Uas tau hais tias, 6061 yuav tsum tsis txhob xav tias tsis muaj zog: nrog rau lub zog tawm los ntawm kwv yees li 276 MPa hauv T6, nws muab lub zog txhim khu kev qha piv rau qee qhov qis-carbon steels thiab haum rau ntau yam kev siv.
Machinability thiab Fabrication
6061 yooj yim dua rau tshuab thiab ua tau zoo rau cov geometries complex thiab precision machining . 7075, txawm tias nyuaj rau tshuab vim nws hardness ntau dua, tseem tuaj yeem ua tiav zoo nrog cov cuab yeej tsim nyog thiab cov txheej txheem machining. Thaum nws los txog rau vuam, qhov sib txawv yog qhov tseem ceeb: 6061 yog weldable nrog kev xaiv muab tub lim kom zoo thiab tej zaum yuav xav tau tom qab-weld kev kho cua sov kom rov ua kom tag nrho lub siab npau taws, thaum 7075 feem ntau suav hais tias tsis yog vuam vim nws yog qhov tsis tshua muaj kev tawg tom qab vuam. Ob qho khoom siv tuaj yeem koom nrog los ntawm soldering, brazing lossis adhesives qhov twg vuam tsis tuaj yeem ua tau.
Tej kev siv
6061 feem ntau hu ua structural aluminium. Nws formability, corrosion kuj thiab tus nqi nruab nrab ua rau nws yog ib qho kev xaiv rau cov khoom siv hauv tsheb, cov khoom siv hauv tsev thiab kev tsim kho, cov khoom siv hauv marine, cov khoom siv hluav taws xob thiab hluav taws xob, tsheb kauj vab thiab cov khoom siv dav dav . 7075 yog siv qhov siab tshaj plaws thiab lub zog siab - rau- qhov hnyav piv yuav tsum tau: aerospace cov qauv xws li cov dav hlau tis thiab cov khoom siv thauj mus los, cov shafts, fuselages kev ua kis las thiab siab - cov cuab yeej ua tau zoo, thiab siab - cov qauv kev ntxhov siab xws li pwm thiab cov cuab yeej ua haujlwm.
Kev txiav txim siab nqi
6061 feem ntau yog tus nqi ntau dua- ua haujlwm tau zoo, ua tsaug rau nws qhov yooj yim ntawm kev tsim khoom, muaj thiab siv tau ntau yam. 7075, vim nws lub zog zoo dua thiab cov txheej txheem ua haujlwm nyuaj, feem ntau yog kim dua. Cov kev txwv nyiaj txiag thiab kev xav tau ntawm kev ua haujlwm yuav tsum tau soj ntsuam ua ke thaum txiav txim siab.
Yuav xaiv li cas
Xaiv 6061 rau tej yaam num uas tseem ceeb rau corrosion kuj, yooj yim ntawm fabrication, machinability thiab nqi efficiency. Xaiv 7075 thaum lub zog siab, ua haujlwm ntev thiab kev ua haujlwm hauv kev ntxhov siab yog qhov tseem ceeb. Los ntawm kev txiav txim siab muaj pes tsawg leeg, lub zog, machinability, daim ntawv thov thiab tus nqi, koj tuaj yeem ntseeg siab xaiv cov hlau uas zoo tshaj plaws rau koj lub hom phiaj phiaj xwm.
FAQ
Q: Puas yog 7075 muaj zog dua 6061?
Yog lawm. Nyob rau hauv cov xwm txheej T6, 7075 muaj kwv yees li ob npaug ntawm lub zog tensile ntawm 6061 thiab ze li ob npaug ntawm lub zog tawm los, ntawm tus nqi qis dua thiab tsis zoo weldability.
Q: Puas tuaj yeem 7075 aluminium welded?
7075 feem ntau suav hais tias tsis yog vuam. Nws yog qhov yooj yim heev rau tawg tom qab vuam; mechanical fastening, adhesives lossis brazing yog siv ntau zaus.
Q: Cov alloy twg zoo dua rau kev siv marine?
6061 feem ntau yog qhov kev xaiv zoo dua rau kev siv dej hiav txwv vim tias nws zoo heev corrosion kuj thiab weldability, thaum 7075 muaj qis dua corrosion thiab tsis tuaj yeem welded ntseeg tau.
Q: Puas yog 6061 pheej yig dua 7075?
Yog lawm, 6061 feem ntau yog tus nqi ntau dua - siv tau vim tias nws yooj yim rau kev tsim thiab txheej txheem, thaum 7075 hais kom tus nqi them rau nws lub zog thiab kev ua haujlwm nyuaj dua.
Q: Dab tsi yog 6061 thiab 7075 feem ntau siv rau hauv aerospace?
7075 feem ntau yuav siv tau rau cov iav, pas nrig thiab siab - cov qauv kev ntxhov siab, thaum 6061 yog siv nyob rau hauv cov cheeb tsam uas xav tau ntau dua ductility thiab weldability xws li fittings thiab tsis yog - cov khoom tseem ceeb ntawm cov huab cua.
