Aluminium alloy qhov rooj thiab qhov rais, xov tooj ntawm tes, txhuas cov kaus poom, thiab txawm tias lub dav hlau tis peb ntsib txhua hnub, txhua yam zoo li ua los ntawm "txhuas", tab sis qhov tseeb, lawv muaj ntau hom thiab siv ntau yam sib txawv. Ntawm lawv, "wrought aluminium," raws li "tag nrho-rounder" ntawm tsev neeg aluminium, permeates txhua yam ntawm kev tsim khoom thiab lub neej txhua hnub.
Ntau tus neeg tsis meej pem "wrought aluminium" nrog cov khoom siv txhuas zoo tib yam. Niaj hnub no, peb mam li qhia txhua yam: Dab tsi yog aluminium wrought? Thiab dab tsi yog qee yam khoom siv txhuas nyob ib puag ncig peb?
01
Wrought aluminium, dab tsi yog "wrought"?
Cias muab, wrought aluminium (wrought aluminium alloy) yog aluminium alloy uas tau dhau los ua ntau yam yas deformation txheej txheem los tsim cov nplooj ntawv, tuav, profiles, lossis forgings. Nws cov yam ntxwv tseem ceeb yog "shapeability thiab siab zog," nws txawv ntawm cam khwb cia txhuas, uas yog ncaj qha nrum rau hauv cov duab.
Nws "kev yug me nyuam" zoo li "forging hlau rau hauv ib qho khoom siv tau zoo": ua ntej, aluminium ingots melted thiab cam khwb cia rau hauv billets. Tom qab homogenization, lawv tau rov ua dua los ntawm dov, extrusion, kos duab, thiab forging thaum kawg ua ntau yam duab peb xav tau- xws li dov nyias nyias rau cov kaus poom dej haus, extruding profiles rau lub qhov rooj thiab qhov rais, thiab forging forgings rau aircraft qhov chaw.
Tau hais tag nrho cov ntawd, cia peb qhia peb qhov txiaj ntsig zoo ntawm wrought aluminium:
· Lub teeb yuag: Nrog rau qhov ntom ntom, tsuas yog li 1/3 ntawm cov hlau, nws tuaj yeem txo cov khoom hnyav thaum tuav lub zog ntawm cov qauv, ua rau nws "hnyav-txuag marvel" hauv aerospace thiab automotive industries.
· Yooj yim rau txheej txheem: Cov yas zoo heev tso cai rau nws los ua cov duab nyuaj los ntawm ntau yam txheej txheem deformation. Nws tuaj yeem raug kho cua sov xws li annealing thiab quenching kom hloov kho nws cov khoom.
· Ntau qhov zoo sib xyaw ua ke: zoo hluav taws xob thiab thermal conductivity, muaj zog corrosion kuj, thiab qee cov qauv, tom qab kev kho kom muaj zog, tuaj yeem sib tw lub zog ntawm cov hlau, ua rau lawv haum rau ntau yam kev siv.
Nov yog lub ntsiab lus tseem ceeb kom paub qhov txawv: qhov sib txawv ntawm qhov sib txawv ntawm cov txhuas thiab cov cam khwb cia txhuas nyob hauv lawv "txoj kev tsim" -cam khwb cia txhuas yog "kua- lub xeev txoj kev" (xws li pouring cement, molten aluminium yog poured rau hauv pwm kom txias thiab solidify), haum rau ua qhov chaw nrog complex duab tab sis tsis tshua muaj zog yuav tsum tau (xws li cov cav tov). wrought aluminium yog "khoom-state forming," haum rau cov khoom siv uas xav tau lub zog siab thiab siab plasticity (xws li lub dav hlau tis thiab lub cev tsheb).

Tsev neeg wrought aluminium tau muab faib ua ob pawg nrog kev siv sib txawv
Tsev neeg wrought aluminium yog qhov loj, thiab raws li seb nws puas tuaj yeem ntxiv dag zog los ntawm kev kho cua sov, nws tuaj yeem muab faib ua ob pawg loj:
1. Wrought aluminium uas tsis tuaj yeem ua kom sov- kho: Cov khoom no yog mos, corrosion-resistant, thiab feem ntau siv rau hauv txhua hnub.
Cov hom wrought aluminium feem ntau tso siab rau cov khoom siv ntxiv dag zog thiab txias deformation ntxiv dag zog los txhim kho lawv lub zog. Lawv cov txiaj ntsig tseem ceeb yog cov yas zoo thiab muaj zog corrosion kuj, tab sis lawv lub zog yog qhov tsawg. Lawv tsim nyog rau cov khoom uas tsis xav tau lub zog siab tab sis xav tau yooj yim ua thiab corrosion kuj. Cov hom muaj xws li:
* Aluminium-manganese alloys: Ib qho piv txwv yog LF21 (Suav cim). Lawv muaj kev tiv thaiv corrosion zoo heev thiab cov yas zoo, thiab feem ntau yog siv los tsim cov kaus poom dej haus, cov tais diav ua noj, thiab cov vov tsev. Muaj ntau lub kaus poom uas peb haus yog tsim los ntawm hom txhuas no.
* Aluminium-magnesium alloys: Cov no muaj zog dua aluminium-manganese alloys, ncav tshaj 300 MPa, thiab muaj zog corrosion kuj, ua rau lawv tshwj xeeb tshaj yog haum rau marine ib puag ncig. Lawv tau siv dav hauv cov qauv welded, xws li cov tsheb thauj khoom pov tseg, cov roj tso tsheb hlau luam, cov nkoj me me, thiab qee cov khoom hauv kev kho kom zoo nkauj.
2. Thaum tshav kub kub- kho tau wrought aluminium: siab hardness.
Cov hom wrought aluminium alloys feem ntau txhim kho lawv lub zog los ntawm nag lossis daus hardening (aging hardening), uas ua rau muaj zog ntau dua li cov qub. Qee cov qauv siv nyob rau hauv high -cov ntawv thov kev lag luam kawg. Cov hom muaj xws li:
* **Aluminium-copper/aluminium-copper-magnesium (duralumin):** Marked as LY, ib qho piv txwv yog LY12 (suav nrog rau lub ntiaj teb 2024 alloy). Nrog lub zog tensile ncav cuag 470-480 MPa, nws lub zog siab ua rau nws muaj kev xaiv ntau hauv kev lag luam aerospace, siv los tsim cov dav hlau fuselages, tis, thiab lwm yam khoom siv. Nws kuj yog siv nyob rau hauv ib co high-strength mechanical qhov chaw.
* **Aluminium-magnesium-silicon:** Qhov feem ntau siv nruab nrab-lub zog alloy, cim raws li LD, ib qho piv txwv yog LD1 (suav nrog lub thoob ntiaj teb 6063 alloy). Nws muaj qhov zoo weldability thiab corrosion kuj, thiab yooj yim rau deg kho (xws li anodizing). Nws yog ib qho tseem ceeb hauv kev tsim cov profiles, qhov tseem ceeb rau lub qhov rooj, qhov rais, kab hlau rhuav phab ntsa, thiab rooj tog zaum.
* Aluminium-zinc-magnesium- tooj liab alloy (super-hard aluminium): cim raws li LC, ib qho piv txwv yog LC9 (suav nrog thoob ntiaj teb 7075 alloy). Nws lub zog tensile tuaj yeem ncav cuag 540-570 MPa, muaj zog heev. Nws yog tsuas yog siv nyob rau hauv aerospace thiab tub rog teb, xws li aircraft tsaws iav thiab high-strength structural Cheebtsam.
Dhau li ntawm wrought aluminium, muaj ntau lwm yam khoom siv txhuas nyob ib puag ncig peb, nrog rau ntau hom thiab siv. Tom qab tshawb fawb hauv online, peb tau sau cov npe ntawm plaub ntawm cov khoom siv txhuas feem ntau ntsib. Cia peb saib.

Tsis yog wrought aluminium xwb! Cov ntaub ntawv txhuas no kuj muaj nyob hauv lub neej txhua hnub
1. Pure aluminium: Hom yooj yim tshaj plaws ntawm txhuas, mos tab sis siv tau.
High purity (feem ntau tshaj 99%), zoo heev hluav taws xob thiab thermal conductivity, tab sis tsis muaj zog. Cov yas zoo, feem ntau yog siv rau hauv kev tsim cov xov hlau, cables, thiab cov ntaub ntawv rwb thaiv tsev, nrog rau feem ntau siv aluminium ntawv nyiaj (khoom noj khoom haus, ntawv ci hauv chav ua noj). Qee cov ntshiab txhuas kuj siv rau hauv cov khoom siv niaj hnub yooj yim.
2. Cam khwb cia txhuas: Muaj peev xwm ntawm cov duab complex, tus nqi siab -effectiveness.
Cov "kua- tsim" cov khoom siv txhuas uas tau hais ua ntej muaj cov ntsiab lus silicon siab (7% ~ 25%), zoo fluidity, thiab tuaj yeem yooj yim molded rau hauv cov duab, xws li tsheb cav blocks, gearbox vaj tse, log hub blanks, thiab ib co me me mechanical qhov chaw. Nws tus nqi qis thiab kev sib sau ceev ceev ua rau nws tus nqi - kev xaiv zoo hauv kev lag luam.
3. Aluminium Profiles: Thawj qhov kev xaiv rau lub qhov rooj, qhov rais, thiab kab hlau rhuav phab ntsa; qhov tsim nyog.
Feem ntau yog nyob rau hauv aluminium-magnesium-silicon alloy (6063 alloy) nyob rau hauv wrought aluminium, lawv yog tsim los ntawm extrusion molding, nrog ntau yam ntoo khaub lig-sectional shapes (pav, channel, thiab round raj, thiab lwm yam). Lawv tau siv dav hauv kev tsim lub qhov rooj thiab qhov rais, kab hlau rhuav phab ntsa, railings, nrog rau cov khoom siv kev txhawb nqa thiab thav duab, thiab txawm tias cov khoom siv zoo nkauj rau cov rooj tog zaum thiab cov khoom siv hauv tsev. Aluminium alloy qhov rooj thiab qhov rais feem ntau pom nyob rau hauv peb lub tsev yog cov feem ntau raug txhuas profiles.
4. Cov Ntawv Txhuas Txhuas / Foils: Pom nyob hauv txhua tsev neeg; dav siv.
Aluminium ntawv yog dov los ntawm wrought aluminium. Txawv thicknesses muaj kev siv sib txawv; nyias aluminium ntawv yog siv rau lub tsheb lub cev thiab lub tsev ru tsev, thaum cov ntawv tuab yog siv rau cov hlab ntsha siab. Aluminium ntawv ci yog ib qho ultra-nyias txias- dov aluminium khoom nrog zoo sealing thiab corrosion kuj. Dhau li ntawm cov ntim khoom noj, nws kuj tseem siv rau hauv kev ntim tshuaj thiab cov ntaub thaiv kev tiv thaiv rau cov khoom siv hluav taws xob, xws li aluminium foil ntim rau tshuaj thiab shielding ntawv ci hauv xov tooj ntawm tes.
Wrought aluminium tsis yog "ib hom txhuas", tab sis cov ntsiab lus dav dav rau "ua haujlwm tau zoo aluminium alloys." Nrog nws lub zog siab, lub teeb yuag, thiab kev ua haujlwm yooj yim, nws txhawb nqa ib feem tseem ceeb ntawm kev lag luam hauv aerospace, kev tsim kho, thiab kev lag luam tsheb. Meanwhile, ntshiab txhuas, cam khwb cia txhuas, thiab txhuas profiles kuj ua lawv lub luag hauj lwm nyob rau hauv ntau daim ntawv thov.
Lwm zaus koj pom cov khoom siv aluminium alloy, sim paub qhov txawv seb nws puas yog aluminium profile lossis cam khwb cia txhuas feem. Tom qab nyeem qhov no, koj kuj tuaj yeem dhau los ua "tus kws tshaj lij aluminium."
