Qhov txawv ntawm TC4 titanium alloy screws thiab GR5 titanium alloy screws yog dab tsi?
Kev Txheeb Xyuas Sai ntawm TC4 thiab GR5 Titanium Alloy Screws
TC4 = GR5; cov khoom siv yog tib yam nkaus - ob qho tib si yog Ti-6Al-4V (titanium 6, txhuas 4, vanadium 4) - tab sis lawv tsuas yog cov npe sib txawv nyob rau hauv ob lub txheej txheem txheem sib txawv.
TC4: GB/T (Suav Teb Chaws Tus Qauv) qib, siv rau hauv cov duab kos hauv tsev, cov ntawv ceeb toom kev tshuaj xyuas zoo hauv tsev, thiab cov haujlwm hauv tsev.
GR5 (Qib 5): ASTM (American Standard) qib, siv rau kev lag luam xa tawm, kos duab los ntawm cov neeg siv khoom txawv teb chaws, thiab kev yuav khoom los ntawm Tebchaws Europe thiab Tebchaws Meskas.
I. Cov Khoom Siv
Cov khoom xyaw: Ti-6Al-4V
Qhov Ceev: 4.51 g/cm³, kwv yees li 45% sib dua hlau
Lub Zog Tensile: ≥895 MPa; Lub Zog Tawm: ≥825 MPa
Hardness: HV 320–380 (annealed mob); muaj zog heev, tsis muaj hlau nplaum, tiv taus ntsev tsuag, thiab tsis xeb
Cov Ntawv Thov: Cov khoom siv txuas rau tsheb kauj vab, maus taus, kev hloov kho tsheb, thiab kev siv dav hlau - suav nrog cov ntsia hlau sab hauv lub hnub qub, cov txiv ntoo flange, thiab cov ntsia hlau log hub
II. Tsuas Yog Qhov Txawv Uas Siv Tau
Daim Ntawv Pov Thawj Khoom Siv
TC4 ntsia hlau: Los nrog daim ntawv pov thawj khoom siv GB / T (Suav Tebchaws Txuj Ci).
GR5 ntsia hlau: Los nrog daim ntawv pov thawj ASTM B348 (Tebchaws Meskas Tus Qauv), tsim nyog rau kev tshem tawm kev lis kev cai xa tawm thiab kev tshuaj xyuas Hoobkas los ntawm cov neeg siv khoom txawv teb chaws.
Cov Lus Cim Kos Duab: Cov duab kos hauv tebchaws qhia meej tias "TC4"; cov duab kos xa tawm qhia meej tias "GR5" (Qib 5). Tsis muaj qhov sib txawv ntawm cov khoom siv raw, kev siv tshuab, kev kho cua sov, lossis cov khoom siv kho tshuab ntawm cov khoom tiav.
Ceeb Toom Txog Kev Phom Sij Hauv Kev Lag Luam: Muaj ob peb tus neeg muag khoom tsis muaj kev ncaj ncees uas yuav ua rau muaj kev tsis meej pem: GR5 ≠ GR2 (titanium ntshiab TA2); GR2 yog titanium ntshiab uas muaj zog qis dua. Tsis txhob yuav titanium ntshiab zoo li nws yog GR5 titanium alloy. Ntxiv mus: TC4 ELI = GR23 (qib kho mob qis heev; qhov no tsis yog tib pawg li tus qauv TC4/GR5 thiab yuav tsum tsis txhob siv hloov pauv).
| Khoom | TC4 Titanium Alloy Screws | GR5 Titanium Alloy Screws |
| Cov Khoom Siv Sib xyaw | Ti-6Al-4V | Ti-6Al-4V |
| Txheej Txheem Txheem | Tuam Tshoj GB/T | Tebchaws Meskas ASTM B348 |
| Cov Khoom Siv Kho Tshuab | Lub zog tensile ≥ 895 MPa | Lub zog tensile ≥ 895 MPa |
| Cov Ntawv Thov Cov Tshuab Siv Hauv Tsev | kev hloov kho maus taus/tsheb kauj vab, kev tsav dav hlau | Kev xa khoom mus rau txawv teb chaws, kev xa khoom mus rau txawv teb chaws, kev txiav txim thoob ntiaj teb |
| Qhov Hnyav / Kev Tiv Thaiv Xeb | Sib xws | Sib xws |
III. Cov Lus Qhia Txog Kev Xaiv
✅ Kev muag khoom hauv tebchaws thiab cov haujlwm hauv tebchaws: Qhia meej TC4 ✅ Kev xa tawm txawv teb chaws, cov neeg siv khoom txawv teb chaws, thiab cov duab kos European/Tebchaws Meskas: Qhia meej GR5 (Qib 5)
Rau cov pas nrig titanium los ntawm tib pawg, cov ntawv qhia kev xeem hauv tsev tuaj yeem muab rau TC4, thiab daim ntawv pov thawj khoom siv txheem hauv Tebchaws Meskas tuaj yeem muab rau GR5, tsis muaj kev hloov pauv hauv kev ua haujlwm ntawm cov ntsia hlau lawv tus kheej.
