Gr3 titanium foil yob yog coiled unalloyed Qib 3 titanium ntawv ci hauv thicknesses ntawm 0.01 hli mus rau 0.20 hli. Qib 3 muaj cov pa oxygen ntau dua li Qib 1 thiab Qib 2, uas nce lub zog tensile mus rau qhov tsawg kawg nkaus ntawm 450 MPa thaum khaws cov khoom lag luam kom huv si thiab tsis yog -alloyed. Cov ntawv ci ua los ntawm Qib 3 yog siv qhov kev tiv thaiv corrosion ntawm titanium yuav tsum tau ua ke nrog kev nruj dua thiab muaj peev xwm thauj khoom ntau dua li cov qib softer tuaj yeem muab tau.
Qib 3 Titanium Foil yog dab tsi
Qib 3 titanium, tsim UNS R50550, yog ib qho alpha-theem unalloyed titanium uas nws cov ntsiab lus oxygen siab dua ua ib qho khoom ua kom muaj zog- kev daws teeb meem. Cov hlau nyob twj ywm muaj zog txaus rau kev ua kom txias thiab vuam, tab sis muaj kwv yees li 30% ntau tensile zog dua qib 2 thiab txog 88% ntau dua li Qib 1. Nws tseem tsis yog-sib nqus thiab ua rau tus kheej- kho cov zaj duab xis passive oxide uas tiv thaiv titanium hauv chlorides thiab oxidizing acids.

Qib 3 Piv nrog Qib 1 thiab Qib 2
Peb qib kev lag luam ntshiab sib koom ua ke tib lub tshuab corrosion tab sis txawv ntawm lub zog. Qib 1 yog qhov softest thiab feem ntau formable, Qib 2 yog qhov dav -lub hom phiaj workhorse, thiab Qib 3 muab lub zog siab tshaj plaws uas tseem tuaj yeem ua tiav yam tsis muaj alloying ntxiv. Qhov twg cov khoom yuav tsum nqa nqa, tiv thaiv deformation lossis tuav cov duab tom qab tsim tab sis yuav tsum tsis txhob siv qib titanium alloyed, Qib 3 ntawv ci yog qhov kev xaiv tsim nyog.
Daim ntawv thov ntawm Gr3 Titanium Foil Roll
Chemical processing gaskets, diaphragms thiab saj zawg zog seals uas yuav tsum tau tiv thaiv chlorides
Cov khoom siv kho mob thiab cov ntawv ntsuas ntsuas yuav tsum muaj lub zog siab hauv cov ntu nyias
Aerospace shims, spacers thiab lub teeb yuag structural foil sib dhos
Electrochemical electrodes thiab tam sim no collector ntawv ci nyob rau hauv corrosive electrolytes
Marine hardware thiab seawater- nthuav tawm cov khoom hloov tau yooj yim
Precision springs thiab tsim qhov chaw xav tau kev nruj dua li Qib 2 tso cai
Kev tsim, vuam thiab kev kho cua sov
Qib 3 foil txias cov ntaub ntawv zoo, txawm hais tias nws lub zog siab dua txhais tau tias me ntsis khoov radii loj dua thiab ntau dua springback dua qib 1 lossis Qib 2. Kev sib xyaw hauv lub tshuab nqus tsev lossis cov cua tsis zoo rov ua kom cov ductility tom qab hnyav tsim thiab tiv thaiv cov pa oxygen thiab hydrogen pickup. Vuam yog nqa tawm los ntawm tungsten inert gas los yog laser txheej txheem nrog tag nrho inert shielding, thiab cov tiav kev sib koom ua kom cov corrosion kuj ntawm niam txiv ntawv ci thaum lub tshav kub tint raug tshem tawm.
Cov lus nug nquag
Q: Dab tsi yog qhov txawv ntawm Qib 2 thiab Qib 3 titanium ntawv ci?
Qib 3 muaj cov pa ntau dua, muab lub zog tensile yam tsawg kawg nkaus ntawm 450 MPa tiv thaiv 345 MPa rau Qib 2, thiab qhov tsawg kawg nkaus tawm lub zog ntawm 380 MPa tawm tsam 275 MPa.
Q: Cov qauv twg npog Gr3 titanium ntawv yob?
ASTM B265 thiab ASME SB265 npog unalloyed titanium sawb, daim ntawv thiab phaj, thaum ASTM F67 qhia txog unalloyed titanium qib rau kev phais phais siv.
Q: Puas yog Qib 3 daim ntawv tseem tiv taus corrosion?
Yog lawm. Qib 3 yog unalloyed titanium, yog li nws khaws cov passive oxide zaj duab xis uas tiv thaiv titanium hauv dej hiav txwv, chloride brines thiab oxidizing acids.
Q: Qib 3 ntawv ci tuaj yeem sib sib zog nqus?
Nws tsim tau yooj yim nyob rau hauv cov mob annealed, tab sis khoov radii yuav tsum loj dua thiab springback compensated nyob rau hauv cov cuab yeej vim Qib 3 muaj zog thiab tsawg dua ductile tshaj Qib 2.
Q: Yuav ua li cas yog foil nto xa?
Cov ntawv ci yog muab polished los yog pickled, txawm tias ci los yog nrog cov xim grey tag nrho ntawm cov tshuaj ntxuav tsis tau titanium.
Q: Yuav ua li cas yob ntim rau export?
Rolls yog qhov txhab ntawm cov cores, qhwv nrog kev tiv thaiv noo noo thiab ntim rau hauv cov rooj ntoo ntoo kom cov npoo thiab qhov chaw tuaj txog tsis muaj kev puas tsuaj.
