Peb yuav tham txog ob qho tib sialuminium alloyyCov ntaub ntawv —— 7075 thiab 6061. Ob qho txhuas alloys no tau siv dav hauv aviation, tsheb, tshuab thiab lwm yam, tab sis lawv cov kev ua tau zoo, cov yam ntxwv thiab kev siv ntau yam sib txawv heev. Tom qab ntawd, qhov sib txawv ntawm 7075 thiab 6061 aluminium alloy yog dab tsi?

1. Cov ntsiab lus sib xyaw

7075 Txhuas alloysyog tsim los ntawm txhuas, zinc, magnesium, tooj liab thiab lwm yam khoom. Cov ntsiab lus zinc yog siab dua, ncav cuag li 6%. Cov ntsiab lus zinc siab no muab 7075 aluminium alloy zoo heev thiab hardness. Thiab6061 aluminium alloyyog aluminium, magnesium, silicon ua cov ntsiab lus tseem ceeb, nws cov ntsiab lus magnesium thiab silicon, muab kev ua haujlwm zoo thiab kev tiv thaiv corrosion.

2. Kev sib piv ntawm cov khoom siv tshuab

Cov7075 txhuas alloysawv tawm rau nws lub zog siab thiab siab hardness. Nws lub zog tensile tuaj yeem ncav cuag ntau dua 500MPa, lub hardness yog ntau dua li cov aluminium alloy zoo tib yam. Qhov no muab 7075 aluminium alloy qhov tseem ceeb hauv kev ua kom muaj zog, siab hnav tsis kam. Hauv qhov sib piv, 6061 aluminium alloy tsis muaj zog li 7075, tab sis nws muaj qhov zoo dua elongation thiab toughness, thiab yog qhov tsim nyog rau kev tsim cov khoom uas yuav tsum muaj qee yam dabtsi yog khoov thiab deformation.

3. Qhov sib txawv ntawm kev ua haujlwm

Cov6061 aluminium alloymuaj zoo txiav, vuam thiab sib sau zog. 6061 Aluminium haum rau ntau yam kev ua haujlwm thiab kev kho cua sov. Vim lub siab hardness thiab siab melting point, 7075 aluminium alloy yog qhov nyuaj heev rau txheej txheem, thiab nws yuav tsum tau siv ntau yam khoom thiab txheej txheem. Yog li ntawd, thaum xaiv cov ntaub ntawv aluminium alloy, kev xaiv yuav tsum ua raws li cov txheej txheem tshwj xeeb thiab cov txheej txheem txheej txheem.

4. Corrosion kuj

6061 aluminium alloy muaj kev tiv thaiv corrosion zoo dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw oxidation los ntawm kev tsim cov yeeb yaj kiab oxide tuab. Txawm hais tias 7075 aluminium alloy kuj muaj qee qhov kev tiv thaiv corrosion, tab sis vim nws cov ntsiab lus zinc siab, nws yuav ua rau muaj kev cuam tshuam ntau dua rau qee qhov chaw tshwj xeeb, yuav tsum tau ntsuas kev tiv thaiv corrosion ntxiv.

5. Piv txwv ntawm daim ntawv thov

Vim muaj lub zog siab thiab lub teeb yuag ntawm 7075 aluminium alloy, nws feem ntau yog siv los tsim cov khoom siv dav hlau, tsheb kauj vab thav duab, cov khoom siv ua kis las siab thiab lwm yam khoom siv nrog lub zog thiab qhov hnyav. Thiab6061 aluminium alloyyog dav siv nyob rau hauv kev tsim kho, tsheb, nkoj thiab lwm yam teb, siv rau kev tsim cov qhov rooj thiab qhov rais thav duab, pib qhov chaw, hull qauv, thiab lwm yam.

6. Hais txog tus nqi

Vim tias cov nqi tsim khoom ntau dua ntawm 7075 aluminium alloy, nws cov nqi feem ntau yog siab dua li ntawm 6061 aluminium alloy. Qhov no feem ntau yog vim tus nqi siab ntawm zinc, magnesium thiab tooj liab muaj nyob rau hauv 7075 aluminium alloy. Txawm li cas los xij, hauv qee daim ntawv thov uas xav tau kev ua haujlwm siab heev, cov nqi ntxiv no tsim nyog.

7. Cov ntsiab lus thiab cov lus qhia

Nyob nruab nrab ntawm 7075 thiab 6061 txhuas muaj qhov sib txawv tseem ceeb hauv cov khoom siv kho tshuab, cov khoom siv kho tshuab, kev tiv thaiv corrosion, daim ntawv thov ntau yam, thiab tus nqi.

Hauv kev xaiv cov khoom siv aluminium alloy, nws yuav tsum tau txiav txim siab raws li qhov tshwj xeeb siv ib puag ncig thiab xav tau.Piv txwv li, 7075 Aluminium alloy yog qhov kev xaiv zoo dua uas yuav tsum muaj lub zog siab thiab ua haujlwm zoo rau qaug zog. 6061 aluminium alloy yuav muaj txiaj ntsig zoo dua uas yuav tsum tau ua haujlwm zoo thiab ua haujlwm vuam.

Txawm hais tias 7075 thiab 6061 aluminium alloys txawv nyob rau hauv ntau yam, lawv yog ob qho tib si zoo aluminium alloy cov ntaub ntawv nrog dav daim ntawv thov kev cia siab. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm aluminium alloy manufacturing technology, ob lub aluminium alloys yuav siv tau ntau dua thiab siv rau yav tom ntej.
