GR5 Titanium Alloy (Ti-6Al-4V): Daim ntawv thov Scope thiab Key Properties
Jan 20, 2026
GR5 titanium alloy, tsim TC4 hauv Suav teb thiab Ti-6Al-4V thoob ntiaj teb, yog cov khoom siv ntawm kev lag luam titanium. Thaum cov engineers qhia titanium yam tsis muaj qib tshwj xeeb hauv siab, lawv feem ntau txhais tau tias qhov no alpha-beta alloy, uas sib txuas lub zog tensile siab tshaj 895 MPa nrog qhov ceev ntawm 4.43 g / cm³. Nws qhov kev nthuav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav, chaw tsim khoom lag luam thoob ntiaj teb, chaw tsim khoom, chaw tsim khoom, Hoobkas, lag luam wholesale
Kev sib xyaw thiab kev faib tawm
GR5 muaj 5.5-6.75% txhuas thiab 3.5-4.5% vanadium ib ASTM B265, nrog hlau txwv rau 0.40%, oxygen rau 0.20%, thiab hydrogen rau 0.015%. Aluminium stabilizes lub hexagonal alpha theem, tsa lub zog thiab creep tsis kam; vanadium stabilizes lub cev-centered cubic beta theem, txhim kho ductility thiab toughness. Tus qauv dual-theem, tsim los ntawm kev ua haujlwm hauv qab ntawm beta transus ntawm txog 995 degree, muab cov alloy nws cov khoom sib npaug.
Cov khoom tseem ceeb ntawm GR5 Titanium Alloy
1. Tsawg ceev thiab muaj zog tshwj xeeb
Qib 5 qhov ceev yog 4.43 g / cm³, li 44% sib zog dua hlau. Nws lub zog-rau- qhov sib piv ceev tshaj qhov feem ntau ntawm cov qauv hlau thiab txhuas alloys, uas yog vim li cas nws thiaj li dominates airframe thiab cav siv.
2. Corrosion Resistance
Zoo li txhua yam titanium alloys, GR5 tso siab rau qhov ntom ntom, tus kheej - kho oxide zaj duab xis rau kev tiv thaiv. Nws tiv taus dej hiav txwv, chlorides, oxidizing acids, thiab feem ntau cov organic media. Cov zaj duab xis regenerates nyob rau hauv milliseconds yog mechanically puas, uas yog vim li cas titanium khoom nyob rau hauv marine thiab tshuaj siv nyob rau hauv lub xyoo caum. Rau qhov kub txo cov kua qaub los yog cov kab mob loj heev, palladium-cov qhab nia xws li Qib 7 lossis Qib 12 yog nyiam tshaj GR5.
3. Zoo siab -Tub kub muaj zog
GR5 khaws cia lub zog muaj txiaj ntsig ntawm 300-400 degree, zoo tshaj lub qab nthab rau aluminium alloys, thiab tuaj yeem ua haujlwm luv luv -lub sij hawm peaks mus txog 500℃hauv qhov tsis yog{6}} ntu tseem ceeb. Ntev -lub sij hawm creep kev pab cuam saum 400℃hu rau ze-alpha alloys xws li Ti-6Al-2Sn-4Zr-2Mo.
4. Tsawg-Tsub Toughness
Lub zog nce thaum kub poob thaum ductility yog tswj. GR5 thiab nws cov ELI variant tseem tawv ntawm qhov kub thiab txias mus rau -253 degree, ua rau lawv cov khoom xaiv rau cov hlab ntsha cryogenic thiab cov khoom siv roj liquefied.
5. Siab qaug zog
Qhov zoo equiaxed microstructure tsim los ntawm kev tswj cov thermomechanical ua muab GR5 zoo heev qaug zog tiv thaiv nyob rau hauv cyclic loading, ib tug txiav txim zoo nyob rau hauv rotating aircraft thiab automotive Cheebtsam.
6. Tsis yog-Magnetic thiab Biocompatible
GR5 tsis yog-sib nqus, uas tseem ceeb hauv MRI ib puag ncig thiab kev tswj xyuas lub nkoj sib nqus kos npe. Nws biocompatibility, nrog rau kev kho saum npoo kom txwv ion tso tawm, txhawb nqa nws siv hauv orthopedic thiab kho hniav implants ib ISO 5832-3 thiab ASTM F136.
7. High Yield Ratio
Tensile thiab yield zog yog nyob ze, uas txhais tau hais tias txwv yas deformation ua ntej tsis ua hauj lwm thiab tseem ceeb springback nyob rau hauv txoj kev. Tooling yuav tsum suav rau qhov no, thiab kub sib sau yog siv rau complex duab.
8. Kev hloov pauv cua sov
Txawm hais tias titanium ua cua sov tsis zoo, kwv yees li 7 W / m·K, nyias- phab ntsa GR5 cov khoom siv hluav taws xob hloov pauv los ntawm kev txo cov phab ntsa tuab thiab tsis yog - qhov chaw scaling, xa cov khoom siv hluav taws xob hloov pauv hauv kev ua haujlwm corrosive.
9. Tsawg Elastic Modulus
Thaum txog 110 GPa, lub modulus yog kwv yees li 57% ntawm cov hlau. Qhov no txo qis qhov tawv tawv tab sis txhim kho qhov qaug zog tus cwj pwm ntawm cov springs thiab saj zawg zog Cheebtsam, thiab nws txo qhov kev ntxhov siab -shielding nyhuv nyob rau hauv cov pob txha cog.
10. Gas Absorption ntawm Kub Kub
Tshaj li ntawm 400 degree, titanium reacts nrog oxygen, nitrogen, thiab hydrogen, tsim ib txheej txheej hardened. Tus cwj pwm no yog tswj hwm hauv kev ua haujlwm los ntawm lub tshuab nqus tsev lossis inert cua thiab tshem tawm los ntawm pickling tom qab ua haujlwm kub.

FAQ
TC4 txhais li cas?
TC4 yog Suav lub npe rau Ti-6Al-4V nyob rau hauv GB / T 3620.1: T qhia titanium alloy, C qhia alpha-beta hom, thiab 4 yog tus lej xov tooj. Nws yog sib npaug rau ASTM Qib 5.
Puas yog GR5 titanium muaj zog dua hlau?
Hauv cov ntsiab lus tshwj xeeb muaj zog, yog. GR5 tensile lub zog yog piv rau nruab nrab - lub zog steels ntawm li 60% ntawm qhov hnyav, uas yog vim li cas nws hloov cov hlau hauv qhov hnyav - cov qauv tseem ceeb.
GR5 puas tuaj yeem ua anodized?
Yog lawm. Anodizing loj hlob oxide zaj duab xis tuab rau kev tiv thaiv corrosion, hnav tsis kam, lossis xim xim. Nws tsis hloov lub hauv paus mechanical zog.
Puas yog GR5 corrode hauv dej hiav txwv?
Tsis yog. Nws tus kheej - kho oxide zaj duab xis muab cov dej hiav txwv zoo heev. Pitting thiab crevice nres tsuas yog muaj kev pheej hmoo ntawm qhov nruj nruj ntawm qhov kub siab, qhov twg Qib 7 lossis Qib 12 nyiam dua.
Qhov siab tshaj plaws ua haujlwm kub ntawm GR5 yog dab tsi?
Kev pabcuam txuas ntxiv feem ntau txwv rau 300-400℃. Tshaj 400 degree, oxidation thiab creep txo lub neej; siab - kub nyob ze-alpha alloys tau teev tseg rau 500-600℃kev pabcuam.
Vim li cas GR5 siv rau kev cog hniav kho mob?
Nws ua ke lub zog siab, kev tiv thaiv corrosion, tsis yog - tshuaj lom, thiab pob txha- tau tshaj modulus. Rau lub sijhawm ntev - cog qoob loo, ELI qhov sib txawv ntawm ASTM F136 nrog cov pa oxygen tsawg tau teev tseg kom ua kom cov pob txha pob txha loj tshaj.
