GR5 Titanium Alloy (Ti-6Al-4V): Muaj pes tsawg leeg, khoom, thiab kev siv
Jan 20, 2026
GR5 Titanium Alloy yog dab tsi?
GR5 titanium alloy, tsim Ti-6Al-4V, yog alpha-beta ob-theem titanium alloy. Aluminium ua raws li alpha stabilizer uas ua rau kom muaj zog thiab kub tsis kam, thaum vanadium ua raws li beta stabilizer uas txhim kho ductility thiab toughness. Cov ntsiab lus impurity xws li hlau, oxygen, nitrogen, carbon, thiab hydrogen yog tswj nruj me ntsis kom lav qhov kev ua haujlwm zoo ib yam.
Tshuaj muaj pes tsawg leeg
| Element | Cov ntsiab lus (wt.%) |
|---|---|
| Titanium | Tshuav |
| Aluminium | 5.5 - 6.75 |
| Vanadium | 3.5 - 4.5 |
| Hlau | 0.40 max |
| Oxygen | 0.20 max |
| Cov pa roj carbon | 0.08 max |
| Nitrogen | 0.05 max |
| Hydrogen | 0.015 max |
Lub cev muaj zog
Qhov ceev: kwv yees li 4.43 g / cm3, me ntsis qis dua li kev lag luam ntshiab titanium ntawm 4.51 g / cm3.
Melting point: kwv yees li 1650 degrees Celsius, haum rau siab -kev siv kub.
Cov khoom sib nqus: tag nrho tsis yog{0}} sib nqus, uas tshem tawm cov kev cuam tshuam sib nqus hauv cov cuab yeej siv dav hlau thiab cov khoom siv kho mob.
Mechanical Properties
Nyob rau hauv cov xwm txheej annealed ib ASTM B265, GR5 muab lub zog tensile yam tsawg kawg nkaus ntawm 895 MPa thiab qhov tsawg kawg nkaus yield zog ntawm 828 MPa. Hom annealed tensile lub zog yog li ntawm 895 txog 1000 MPa nyob ntawm seb qhov loj me thiab keeb kwm ua haujlwm. Elongation yog 10 feem pua tsawg kawg, thiab cov hlau tseem khaws cia zoo toughness mus rau qhov kub thiab txias. Nws nthuav tawm kev ua haujlwm qaug zog zoo nyob rau hauv siab - zaus hloov pauv thiab muaj zog nkag siab hauv kev pabcuam hauv qab li ntawm 400 degrees Celsius.
Corrosion Resistance
GR5 tsim cov khoom ntom ntom, tus kheej- kho oxide zaj duab xis uas muab kev tiv thaiv zoo hauv huab cua, dej hiav txwv, thiab ntau cov kua qaub thiab alkaline xov xwm. Nws tiv taus cov tshuaj chloride-induced pitting thiab kev ntxhov siab corrosion cracking zoo dua li feem ntau stainless hlau, uas yog vim li cas nws yog dav siv nyob rau hauv marine engineering thiab tshuaj ua khoom siv.
Daim ntawv thov teb
Aerospace
GR5 yog siv rau lub dav hlau cav Cheebtsam, airframe lug, tsaws iav qhov chaw, thiab fasteners, qhov twg lub zog - mus rau - luj piv ncaj qha txhim kho payload thiab roj efficiency.
Kho mob
GR5 yog siv rau cov cuab yeej phais thiab thauj khoom -cov kabmob cog. Rau kev cog qoob loo mus tas li, ELI hloov pauv Qib 23 rau ASTM F136 yog qhov zoo dua rau nws qhov hnyav dua thiab biocompatibility.
Automotive thiab Motorsport
Cov pa hluav taws xob, cov khoom siv hluav taws xob, thiab cov fasteners ua los ntawm GR5 txo qhov tsis muaj zog thiab txhim kho kev ua haujlwm thiab kev lag luam roj.
Marine thiab Tshuaj Kev Lag Luam
Seawater desalination khoom, offshore platforms, corrosion-resistant piping, li qub, thiab cia tso tsheb hlau luam tau txais txiaj ntsig los ntawm cov hlau tsis kam rau dej hiav txwv thiab tshuaj lom neeg.
Khoom siv ncaws pob
Cov tsheb kauj vab, lub taub hau golf, thiab ntaus pob tesniv siv GR5 rau nws qhov sib xyaw ua ke ntawm lub teeb yuag, lub zog, thiab kav ntev.
Cov lus nug nquag
Puas yog GR5 tib yam li Ti-6Al-4V?
Yog lawm. GR5 yog Suav qib tsim rau cov hlau uas paub thoob ntiaj teb li Ti-6Al-4V thiab raws li titanium Qib 5 hauv ASTM system.
Dab tsi yog qhov ceev ntawm GR5 titanium alloy?
Qhov ceev yog kwv yees li 4.43 g / cm3, kwv yees li 56 feem pua ntawm cov carbon hlau.
GR5 titanium puas tuaj yeem welded?
Yog lawm, GR5 tuaj yeem txuas nrog TIG, MIG, plasma, thiab electron beam txheej txheem, yog tias qhov sib koom ua ke muaj kev tiv thaiv siab -purity argon shielding.
Puas yog GR5 haum rau kev cog qoob loo?
GR5 yog siv rau cov cuab yeej phais, tab sis rau kev cog qoob loo mus tas li qhov sib txawv ntawm qhov sib txawv ntawm Ti-6Al-4V ELI, lossis Qib 23, tau teev tseg kom tau raws li ASTM F136.
Qhov kev pabcuam siab tshaj plaws ntawm GR5 yog dab tsi?
GR5 feem ntau yog ntsuas rau kev pabcuam txuas ntxiv mus txog kwv yees li 400 degrees Celsius, saum toj no uas nkag siab thiab oxidation tus cwj pwm yuav tsum tau tshuaj xyuas rau daim ntawv thov tshwj xeeb.
GR5 piv nrog kev lag luam ntshiab titanium li cas?
GR5 muaj kwv yees li ob zaug lub zog ntawm cov qib ntshiab titanium nrog kev txo me me hauv kev tsim thiab weldability, uas ua rau nws qhov kev xaiv zoo tshaj plaws rau kev thauj khoom -cov ntaub ntawv siv cov qauv.
