Thaum koj tab tom nrhiav los daws koj cov khoom tsim cov kev xav tau nrog extruded txhuas cov kev daws teeb meem, koj yuav tsum nrhiav kom paub tias qhov kub siab tshaj plaws haum rau koj cov kev xav tau. Yog li, koj paub ntau npaum li cas txog aluminium temper? Nov yog phau ntawv qhia ceev los pab koj.

Dab tsi yog aluminium alloy temper designations?

Lub xeev lub npe sawv cev rau kev hloov pauv ntawm lub cev muaj zog uas tuaj yeem ua tiav hauv cov alloy. Cov alloys peb extrud, xws li wrought aluminium alloys, muab faib ua ob pawg: tshav kub kho tau thiab tsis kub kho. Lub 1xxx, 3xxx thiab 5xxx series tsis tuaj yeem kho cua sov, thaum 2xxx, 6xxx thiab 7xxx series yog cov cua sov kho. 4xxx series muaj ob hom. Cov hlau tsis muaj cua sov tuaj yeem tsis tuaj yeem ua kom muaj zog ntau dua los ntawm kev kho cua sov thiab tsuas yog cia siab rau qib ntawm kev ua haujlwm txias los txhim kho lawv cov khoom. Thaum tshav kub kub-kho tau alloys, ntawm qhov tod tes, tuaj yeem ntxiv dag zog los ntawm kev kho cua sov. Cov kev sib txawv ntawm cov tshuaj thiab metallurgical qauv no kuj muaj feem xyuam rau yuav ua li cas cov hlau reacts thaum vuam thiab lwm yam kev tsim khoom. Qhov tseem ceeb, ntau yam ntawm aluminium alloys thiab lawv lub xeev tempering tsim ib tsev neeg ntawm cov ntaub ntawv nyuaj, thiab kev nkag siab txog qhov sib txawv no tuaj yeem ua rau muaj kev vam meej ntau dua.

Tsib aluminium alloy temper designations

Kev nkag siab txog cov xwm txheej tsim nyog yog qhov tseem ceeb rau kev nkag siab txog cov khoom thiab daim ntawv ntawm cov khoom siv txhuas. Cov npe no yog alphanumeric thiab ntxiv rau lub npe alloy los muab cov ntaub ntawv qhia txog yuav ua li cas cov alloy yog mechanically thiab / lossis thermally kho kom tau txais cov khoom xav tau. Piv txwv li, 6061-T6 sawv cev rau lub npe tshwj xeeb. Thawj tus cwj pwm hauv lub npe npau taws (F, O, H, W, lossis T) qhia txog kev tuav haujlwm.

F-lub xeev cov khoom yog cov khoom tiav ib nrab uas yuav tsum tau ua ntxiv kom tau txais cov duab tiav lossis lub xeev.

O qhia txog cov khoom siv annealed kom ua haujlwm tau zoo tshaj plaws los yog ua kom muaj zog thiab ductility.

H stands rau strain-hardened non-heat-treatable alloy.

W yog qhov tsim nyog rau cov khoom qub qub tom qab kev kho cua sov.

T yog hais txog cov khoom lag luam ntawm cov khoom siv hluav taws xob kho cua sov uas tau ua kom sov kho, quenched, thiab hnub nyoog. Kev lees paub thiab nkag siab txog cov xwm txheej no yog qhov tseem ceeb rau cov neeg tsim khoom thiab cov neeg siv kom nkag siab txog keeb kwm kev ua haujlwm thiab cov yam ntxwv ntawm cov khoom siv txhuas.

Npaum li cas rau koj cov khoom

Cov neeg siv kawg yuav tsum nkag siab txog cov qauv no kom ntxaws kom tsis txhob cuam tshuam cov haujlwm tseem ceeb uas muab los ntawm cov chaw tsim khoom tom qab hauv cov txheej txheem. Piv txwv li, kev ua kom zoo ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob kho cua sov yuav tsum tau xaiv cov kev kho cua sov uas tsim nyog, quenching npaum li cas, thiab kev laus kev kho mob ib ntus. Qhov no tuaj yeem txhim kho corrosion kuj ntawm tus nqi ntawm lub zog. Tsis tas li ntawd, tempering ntawm cov hlau tuaj yeem cuam tshuam cov tsos ntawm cov khoom tom qab anodization vim cov tshuaj tiv thaiv ntawm cov hlau rau cov txheej txheem. Kev nkag siab txog ntau yam aluminium alloys thiab xeev thiab cov khoom siv kho tshuab uas lawv muaj tuaj yeem nyuaj, tshwj xeeb tshaj yog rau cov kws tsim qauv tsim qauv uas tau ua haujlwm nrog cov hlau. Txawm li cas los xij, nws tseem ceeb heev, thiab kuv vam tias phau ntawv qhia ceev no ntawm kev npau taws yog ib kauj ruam ntawm txoj kev yog.
