Tus nqi rau lwm yam tempers sib txawv, thiab cov qauv siv tau thiab daim ntawv pov thawj zeb yuav tsum raug xa mus rau cov ntaub ntawv pov thawj.
Temper Designations
6061 tuaj yeem muab tau rau hauv ob peb lub sijhawm nrog cov yam ntxwv sib txawv . 6061-O yog tag nrho annealed nrog lub zog qis tshaj; T1 yog txias los ntawm siab - kub shaping thiab ib txwm muaj hnub nyoog; T4 yog cov tshuaj cua sov-kho thiab ib txwm muaj hnub nyoog; T5 yog txias los ntawm elevated - kub shaping thiab artificially hnub nyoog; T6 yog kev daws cov cua sov- kho thiab muaj hnub nyoog li qub; T9 yog kev daws cov cua sov-kho, cov hnub nyoog qis dua thiab ua haujlwm txias; thiab T651 yog kev ntxhov siab-relieved los ntawm stretching tom qab kev kho mob thiab tom qab laus. Raws li kev siv, lub zog tensile siab tshaj plaws tau nce los ntawm kwv yees li 124 MPa hauv O rau 310 MPa hauv T6 thiab T651, nrog lub zog tawm los ntawm li 55 MPa rau 276 MPa.
Kev tsim khoom thiab kev ua haujlwm
Extrusion shapes 6061 rau hauv cov profiles, raj, tuav thiab cov khoom siv los ntawm preheating lub billet rau 400-500C, yuam nws los ntawm kev tuag, txias, ncab kom txo tau kev ntxhov siab thiab txiav kom ntev. Rolling ua cov ntawv thiab phaj los ntawm preheating ingots, txo thickness los ntawm rollers, annealing, txias dov rau ntsuas thiab txiav. Forging shapes lub alloy nyob rau hauv siab siab kom muaj zog nyob rau hauv qhov tseem ceeb qhov chaw. Kev kho cua sov rau T6 temper suav nrog kev kho cua sov ntawm li 530-550C, dej quenching, natural aging rau T4 thiab dag dag ntawm 160-180C rau 8-10 teev. Txias stamping suits cov duab yooj yim, thaum kub-daim ntawv quench yog siv rau kev sib sib zog nqus kos los yog complex geometries; centrifugal casting yog ib qho kev xaiv rau cov nplhaib loj thiab lub tes tsho.
Daim ntawv thov
Aerospace: aircraft fittings, couplings thiab structural Cheebtsam. Automotive: ncej, log thiab tsav ncej. Kev tsim kho: kab teeb, qhov chaw ua haujlwm, ru tsev thiab qhov rais thav duab.
