau hauv lub equilibrium theem daim duab ntawm Al-Mn alloy system.Lub zog ntawm cov hlau txuas ntxiv txuas ntxiv nrog kev nce ntawm kev solubility, thiab elongation nce mus txog qhov siab tshaj plaws thaum cov ntsiab lus manganese yog 0.8%.Al-Mn alloys yog non-aging hardenable alloys, uas yog, lawv tsis tuaj yeem muaj zog los ntawm kev kho cua sov.
Manganese tuaj yeem tiv thaiv cov txheej txheem recrystallization ntawm aluminium alloy, nce qhov kub ntawm recrystallization, thiab tuaj yeem ua kom zoo dua cov nplej recrystallization.Kev ua kom zoo ntawm cov nplej recrystallized feem ntau yog vim muaj kev cuam tshuam rau kev loj hlob ntawm cov nplej recrystallized los ntawm cov khoom tawg ntawm MnAl6 compound.Lwm txoj haujlwm ntawm MnAl6 yog kom yaj impurity hlau los ua (Fe, Mn) Al6, txo cov teebmeem ntawm cov hlau.
Manganese yog ib qho tseem ceeb ntawm aluminium alloys, uas tuaj yeem muab ntxiv ib leeg los ua Al-Mn binary alloys, thiab feem ntau ntxiv ua ke nrog lwm cov alloying ntsiab lus, yog li feem ntau aluminium alloys muaj manganese.
Zinc element
Lub solubility ntawm zinc nyob rau hauv txhuas yog 31.6% thaum lub txhuas-nplua nuj ib feem ntawm Al-Zn alloy system equilibrium theem daim duab yog 275, thiab nws solubility poob mus rau 5.6% thaum nws yog 125.
Thaum zinc ntxiv rau txhuas ib leeg, kev txhim kho lub zog ntawm aluminium alloy nyob rau hauv deformation tej yam kev mob yog heev txwv, thiab kuj muaj ib tug nyiam rau kev nyuaj siab corrosion cracking, uas txwv nws daim ntawv thov.
Zinc thiab magnesium ntxiv rau txhuas nyob rau tib lub sijhawm los tsim kom muaj zog theem Mg / Zn2, uas muaj qhov tseem ceeb ntxiv dag zog rau cov hlau.Thaum Mg / Zn2 cov ntsiab lus nce ntawm 0.5% mus rau 12%, lub zog tensile thiab lub zog tawm los tuaj yeem nce ntxiv.Cov ntsiab lus ntawm magnesium tshaj qhov xav tau rau kev tsim Mg / Zn2 theem.Nyob rau hauv superhard aluminium alloys, thaum piv ntawm zinc rau magnesium yog tswj ntawm txog 2.7, qhov kev nyuaj siab corrosion cracking kuj yog qhov loj tshaj plaws.
Yog hais tias tooj liab ntxiv rau Al-Zn-Mg los ua Al-Zn-Mg-Cu alloy, lub matrix ntxiv dag zog rau cov nyhuv yog qhov loj tshaj plaws ntawm tag nrho cov txhuas alloys, thiab nws kuj yog ib qho tseem ceeb aluminium alloy khoom nyob rau hauv aerospace, aviation kev lag luam, thiab hluav taws xob. fais fab kev lag luam.
