3003 Aluminium yog dab tsi?
3003 txhuas belongs rau 3xxx series, lub ntsiab lus nws yog alloyed feem ntau nrog manganese. Nws muaj ntau lub zog ntau dua li kev lag luam ntshiab 1000 series txhuas thaum tuav tshwj xeeb tsis kam rau atmospheric thiab tshuaj corrosion. Qhov tseem ceeb tshaj plaws uas yuav tsum nco ntsoov yog tias 3003 yog ib qho uas tsis yog - tshav kub- kho tau alloy: nws lub zog tsis tuaj yeem nce los ntawm nag lossis daus hardening hauv lub cub tawg. Lub zog yog tsim los ntawm cov neeg kho tshuab txias ua haujlwm, yog li lub temper designation tag nrho cov khoom coj tus cwj pwm rau ib daim ntawv thov.
H18 vs O: Qhov txawv ntawm Core
H18 npau taws qhia tias muaj mob hnyav. Cov txhuas yog txias- dov tsis tu ncua kom txog thaum nws nce mus txog qhov txo qis kev lag luam, tsis muaj cua sov siv los ua kom nws. Cov txheej txheem sab hauv yog qhov hnyav heev, muab lub zog siab tshaj plaws thiab qhov nyuaj ua tau rau 3003 alloy, tab sis tawm hauv yuav luag tsis muaj peev xwm ncab. O temper qhia tau hais tias muaj kev mob siab rau tag nrho. Tom qab dov, cov hlau yog rhuab nyob rau hauv ib lub qhov cub rau ib tug tshwj xeeb recrystallization kub, uas erases lub internal kev nyuaj siab thiab strain hardening tsim thaum dov. Qhov tshwm sim yog qhov softest, feem ntau ductile xeev ua tau rau 3003. Nyob rau hauv cov ntsiab lus, O muaj zoo heev formability nrog tsawg zog, thaum H18 muaj siab tshaj plaws rigidity nrog tsawg ductility.
Mechanical Properties Sib piv
Rau cov engineers xam cov cuab yeej siab, nias nres tonnage, thiab tuag clearances, cov nqi luam tawm ib txwm rau daim ntawv yog lub tswv yim pib. Rau 3003 O, lub zog tensile ib txwm yog li 95 txog 130 MPa, tawm lub zog txog 30 txog 50 MPa, hardness txog 20 txog 30 HB, thiab elongation feem ntau siab dua 20 feem pua. Rau 3003 H18, lub zog tensile ib txwm yog li 185 txog 215 MPa nyob ntawm qhov ntsuas, tawm lub zog txog 165 txog 200 MPa, hardness txog 40 txog 55 HB, thiab elongation tsuas yog li 2 mus rau 4 feem pua. Qhov kev sib piv ntawm lub zog sib piv piav qhia qhov sib txawv ntawm qhov ua tau zoo: H18 yuav tsum muaj kwv yees li peb mus rau plaub zaug ntau zog kom deform mus tas li tshaj O. Elongation yog qhov txiav txim siab rau fabrication: O temper tuaj yeem ncav cuag qhov tuag, thaum H18 yuav tawg yog tias ncab. Paub meej tias qhov tseem ceeb ntawm daim ntawv pov thawj zeb xeem thiab cov txheej txheem tswj hwm xws li ASTM B209 lossis EN 485.
Manufacturing Mechanisms: Txias Rolling vs Annealing
Qhov sib txawv ntawm lub cev ntawm cov tempers no yog los ntawm lawv cov txheej txheem tsim khoom. Lub tshuab H18 yog cov neeg kho tshuab nkaus xwb: txias dov quab yuam cov siv lead ua lattice kom compress thiab cuam tshuam, tsim kom muaj qhov sib txawv ntawm qhov sib txawv uas ua rau cov hlau nyuaj thiab muaj zog. O temper mechanism yog thermally ntshiab: lub qhov cub annealing muab cov atoms txaus lub zog los tsim ib qho tshiab, kev nyuaj siab-dawb nplej qauv los ntawm recrystallization, so tawm cov teebmeem ntawm txias dov. Cov xeev no hloov pauv tau: H18 coil tuaj yeem ua rau O temper los ntawm lub voj voog tag nrho, thiab O daim ntawv yuav ua haujlwm ib txwm muaj- tawv thaum ua haujlwm xws li stamping lossis kos duab, yog li qhov tsim feem ntau xaus nrog lub zog ze rau H- temper.
Daim ntawv thov ntawm 3003 O vs 3003 H18
3003 O daim ntawv raug xaiv thaum muaj kev sib sau ua ke yog qhov tseem ceeb. Cov ntawv thov ib txwm muaj xws li sib sib zog nqus- kos cookware, pots, pans, thiab seamless ntim; Cov khoom siv tshuaj lom neeg nrog cov khoom tsim, spun funnels, thiab kev cai kav; spun hlau khoom xws li teeb ntxoov ntxoo, reflectors, thiab hniav vaj tse; thiab hloov tau yooj yim ntim raws li cov khoom siv rau hnyav foils thiab pliable tubes . 3003 H18 coil raug xaiv thaum qhov siab tshaj plaws rigidity nyob rau hauv ib tug nyias gauge yog yuav tsum tau thiab tsim yog tsis tsim nyog. Cov ntawv thov ib txwm muaj xws li lub kaus mom lub raj mis thiab kaw uas yuav tsum nyob twj ywm nruj hauv qab capping siab; cov ntawv vov tsev uas cia siab rau tag nrho- tawv tawv kom tiv taus cua thiab lawg denting; nruj tiaj ntim; thiab siab- hardness nyias daim ntawv xws li cov npe muaj npe, dials, thiab tiaj tus stamped qhov chaw.
Daim Ntawv Qhia Kev Xaiv Rau Kev Muag Khoom
Xaiv 3003 O thaum ua cov duab sib sib zog nqus, hlau spinning, los yog complex 3D stamping, thaum tus tsim xav kom cov hlau mus stretch ho tsis muaj tearing, thiab thaum lub zog ntawm cov qauv nyob rau hauv lub tiaj tus tsis yog lub hauv paus kev txhawj xeeb. Xaiv 3003 H18 thaum lub zog siab tshaj plaws thiab hardness rau cov hlau yuav tsum tau, thaum cov khoom tseem ceeb yog tiaj tus lossis tsim los ntawm siab - nrawm nrawm punching, thiab thaum hnyav hnyav hauv cov ntsuas nyias nyias yog xav tau yam tsis muaj kev khoov ntse. Nco ntsoov tias tsis muaj kev npau taws tuaj yeem ntxiv dag zog los ntawm kev kho cua sov; thov cov cua sov tsuas yog softens 3003. Yog tias cov khoom uas tuaj yeem tsim tau muag muag thiab tom qab ntawd yuav tsum tau ua kom tawv tawv hauv lub qhov cub, qhov cua sov- kho tau 6xxx alloy xws li 6061 yog qhov kev xaiv tsim nyog.
FAQ
Q: Qhov txawv ntawm 3003 H18 thiab O aluminium yog dab tsi?
A: Qhov txawv yog qhov kub ntxhov . 3003 H18 ua haujlwm tag nrho- tawv, ua rau nws muaj zog, tawv, thiab nkig, thaum 3003 O yog tag nrho annealed thiab kub- softened, ua rau nws ductile heev thiab yooj yim rau daim ntawv.
Q: Puas yog H18 muaj zog dua li O temper?
A: Yog. 3003 H18 muaj zog tensile thiab yield zog ntau dua li O temper, nrog lub zog tawm los feem ntau ntau dua, ntawm tus nqi qis heev elongation.
Q: Qhov twg yog qhov zoo dua rau kev tsim, O lossis H18?
A: 3003 O yog qhov zoo dua rau kev tsim. Nws lub xeev annealed tag nrho muab qhov siab tshaj plaws elongation xav tau rau kev sib sib zog nqus nqus, dabtsi yog khoov, thiab spinning, thaum H18 yog nquag tawg thaum tsim.
Q: H18 puas tuaj yeem hloov mus rau O temper?
A: Yog. Yog hais tias 3003 H18 txhuas yog annealed nyob rau hauv ib tug muaj rauv ntawm qhov tseeb recrystallization kub, nws softens kiag li thiab ua tus O temper.
Q: Vim li cas O temper softer dua H18?
A: Because the thermal annealing process relieves all internal mechanical stresses and creates a new, uncompressed grain structure, whereas H18 retains a dense dislocation structure from cold rolling.
