Aluminium coilyog cov khoom dov, ua nyob rau hauv ib daim ntawv coiled ntawm ib tug nruam sawb, thiab muaj ib txoj kab uas hla sab hauv thiab sab nraud. ID los ntawm 50 hli mus rau 1000mm. Aluminium alloy qib suav nrog 1xxx, 2xxx, 3xxx, 4xxx, 5xxx, 6xxx, 7xxx, 8xxx. Tab sis feem ntau yog 1050, 3003, 6061, thiab 5251 aluminium coil. Thickness ntawm 0.045-80mm, dav ntawm 60-2650mm. Cov dav dav ntawm aluminium coil yog 800mm, 1000mm, 1250mm, 1450mm, thiab 1500mm
Aluminium coil tuaj yeem tsim los ntawm txhuas ingots los yog lwm yam ntaub ntawv ntawm raw txhuas (hu ua txias dov los yog ncaj qha cam khwb cia) los yog los ntawm cov txheej txheem smelting ncaj qha los ntawm dov (hu ua nruam nruam). Cov nplooj ntawv ntawm cov dov aluminium yog ces dov, los yog coiled, nyob ib ncig ntawm ib tug tub ntxhais. Cov coils no yog cov ntses ntim, ua rau lawv yooj yim rau nkoj thiab khw muag khoom thaum piv rau txhuas hauv daim ntawv foos. Coil yog siv los tsim ib qho yuav luag tsis muaj kev txwv ntau ntawm cov khoom siv hauv ntau qhov kev lag luam.
Ntshiab aluminium yog mos heev rau feem ntau cov ntawv thov. Yog li ntawd, feem ntau aluminium coil yog tsim thiab muab los ua ib qho alloy. Cov alloys no muaj tsawg kawg yog ob lossis ntau lub ntsiab lus uas tsawg kawg yog ib qho txhuas. Aluminium alloys rau daim ntawv cov khoom raug txheeb xyuas los ntawm plaub tus lej lej uas yog tswj hwm los ntawm Aluminium Association. Thaum alloyed nrog lwm yam hlau, txhuas lub tshuab thiab lwm yam khoom tuaj yeem raug kho kom haum raws li cov kev cai tshwj xeeb rau lub zog, kev tsim, thiab lwm yam khoom.
Aluminium coil muaj nyob rau hauv qhov sib txawv ntawm qhov ntev, qhov dav thiab thicknesses, kuj hu ua "gauge". Qhov tseeb qhov ntev yog txiav txim siab los ntawm qhov loj ntawm cov khoom tsim, thiab cov txheej txheem tsim khoom siv los tsim lawv. Muaj ntau qhov chaw tiav muaj xws li zeb, matte thiab ci. Kev xaiv yuav nyob ntawm qhov kev siv thiab qhov xav tau ntawm qhov ua tiav.
Aluminium coil kuj muaj nyob rau hauv ntau yam tempers. Nws tuaj yeem muab "raws li kev tsim", hu ua "F" temper, uas tsis muaj kev txwv kev siv tshuab, thiab qhov twg tsis muaj kev tswj tshwj xeeb tau siv rau cov cua sov lossis ua haujlwm hnyav. Txij li txoj hauv kev no yog kev hloov pauv, nws feem ntau yog siv rau cov khoom uas nyob rau theem nrab ntawm kev tsim khoom. Strain-hardened yog lwm qhov kev xaiv, uas siv rau cov khoom siv wrought uas muaj zog los ntawm kev ua haujlwm txias los yog txias ua haujlwm. Cov txhuas kuj tseem tuaj yeem ua rau annealed, txhais tau tias cov khoom tau raug rhuab nrog kev tswj xyuas kom tsim tau qhov kev sib xyaw ua ke ntawm lub zog thiab formability.
Vim li cas thiaj xaiv Aluminium dua Lwm Cov Hlau?
Aluminium raug txiav rau cov neeg siv khoom tshwj xeeb
Qhov hnyav- Qhov txiaj ntsig loj tshaj plaws uas txhuas muaj ntau dua cov khoom sib tw nrog cov khoom zoo sib xws yog nws qhov hnyav dua. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov xws li pib, aerospace thiab lwm yam uas tag nrho cov khoom hnyav yog kev txhawj xeeb. Nws kuj tseem pheej yig dua rau nkoj raws li qhov tshwm sim.
Ua haujlwm tau- aluminium yog malleable heev, txhais tau tias nws tuaj yeem tsim tau yooj yim, stamped lossis zoo li xav tau. Nws workability thiab versatility pab tau zoo heev rau nws muaj koob meej. Aluminium yog nyiam rau ntau cov txheej txheem tsim, xws li kos duab, yob txoj kev, thiab stamping.
Corrosion Resistance- Nws kuj yog resistant rau corrosion thiab xeb, muab nws ib tug tseem ceeb ntug ntawm steel.
Tus nqi- txhuas tus nqi qis dua li cov ntaub ntawv xws li tooj liab, tso cai rau cov tuam txhab khaws cov khoom siv nyiaj poob qis yam tsis muaj kev txi.
Kev rov ua dua tshiab- txhuas yog yooj yim siv dua tshiab tso cai rau nws siv dua thiab dua yog li txo kev cuam tshuam ib puag ncig.
Conductive Properties-Aluminium yog ib tug zoo conductor ntawm tshav kub thiab hluav taws xob. Thaum ntsuas los ntawm qhov sib npaug ntawm qhov sib npaug, cov qib hluav taws xob aluminium muaj qhov sib npaug ntawm 62 feem pua ntawm cov hluav taws xob qib tooj liab. Txawm li cas los xij, thaum piv nrog qhov sib npaug ntawm qhov hnyav ntawm ob qho tib si, cov conductivity yog 204 feem pua ntawm tooj liab.
