Alloys ntawm Aluminium: Koj Yuav Tsum Paub Dab Tsi?

Aluminium alloys yog cov khoom tseem ceeb hauv ntau yam lag luam. Kev nkag siab txog lawv tuaj yeem pab koj xaiv qhov zoo dua rau koj cov haujlwm thiab cov ntawv thov.

Aluminium alloys yog tsim los ntawm txhuas raws li cov khoom siv hauv paus, ua ke nrog ib lossis ntau lwm cov ntsiab lus. Cov ntsiab lus no txhim kho cov khoom siv kho tshuab, kev tiv thaiv corrosion, lossis cov yam ntxwv tshwj xeeb ntawm txhuas, ua rau nws tsim nyog rau kev siv cov qauv.

Ntau tus neeg yuav tsum paub qhov twg aluminium alloy xaiv. Cov lus teb tsis yooj yim. Nws nyob ntawm seb koj xav tau cov alloy rau. Txhua alloy muaj cov khoom tshwj xeeb thiab qhov zoo. Kuv tau pom cov neeg siv khoom feem ntau tawm tsam xaiv cov kev xaiv nrov xws li 6061 thiab 7075 txhuas. Cia peb tshawb nrhiav qhov no ntxiv.

Qhov twg zoo dua, 6061 lossis 7075 txhuas?

Kev xaiv ntawm 6061 thiab 7075 txhuas tuaj yeem nyuaj. Ob leeg alloys muaj qhov zoo. Kuv tau ua haujlwm nrog ob hom hauv ntau qhov haujlwm.

6061 aluminium yog paub txog nws cov khoom siv zoo thiab weldability. Nws feem ntau yog siv rau hauv kev siv cov txheej txheem. Lub caij no, 7075 txhuas muaj zog dua tab sis tuaj yeem nyuaj rau vuam. Nws zoo meej rau kev siv aerospace qhov twg lub zog yog qhov tseem ceeb.

Thaum kuv thawj zaug pib ua hauj lwm nrog aluminium alloys, kuv feem ntau xav tsis thoob uas kuv yuav tsum xaiv. Tom qab xyoo dhau los, kuv tau kawm tias qhov kev xaiv yog nyob ntawm daim ntawv thov tshwj xeeb. Rau cov qauv hnyav, 6061 yog qhov zoo tagnrho. Txawm li cas los xij, yog tias lub zog yog koj qhov tseem ceeb, 7075 yuav yog qhov kev xaiv zoo dua.

 

Dhia tob rau hauv qhov sib piv

 

Cia peb rhuav tshem cov khoom ntawm ob qho tib si alloys.

Khoom	6061 Aluminium	7075 Aluminium
Yield zog	240 MPa	570 MPa ua
Tensile zog	310 MPa	700 MPa
Weldability	Zoo	pluag
Corrosion Resistance	Zoo heev	Nruab nrab
Daim ntawv thov	Qauv, automotive	Aerospace, tub rog

 

Raws li koj tuaj yeem pom, 7075 muaj lub zog ntau dua tab sis tsis muaj qhov weldability ntawm 6061. Qhov no ua rau 6061 ntau yam rau ntau yam kev siv, thaum 7075 feem ntau yog tshwj tseg rau siab - kev ntxhov siab ib puag ncig.

 

Muaj pes tsawg lub alloys ntawm aluminium muaj?

Tej zaum koj yuav xav tsis thoob thaum kawm tias muaj ntau tshaj 400 qhov sib txawv ntawm txhuas. Txhua alloy muaj cov yam ntxwv tshwj xeeb. Kuv nco qab xav tsis thoob los ntawm ntau yam thaum kuv thawj zaug nkag rau hauv kev lag luam.

Cov kev faib tseem ceeb yog wrought thiab cam khwb cia alloys. Wrought alloys yog zoo li tus neeg kho tshuab cov txheej txheem, thaum cam khwb cia alloys yog poured rau hauv pwm. Txhua pawg muaj nws cov cim tshwj xeeb, xws li 1000s, 2000s, thiab lwm yam, xav txog cov ntsiab lus alloying thawj.

Hauv kuv qhov kev paub dhau los, kev paub txog kev faib tawm pab xaiv cov hlau zoo rau koj cov kev xav tau. Cov ntawv thov sib txawv xav tau cov yam ntxwv sib txawv. Txawm hais tias koj xav tau kev tiv thaiv corrosion, lub zog, lossis kev ua haujlwm, muaj ib qho hlau rau qhov ntawd.

6000	Magnesium thiab Silicon	Cov yam ntxwv ntawm cov kav dej thiab cov kav dej
7000	Zinc	Cov khoom siv ua kis las thiab kev siv tub rog

 

Nkag siab txog cov koob no tuaj yeem pab koj xaiv cov hlau zoo raws li koj qhov kev xav tau tshwj xeeb.

 

Dab tsi yog qhov feem ntau aluminium alloys?

Ob peb aluminium alloys tau siv dav hauv kev lag luam sib txawv. Hauv kuv txoj haujlwm, kuv nquag ntsib 6061, 7075, thiab 5083 txhuas.

6061 yog qhov mus-raug xaiv rau kev siv cov qauv, thaum 7075 ci nyob rau hauv siab -kev ntxhov siab ib puag ncig. 5083 paub txog nws qhov kev ua tau zoo tshwj xeeb hauv kev siv dej hiav txwv, ua rau nws yog qhov kev xaiv nrov rau kev tsim nkoj.

Thaum kuv tham nrog cov neeg siv khoom, lawv feem ntau nug txog cov khoom sib xws. Kuv ib txwm xav kom pib nrog cov kev paub zoo no - paub xaiv. Lawv muab qhov sib npaug zoo ntawm kev ua haujlwm thiab tus nqi.
