Thaum tshav kub kub kho Basics rau 6061 Aluminium
6061 yog nag lossis daus-hardening aluminium alloy uas nws cov khoom kawg yog nyob ntawm kev kho cua sov. Nyob rau hauv feem ntau daim ntawv thov, cov hlau yog tov tshav kub kho kom yaj alloying ntsiab, ces quenched thiab laus. Cov ntaub ntawv teev npe temper uas siv txoj kev laus. T4 txhais tau hais tias cov khoom yog ib txwm muaj hnub nyoog ntawm chav tsev kub tom qab kev kho cua sov, thaum T6 txhais tau hais tias nws muaj hnub nyoog li qub ntawm qhov kub siab kom ncav cuag lub zog siab tshaj plaws. Ob qho tib si tempers yog cov qauv muab cov ntaub ntawv thiab txaus siab sib txawv fabrication thiab load yuav tsum.
Qhov ntom ntom thiab lub cev muaj zog
Ib qho txiaj ntsig zoo ntawm 6061 yog qhov ceev tsis hloov nrog npau taws. Qhov ceev yog 2.70 g / cm3, sib npaug rau 0.0975 lb / in3, rau ob qho tib si T4 thiab T6. Cov neeg tsim qauv thiaj li tau txais lub zog ntau dua los ntawm kev txav mus rau T6 yam tsis muaj qhov hnyav hnyav, uas yooj yim rau kev suav cov qauv thiab cov nqi kwv yees.
Mechanical Properties: T4 vs T6
Lub tshuab ua haujlwm ntawm 6061 sib txawv nrog kev npau taws, tshwj xeeb yog lub zog. T6, ua neeg laus laus, tsim kom muaj zog ntau dua thiab lub zog tensile tshaj T4, yog vim li cas T6 yog qhov nyiam rau cov qauv siv uas xav tau ntau dua load-cov kabmob muaj peev xwm. T4, nyob rau hauv sib piv, khaws ib tug qis zog theem nrog zoo formability, ua rau nws yooj yim rau khoov thiab tsim ua ntej tej kev laus tom ntej. Lub modulus ntawm elasticity ntawm cov hlau yog qhov tseem ceeb tib yam nyob rau hauv ob qho tib si tempers, thiab ob qho tib si khaws zoo corrosion kuj thiab machinability.
Thermal Properties
Ob leeg 6061-T4 thiab 6061-T6 nthuav tawm kev coj tus cwj pwm ruaj khov, uas ua rau cov hlau tsim nyog rau cov khoom sib txawv ntawm qhov kub thiab txias. Lub coefficient ntawm thermal expansion yog zoo sib xws rau ob tempers, yog li kev hloov ntawm lawv tsis tas yuav redesigning thermal nyiaj. Qhov kev ruaj ntseg no yog ib qho laj thawj 6061 yog siv rau hauv cov khoom siv hluav taws xob, cov thav ntawv, thiab lwm yam khoom siv uas qhov sib xws ntawm qhov sib xws.
Xaiv Txoj Cai Temper
Xaiv T4 thaum cov dej ntws qis yog qhov dav thiab qhov kawg yuav muaj hnub nyoog tom qab, lossis thaum daim ntawv thov tsuas yog xav tau lub zog nruab nrab nrog kev ua haujlwm siab tshaj plaws. Xaiv T6 thaum ib feem yuav tsum ua tiav ntawm lub zog tam sim ntawd, xws li cov txheej txheem thav duab, brackets, thiab cov khoom siv tshuab. Vim hais tias ob qho tib si tempers sib koom tib yam alloy chemistry, corrosion resistance, weldability, thiab machinability tseem tseem ceeb tsis hloov, cia engineers optimize rau lub zog los yog formability yam tsis tau txi lwm yam khoom.
FAQ
Q: T4 txhais li cas hauv 6061-T4?
A: T4 qhia tau hais tias cov hlau yog tov thaum tshav kub kub kho thiab ces ib txwm muaj hnub nyoog ntawm chav tsev kub. Nws muab zoo formability nrog rau nruab nrab lub zog.
Q: Qhov txawv ntawm 6061-T4 thiab 6061-T6 yog dab tsi?
A: Qhov txawv tsuas yog cov kauj ruam laus. T4 siv lub ntuj aging, thaum T6 siv dag dag, uas tsim kom muaj zog ntau dua.
Q: Puas yog 6061-T6 muaj zog dua 6061-T4?
A: Yog. Artificial aging nyob rau hauv T6 mob ua rau ntau dua yield thiab tensile lub zog, ua T6 nyiam temper rau structural thiab load- bearing daim ntaub ntawv.
Q: 6061-T4 puas tuaj yeem tsim tau yooj yim dua li T6?
A: Feem ntau yog. T4 muaj zog qis dua thiab ntau dua formability, uas txo qhov kev pheej hmoo ntawm kev tawg thaum khoov thiab sib sib zog nqus.
Q: Puas yog qhov ceev ntawm 6061 hloov ntawm T4 thiab T6?
A: No. Density remains 2.70 g/cm3 in both tempers, so moving to the stronger T6 condition does not add weight.
