Q1: Dab tsi ua rau txhuas txawv ntawm cov khoom muaj hlau?
Txhuas uas muaj lub zog tshwj xeeb - {{1} {{1} {thib peb lub ntom ntawm cov hlau. Nws cov est oxide txheej muab cov kev tiv thaiv corrosion tsis muaj ntxiv ntxiv cov hmoov av. Cov hlau cov ntawv qhia zoo thermal thiab hluav taws xob conductivity, thib ob tsuas yog tooj liab ntawm cov hlau. Aluminium yog malleable heev, tso cai rau nws yuav tsum tau muab rau hauv ultra - cov ntawv ci (li nyias raws li 0.006mm). Ntxiv mus, nws tswj hwm ductility ntawm cryogenic kub, ua rau nws zoo tagnrho rau aerospace thiab lng kev siv.
Q2: Cov nyiaj alloy tau cuam tshuam cov txhuas kev ua tau zoo li cas?
Topper ntxiv (2xxx series) tsim cov nag lossis daus - hashing alloys rau cov dav hlau qauv. Silicon (4xxx) txhim kho Feating Fluidic rau cov cav sib xyaw ua ke. Magnesium (5xxx) txhim kho marine corrosion tsis kam los ntawm cov tawv txuag zog. Manganese (3xxx) muab lub zog nruab nrab rau cov dej haus tuaj yeem lub cev. Zinc ua ke nrog magnesium (7xxx) ua rau ultra {10} {high- lub zog alloys rau caij dav hlau.
Q3: Dab tsi paub qhov txawv ntawm cov cam khwb cia Txhuam Alloys?
Wrought alloys Thaub ib txwm deform cov txheej txheem zoo li dov lossis extrusion, tsim cov qauv sib xyaw. Nrum alloys muaj cov ntsiab lus silicon ntau dua (txog li 12%) txhawm rau txhim kho cov hlau fluidity. Cov khoom siv tau siv feem ntau ua cov khoom siv zoo dua tab sis yuav tsum tau ua cov kauj ruam ntxiv. Casting tso cai rau ze - net - duab ntau lawm ntawm cov geometries. Cov lej sib txawv, nrog wrought siv 4-lej (piv txwv li, 6061) thiab cam khwb cia siv 3-lej (piv txwv li, 356) kev tsim qauv.
Q4: Kuv txoj kev npau taws ua rau xaiv cov khoom siv li cas?
"O" Tempered (Annealed) muab qhov siab tshaj plaws rau kev sib sib zog nqus - Kos Duab Cookware. "H" Tempers qhia txog cov qib hardenening, nrog H18 tau puv tag nrho {}} nyuaj rau cov ntawv thov txheej txheem. "T6" Kev daws teeb meem kev daws teeb meem kub kho kom sov rau cov neeg laus laus rau lub zog ncov. "T73" Temper muaj kev ntxhov siab zuj zus - corrosion tsis kam ntawm me ntsis kev txo lub zog. "F" qhia tau li - ci tej yam mob uas tsis muaj kev tswj hwm.
Q5: Vim li cas cov txhuas lo rau kev ntim khoom siv tsis muaj zog?
Aluminium Ntawv Nyiaj muab cov teeb meem tiav tawm tsam ya raws, lub teeb, thiab cov pa oxygen rau khaws cia tshuaj lom. Nws cov gauges nyias txo qis cov khoom siv thaum tswj hwm kev ua haujlwm. Cov hlau lub thermal conductivity enables cov cua sov sai / txias thaum ua zaub mov noj. Cov kaus poom yooj yim tau yooj yim compressed rau kev thauj mus los ua ub no. Qhov tseem ceeb tshaj plaws, kev rov ua dua tshiab txhuas txuag 95% lub zog piv rau kev tsim khoom tseem ceeb.
