Muaj yuav luag ntau hom txhuas tsim dua li lwm cov hlau hauv kev lag luam. Cov neeg nyob rau hauv kev tsim kho thiab kev lag luam sector zoo li nyiam tshaj plaws hauv txhuas vim nws yog ob qho tib si lub teeb thiab ruaj khov.
Muaj 7 alloys feem ntau siv hauv kev tsim khoom txhuas. Txhua series pib nrog cov lej 1-7 (1xxx, 2xxx, 3xxx, 4xxx, 5xxx, 6xxx thiab 7xxx). Tus lej no yeej txiav txim siab tias cov ntsiab lus alloying ntxiv rau aluminium.
Cov lus piav qhia luv luv ntawm cov sib txawv series yog teev hauv qab no:
1000 series yog cov ntshiab txhuas-nws yuav tsum muaj tsawg kawg yog 99% txhuas. Nws yog weldable, tab sis nyob rau hauv kev taw qhia nqaim. Vim nws superior corrosion kuj, nws yog tsuas yog siv rau tshwj xeeb chemical cia tanks los yog conductive busbars.
2000 series ntawm txhuas thiab tooj liab alloys yog sib xyaw thiab feem ntau siv hauv kev lag luam aerospace.
3000 series yog tov nrog manganese thiab yog heev" formable" thiab kub-kho tau. Qhov no aluminium alloy feem ntau yog siv nyob rau hauv cookware thiab tshav kub exchangers nyob rau hauv fais fab nroj tsuag thiab tsheb.
Lub 4000 series sib tov txhuas nrog silicon, tso cai rau qis melting point, yog li txhim kho fluidity thaum melting (hais tias nws melts zoo). 4000 series txhuas feem ntau yog siv los ua cov khoom siv rau vuam thiab brazing.
5000 series txhuas yog tov nrog magnesium (sib txawv los ntawm manganese), uas muaj ob qho tib si siab tensile zog thiab formability; yog li ntawd, nws yog siv dav hauv kev tsim khoom, xws li kev thauj mus los, tso tsheb hlau luam, nkoj thiab txuas hniav.
6000 series yog tov nrog magnesium thiab silicone resin thiab yog siv nyob rau hauv daim ntawv ntawm extrusion thiab structural qhov chaw, xws li lub kaum sab xis steel, kab teeb thiab kav.
Lub 7000 series yog tov nrog zinc alloy. Nws yog ua los ntawm txhuas lub zog muaj zog heev thiab feem ntau yog siv rau hauv kev ua haujlwm siab xws li dav hlau, aerospace, thiab cov khoom sib tw kis las.
Feem ntau siv txhuas hauv kev lag luam kev lag luam dav dav yog 3000, 5000 lossis 6000 series alloys.
Lub tsev ua los ntawm txhuas hlau
Nws yog ib qho tseem ceeb rau cov engineers thiab architects kom muaj kev nkag siab tob txog qhov sib txawv ntawm txhuas thiab nws cov alloys ntau siv hauv aluminium vuam thiab kev tsim khoom thaum thov cov hom tshwj xeeb rau ib qhov project. Piv txwv li, thaum nws los txog rau 6000 series txhuas, engineers feem ntau nug txog 6061-T6 txhuas. Hom aluminium alloy no muaj lub zog tensile siab, tab sis nws kuj yog nkig heev. Yog li ntawd, nws yuav ua tau raws li qhov yuav tsum tau muaj tensile ntawm qhov tsim, tab sis ua tsis tau thaum lub qhov yuav tsum tau zoo li tus los yog tsim vim hais tias cov hlau yuav tawg ntawm txoj kab bending.
Vim qhov teeb meem tawg no, prefabricated aluminium siv rau phab ntsa panels, kev lag luam kev lag luam, thiab lwm yam. yog qhov zoo tshaj plaws tsim nrog 5000 series txhuas, uas tuaj yeem ua tau zoo (yuav tsis tawg lossis tawg), tab sis kuj muaj lub zog tensile ruaj khov.
Feem ntau, extrusions xws li txhuas lub kaum sab xis steel, kav dej lossis kab teeb yuav raug siv ua ke nrog cov ntaub ntawv tiaj tus. Nyob rau hauv cov ntaub ntawv no, lub alloy yuav tsis raws nraim tib yam. Nyob rau hauv cov ntaub ntawv no, manufacturers yuav tsum tau xyuas kom meej tias cov welding muab tub lim cov ntaub ntawv raug xaiv los tswj cov ob alloys. Piv txwv li, 6000 series txhuas yuav tsum tsis txhob welded nrog 3000 series muab tub lim ntaub ntawv.
Muaj lwm yam kev tsim thiab tsim cov teeb meem ntawm txhuas-laser txiav ntawm tempered aluminium tej zaum yuav yog ib qho tseem ceeb, raws li tau piav qhia saum toj no, kho cov txhuas vuam thiab tsim cov txheej txheem, pleev xim thiab kho qhov chaw-tag nrho cov uas yuav tsum tau tshwj xeeb saib xyuas kom nws zoo txhuas.
