Cov lus qhia no suav nrog 6061 aircraft aluminium ntawv tiag tiag, cov qauv uas tswj hwm nws, cov khoom muaj txiaj ntsig koj tuaj yeem xav tau, thiab kev sib piv ncaj ncees nrog 2024 thiab 7075.
Ntsiab Cai
- 6061 yog cov cua sov- kho tau Al-Mg-Si alloy sau npe los ntawm Lub Koom Haum Aluminium thiab muab rau ASTM B209 lossis SAE AMS 4027.
- Yam tsawg kawg nkaus rau 6061-T6 daim ntawv rau ASTM B209: 290 MPa (42 ksi) qhov kawg tensile, 241 MPa (35 ksi) yield, 8% elongation hauv 50 mm; Tus nqi raug yog li ntawm 310 MPa thiab 276 MPa.
- Qhov ceev yog 2.70 g / cm³, txog ib -peb ntawm cov hlau, uas yog vim li cas 6061 nyiam nyob qhov twg qhov hnyav tseem ceeb.
- 6061 welds thiab anodizes zoo; 2024 thiab 7075 tsis welded yooj yim - lub ntsiab yog vim li cas 6061 tshwm nyob rau hauv aircraft fittings, pem teb, qhov rooj thiab sab hauv tsev.
- "Aircraft grade" rau 6061 txhais tau hais tias tsim nyog rau cov qauv dav hlau thib ob thiab sab hauv, tsis yog thawj qhov kev thauj khoom -cov kabmob airframe tawv (feem ntau yog 2xxx/7xxx alloys).
Dab tsi yog6061 Aircraft Aluminium Sheet?
6061 yog ib qho txhuas alloy uas nws lub ntsiab ntxiv yog magnesium (0.80-1.20%) thiab silicon (0.40-0.80%), nrog tooj liab thiab chromium ntxiv los txhim kho lub zog thiab kev coj tus cwj pwm. Vim tias nws yog cua sov- kho tau, nws lub zog tuaj yeem tsa tau zoo tshaj qhov kev mob annealed los ntawm kev kho cua sov ua raws li kev laus laus - T6 temper.
Nyob rau hauv daim ntawv thiab phaj daim ntawv nws yog cais los ntawm tib thickness ciam teb siv nyob rau hauv ASTM B209: daim ntawv ntawm 0.15 hli mus rau 6.3 hli (0.006–0.249 nyob rau hauv) thiab phaj ntawm 6.35 hli (0.250 nyob rau hauv) upward. Cov neeg muag khoom siv daim ntawv lo "aircraft" vim 6061 yog cov khoom siv dav hlau lees paub (AMS 4027) thiab vim tias nws tau raug ntsia rau hauv dav hlau tiag tiag - tab sis qhov tseeb ntawm kev siv yog cov qauv theem nrab, sab hauv, fittings thiab tsis yog - qhov tseem ceeb, raws li cov lus qhia hauv qab no.
Chemical Composition (Raws li ASTM B209 / AA Kev Sau Npe)
Cov kev txwv muaj xws li hauv qab no yog cov nqi sau npe rau alloy 6061 (Lub Koom Haum Aluminium, International Alloy Designations thiab Chemical Composition Limits; luam tawm hauv ASTM B209, EN 573-3 thiab ISO 209). Qhov sib npaug yog aluminium.
