Thaum nws los txog rau txhuas rau aerospace, automotive, lossis kev siv cov qauv, engineers nquag sib cav ntawm 6061 T651 thiab 6061 T6. Qhov twg zoo dua? Kab lus no tshuaj xyuas lawv cov tshuab zoo, cov txheej txheem tsim khoom, thiab cov ntawv thov tsim nyog los pab koj txiav txim siab zoo tshaj plaws.
Cov ntsiab lus tseem ceeb:
✔ T651 muab kev ruaj ntseg zoo dua qub (kev ntxhov siab-relieved)
✔ T6 muaj zog dua me ntsis (raws li -quenched)
✔ T651 yog haum rau precision machining
✔ T6 tsis tshua kim rau kev siv dav dav.
1. Cov txheej txheem tsim khoom: Qhov sib txawv ntawm T6 thiab T651
6061 T6 Aluminium
Txheej txheem:Kev kho cua sov- kho raws li kev laus kev laus.
Yam ntxwv:
Lub zog pib siab dua
Muaj peev xwm khaws cov kev ntxhov siab seem
Ntau raug rau warping thaum lub sij hawm machining
6061 T651 Txhuas
Txheej txheem:Ib yam li T6, nrog rau kev ntxhov siab ntxiv -txo cov kauj ruam los ntawm kev ncab (1-3% deformation mus tas li).
Yam ntxwv:
Txhim khu flatness thiab dimensional stability
Txo kev pheej hmoo ntawm machining distortion
Ntau yam khoom siv kho tshuab
2. Mechanical Properties Comparison
| Khoom | 6061 T6 | 6061 T651 | Qhov txawv |
|---|---|---|---|
| Tensile zog | 310 MPa (45 ksi) | 290 MPa (42 ksi) | T6 ~ 7% muaj zog |
| Yield zog | 275 MPa (40 ksi) | 240 MPa (35 ksi) | T6 ~ 15% siab dua |
| Elongation | 10% | 8% | T6 ntau ductile |
| Hardness (Brinell) | 95 HB | 95 HB | Sib npaug |
| Kev qaug zog | 96 MPa (14 ksi) | 97 MPa (14 ksi) | Yuav luag zoo ib yam |
| Machineability | Zoo | Zoo heev | T651 tiv thaiv warping |
Nco tseg:T651 lub zog qis dua me ntsis los ntawm kev ntxhov siab- txo qis, tab sis nws muab kev ruaj ntseg zoo dua rau qhov tseeb - cov ntawv thov tseem ceeb.
3. Thaum xaiv T6 vs. T651
Xaiv 6061 T6 yog tias koj xav tau:
✅ Lub zog siab tshaj plaws - rau - tus nqi piv
✅ General fabrication (tsis yog -welding los yog dabtsi yog khoov)
✅ Me me warping yog txais
Cov ntawv thov raug:
Tsheb ncej
Marine Cheebtsam
Cov qauv kev txhawb nqa
Xaiv 6061 T651 Yog tias koj xav tau:
✅ Kev ua haujlwm ruaj khov thaum lub sijhawm ua haujlwm precision
✅ Daim ntawv thov yuav tsum nruj flatness
✅ Aerospace lossis tiv thaiv - qib cov khoom
Cov ntawv thov raug:
Aircraft fittings
Optical mounts
Siab - siab ntev CNC qhov chaw
4. Tiag -Kev Tshawb Fawb Ntiaj Teb
Teeb meem:Lub tuam txhab tsim drone siv 6061 T6 rau tis spars thiab pom 0.3 hli warping tom qab machining.
Kev daws:Hloov mus rau 6061 T651 - warping txo rau<0.05 mm.
Tus nqi cuam tshuam:T651 tus nqi ~ 12% ntau dua tab sis txuag $ 22k toj ib hlis hauv kev txo qis.
5. FAQs-Quick Engineer's Guide
Q: T651 puas tuaj yeem ua kom sov ntxiv- kho kom ua tiav T6 cov khoom?
A:Tsis yog. Cov txheej txheem ncab mus tas li hloov kho microstructure.
Q: Puas yog T651 kim dua T6?
A:Yog lawm, feem ntau 10–20% siab dua vim muaj kev ntxhov siab ntxiv - kauj ruam nyem.
Q: Qhov twg zoo dua rau vuam?
A:Ob qho tib si weld zoo ib yam, tab sis T651 yog qhov zoo dua yog tias tom qab -weld machining yuav tsum tau.
Q: Puas yog T651 hwm zoo?
A:Yog lawm, rau cov ntawv thov uas xav tau siab flatness lossis machining stability, xws li aerospace jigs.
6. Kev Lag Luam Cov Qauv Ua Raws Cai
Ob tempers ua raws li:
ASTM B 209 Cov khoom siv(Plate / Phaj)
TIAB SA 4027(Aerospace)
TS EN 485-2(Tebchaws Europe)
Daim ntawv pov thawj tswv yim:Ib txwm thov mill test reports (MTRs) los ntawm GNEE los xyuas qhov npau taws.
