2024 Aluminium alloy yog asiab zog aluminium,belongs rau Al-Cu-Mg. Feem ntau yog siv los tsim ntau yam khoom siv siab thiab cov khoom siv, tuaj yeem ua kom sov kho qhov cuab lub zog. Nruab nrab quenching thiab nruj quenching tej yam kev mob, zoo chaw vuam. Qhov nyiam tsim cov kab nrib pleb intercrystalline hauv cov roj vuam, nws cov khoom zoo txiav tom qab quenching thiab txias hardening. Tsawg txiav tom qab annealing, tsawg corrosion kuj. Anodizing kev kho mob thiab pleev xim los yog txhuas txheej los txhim kho nws cov kev tiv thaiv corrosion uas feem ntau yog siv los ua ntau yam ntawm cov khoom siv siab thiab cov khoom siv (tab sis tsis suav nrog cov khoom seem forging) xws li cov pob txha pob txha, daim tawv nqaij, ncej, tis tav, tis kab, rivets. thiab lwm qhov chaw ua haujlwm.

Hardness (500kg quab yuam 10mm pob) - - - 120
Elongation tus nqi (1.6mm (1/16in) thickness) - - 10
Loj shear stress (MPa) - - - 285
2024 Kev siv ntawm aluminium alloy
Aircraft structural qhov chaw: Vim nws siab zog thiab zoo qaug zog zog, 2024 aluminium alloy yog dav siv hauv kev tsim cov dav hlau tis nqaj, tis tav, daim tawv nqaij fuselage thiab lwm yam khoom siv.
Missile structural parts: Tib yam siv rau lub foob pob hluav taws thiab lwm yam khoom siv.
Auto qhov chaw: Rau kev tsim khoom pib nrog lub zog siab, xws li ncej, bracket, thiab lwm yam.
Rail tsheb thauj mus los: Xws li cov tsheb thauj mus los hauv subway, cov tsheb ciav hlau ceev ceev, thiab lwm yam kom txo qhov hnyav thiab txhim kho lub zog ua haujlwm.
Shipbuilding: Rau kev tsim cov khoom xws li cov qauv hull, decks, tshwj xeeb tshaj yog qhov yuav tsum tau muaj kev tiv thaiv corrosion thiab hnav.
Cov cuab yeej siv tub rog: Kev tsim cov qauv ntawm cov tub rog dav hlau, nyoob hoom qav taub, tsheb armored thiab lwm yam khoom siv tub rog.
High-end tsheb kauj vab ncej: 2024 aluminium alloy yog siv los ua tus ncej ntawm cov tsheb kauj vab siab vim nws lub teeb yuag thiab lub zog siab.
Kev lag luam kev teeb tsa: Nws yog siv los tsim cov khoom siv thiab cov khoom txhawb nqa hauv ntau yam khoom siv hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau tiv taus cov khoom loj.
Kev tsim kho kev lag luam: Siv los ua cov khoom siv hauv tsev, qee qhov tuaj yeem hloov steel lossis lwm yam ntaub ntawv, tshwj xeeb tshaj yog hauv cov ntawv siv hnyav.
Lwm yam khoom siv ncaws pob: xws li golf clubs, ski ncej, thiab lwm yam.
2024 Aluminium alloy ua txheej txheem:
Kev kho cua sov
Kev kho cov khoom (annealing): Kub cov khoom rau ib qho kub (feem ntau 480 C rau 500 C), ceev ceev rau qee lub sijhawm (dej txias lossis roj txias),tnws cov txheej txheem tuaj yeem txhim kho plasticityntawm cov khoom siv thiab pab txhawb kev ua haujlwm tom ntej.
Lub hnub nyoog hardening: Lub sijhawm ntev cua sov ntawm qhov kub qis (feem ntau yog 120 C txog 150 C), txhawm rau ua kom muaj zog ntxiv, Raws li cov kev laus sib txawv, sib txawv ntawm hardness thiab lub zog tuaj yeem tau txais.
Kev tsim
Extrusion txoj kev: Lub aluminium alloy yog nyem los ntawm cov pwm ntawm qhov kub thiab txias siab los tsim cov duab uas xav tau. 2024 aluminium alloy yog tsim los ua cov kav dej, tuav, thiab lwm yam.
Punch forming: Siv cov xovxwm los yaug lub phaj lossis cov yeeb nkab rau hauv cov duab uas xav tau, Tsim nyog rau kev ua cov khoom ntawm cov duab nyuaj.
forging: Forging aluminium alloy rau hauv cov duab xav tau los ntawm rauj lossis xovxwm, Tsim nyog rau kev tsim khoom ntawm cov qauv loj.
Tshuab ua haujlwm
Turnery: Siv lub tshuab dhos rau machining cylindrical qhov chaw.
Milling: Txiav cov khoom nrog lub tshuab milling, haum rau machining dav hlau lossis qhov chaw nrog cov duab nyuaj.
Laum: Rau drilling qhov hauv cov khoom.
Tapping: txheej txheem threads hauv pre-drill qhov.
Kev kho saum npoo
Anodic oxidation: Ib zaj duab xis oxide tuab yog tsim rau ntawm qhov chaw ntawm cov khoom siv los ntawm cov tshuaj tiv thaiv electrochemical los txhim kho corrosion kuj thiab hnav tsis kam ntawm cov khoom.
Xim-coat: Siv cov txheej txheem tiv thaiv ntawm cov khoom siv los ntawm kev txau los txhim kho nws cov kev tiv thaiv corrosion.
Polishing: Tshem tawm qhov roughness ntawm cov khoom nto thiab txhim kho qhov gloss thiab smoothness.
