Daim ntawv 1050 aluminium alloy belongs rau 1000 series thiab yog cov purity siab, tsis yog - tshav kub- qib kho tau. Vim tias nws cov ntsiab lus txhuas yog tsawg kawg 99.5 feem pua, nws raug cais raws li kev lag luam ntshiab es tsis yog nag lossis daus hardening alloy. Qhov purity ntawd yog vim li cas cov khoom siv hluav taws xob, tshuaj lom neeg thiab zaub mov kev lag luam qhia nws: conductivity thiab corrosion kuj yog tswj los ntawm lub hauv paus hlau nws tus kheej es tsis yog los ntawm alloying ntxiv.
1050 daim ntawv tsis yog cov qauv hlau. Nws tus nqi yog nyob rau hauv formability, thermal thiab hluav taws xob conductivity, thiab ruaj khov corrosion tus cwj pwm, yog li nws yog xaiv qhov twg cov khoom yuav tsum tau sib sib zog nqus nqus, dov, khoov los yog welded es tsis loaded rau siab.
Tshuaj muaj pes tsawg leeg ntawm 1050 Aluminium Alloy
Txhuas cov ntaub ntawv tsawg kawg yog 99.5 feem pua ntawm qhov loj ntawm 1050. Cov seem yog cov txheej txheem tswj cov kab uas tau tuav hauv qab nruj txwv kom cov conductivity thiab formability tsis degraded. Kev sib xyaw ua ke tau teev tseg rau EN 573-3 rau cov khoom siv tshuaj lom neeg thiab tiv thaiv cov qib sib piv hauv tebchaws hauv GB / T 3190.
| Element | Cov ntsiab lus (piv txwv li) | Muaj nuj nqi |
|---|---|---|
| Aluminium (Al) | 99.5 yam | Base hlau; nqa conductivity thiab tsim cov oxide tiv thaiv zaj duab xis |
| Hlau (Fe) | 0.40 max | Kuaj impurity; nce lub zog me ntsis thiab ua kom cov nplej ntawm qis qis |
| Silicon (Si) | 0.25 max | Kuaj impurity; tswj los tiv thaiv conductivity |
| Copper (Cu) | 0.05 max | nruj me ntsis vim nws txo qis corrosion kuj |
| Manganese (Mn) | 0.05 max | Tshawb nrhiav impurity |
| Magnesium (Mg) | 0.03 max | Tshawb nrhiav impurity |
| Chromium (Cr) | 0.03 max | Tshawb nrhiav impurity |
| Zinc (Zn) | 0.05 max | Tshawb nrhiav impurity |
Vim hais tias txhua qhov sib ntxiv tau khaws cia ntawm qhov chaw, qhov kev coj tus cwj pwm ntawm daim ntawv ua raws li cov ntshiab aluminium. Tsis muaj cov ntsiab lus alloying tam sim no nyob rau hauv ib qho nyiaj uas tuaj yeem tsim kom muaj zog precipitate, uas yog vim li cas metallurgical qib tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov.
Mechanical Properties
1050 txhuas ntawv yog muab rau hauv annealed O temper, nyob rau hauv raws li fabricated F mob thiab nyob rau hauv kev ua hauj lwm hardened H111 thiab H112 tempers, thiab txhua yam muaj nuj nqis raug hais tawm tsam EN 485-2 rau daim ntawv, sawb thiab phaj, nrog ASTM B209 npog qhov sib npaug American specification. Lub zog muaj zog nyob ntawm kev npau taws, vim tias tsuas yog lub zog muaj zog muaj peev xwm yog strain hardening.
Tensile zog:feem ntau 70 mus rau 120 MPa thoob plaws lub tempers muab, nrog rau qhov qis tshaj qhov tseem ceeb nyob rau hauv tag nrho cov annealed mob thiab siab tshaj nyob rau hauv lub harder dov tempers.
Yield zog (0.2% pov thawj):Feem ntau 35 mus rau 85 MPa, nce raws li cov khoom siv txias ua haujlwm.
Elongation:feem ntau 30 mus rau 50 feem pua ntawm cov mob annealed, uas yog qhov tso cai rau kev sib sib zog nqus nqus thiab tsim cov ntawv ci thiab nyias gauge strip.
Hardness:Brinell hardness nyob ib ncig ntawm 40 mus rau 50 HB nyob rau hauv lub harder tempers, nrog kom meej meej txo nqi nyob rau hauv lub mos annealed mob.
Qhov ua tau zoo yog tias 1050 raug xaiv rau qhov chaw nrog cov duab geometry nyuaj es tsis yog rau cov khoom nqa cov qauv. Yog xav tau lub zog ntau dua ntawm tib lub conductivity, yuav tsum xaiv qib sib txawv.
Lub cev muaj zog
| Khoom | Yam nqi | Sau ntawv |
|---|---|---|
| Qhov ntom | Txog 2.71 g / cm3 | Ze rau 2.70 g / cm3 ntawm ntshiab aluminium; low density txhawb lub zog siab rau qhov hnyav piv |
| Hluav taws xob conductivity | 61-63% IACS | Ntsuas tawm tsam International Annealed Copper Standard; haum rau cable, busbar thiab fais fab engineering siv |
| Thermal conductivity | Txog 235 W / (mK) | Txhawb cov dab dej kub, radiators thiab kub exchangers |
| Reflectivity | Siab hla pom thiab infrared bands | Siv tau rau hauv cov reflectors, lub teeb fixtures thiab thermal shielding |
| Corrosion kuj | Zoo heev hauv huab cua, dej tshiab thiab ntau yam tshuaj | Tus kheej- rov ua dua oxide zaj duab xis tiv thaiv qhov chaw; kev ua tau zoo yog qhov zoo tshaj plaws hauv kev pabcuam nruab nrab thiab me ntsis acidic |
Corrosion kuj yog qhov thib ob vim li cas qib tau siv dav. Lub ntuj oxide txheej tsuas yog ob peb nanometers tuab tab sis nws rov- cov ntaub ntawv tam sim ntawd thaum puas lawm, yog li daim ntawv coj tus cwj pwm zoo hauv cov huab cua hauv hiav txwv thiab hauv cov nroj tsuag tshuaj uas muaj zog alkalis thiab chlorides tsis suav nrog.
Kev kho cua sov, vuam thiab nto tiav
1050 yog ib qho uas tsis yog- cua sov- kho tau alloy. Nws tus mob yog teem los ntawm kev ua hauj lwm txias thiab los ntawm annealing, thiab tsis muaj kev daws teeb meem thiab kev laus txheej txheem uas yuav txhawb nqa nws lub zog. Annealing tsuas yog siv los kho ductility thiab formability.
Daim ntawv qhia tag nrho:Thaum tshav kub kub rau 390-430 C, tuav rau 30 mus rau 120 feeb raws li zoo tuab, txias rau 300 C ntawm 30 mus rau 50 C ib teev, ces cua txias.
Rapid anneal:Kub rau 350-370 C, tuav rau 30 mus rau 120 feeb, ces txias hauv huab cua lossis dej.
Kev ntxhov siab:Kev kho kub tsis tshua muaj siv nyob nruab nrab ntawm cov theem ua haujlwm txias kom rov qab ductility ua ntej yuav txo qis ntxiv.
Vuam cwj pwm yog qhov zoo. Gas tungsten arc (TIG) thiab roj hlau arc (MIG) cov txheej txheem yog ob qho tib si siv, thiab cov hlau kuj tseem haum rau cov roj vuam, hydrogen atom welding thiab tsis kam vuam, txawm hais tias brazing nyuaj vim cov oxide zaj duab xis yog ib qho nyuaj rau tshem tawm. Cov kev xaiv saum npoo av muaj xws li anodising, electrophoretic txheej thiab pleev xim, tag nrho cov uas ua rau corrosion kuj thiab zoo li zoo rau architectural, neeg siv khoom electronics thiab sab hauv daim ntawv thov.

Cov lus nug nquag
Q: Puas tuaj yeem 1050 aluminium alloy muaj zog los ntawm kev kho cua sov?
Tsis yog. 1050 tsis yog- cua sov- qib kho tau, yog li lub zog tsuas yog nce los ntawm kev ua haujlwm txias thiab txo qis los ntawm kev sib tsoo. Kev kho mob thiab kev laus kev laus tsis muaj zog ntxiv rau qhov muaj pes tsawg leeg.
Q: Dab tsi yog qhov 99.5 feem pua cov ntsiab lus txhuas txhais tau tias hauv kev xyaum?
Nws txhais tau tias daim ntawv coj mus ze rau cov ntshiab aluminium: conductivity nyob twj ywm nyob rau hauv 61 mus rau 63 feem pua IACS ntau yam, corrosion kuj nyob twj ywm siab, thiab formability tseem zoo heev, thaum lub zog nyob qis qis.
Q: Puas yog 1050 zoo ib yam li 1050A?
Lawv muaj feem cuam tshuam txog kev lag luam purity qib nrog cov kev txwv zoo sib xws, thiab ob qho tib si raug pauv raws li 1050 daim ntawv. Qhov kev txwv qhov tseeb yuav tsum tau coj los ntawm tus qauv siv tau rau daim ntawv xaj khoom.
Q: Dab tsi tempers feem ntau muab?
O (annealed), F (raws li fabricated), H111 thiab H112 yog cov khoom siv niaj hnub rau cov ntawv thiab phaj. Temper xaiv yog tsav los ntawm tus nqi ntawm kev tsim ib feem yuav tsum muaj sia nyob thiab los ntawm lub zog ntawm qhov tiav qhov xav tau.
Q: Vim li cas 1050 nyiam rau qhov sib sib zog nqus nqus?
elongation ntawm 30 mus rau 50 feem pua ntawm cov mob annealed cia daim ntawv stretch deb ua ntej nws tawg, yog li sib sib zog nqus kos thiab spun duab tuaj yeem tsim yam tsis muaj qhov nruab nrab annealing ntawm ntau geometries.
Q: Ua li cas 1050 piv nrog 1060 rau kev ua haujlwm hluav taws xob?
Ob leeg yog cov qib purity kev lag luam nrog kev ua haujlwm siab . 1060 muaj ib qho kev lees paub ntau dua ntawm cov ntsiab lus txhuas thiab cov khoom siv hluav taws xob ntau dua, thaum 1050 muaj cov khoom siv dav dua thiab feem ntau yog qhov kev xaiv pheej yig dua thaum lub hom phiaj ua tau raws li qhov xav tau.
