6061-T6 yog dab tsi?
6061-T6 yog ib tug temper designation xa mus rau 6061 txhuas uas tau raug mus rau ib tug nruj kev kho cua sov txheej txheem. T6 temper xav tau kev kho cua sov ua raws li kev laus laus. Thaum lub sij hawm kho cua sov theem, aluminium yog rhuab mus txog495 ° F (925 ° F)thiab ces quenched sai sai nyob rau hauv dej, dissolving alloying ntsiab xws li magnesium thiab silicon thiab tsim ib tug supersaturated khoom tov.
Tom qab ntawd cov khoom yog artificially hnub nyoog ntawm120-180 ° F (250-360 ° F)rau kwv yees li yim teev. Cov kauj ruam kev laus no precipitates cov ntsiab lus alloying, txhim kho cov hlau ua haujlwm zoo. Cov khoom ua tau zoo heev tensile zog, tawm los lub zog, thiab hardness. Txawm li cas los xij, thaum T6 muaj lub zog siab, nws kuj tseem tuaj yeem khaws cov kev ntxhov siab uas tau qhia thaum kho cua sov.
Cov txiaj ntsig ntawm 6061-T6 Aluminium
Siab zog:Muab lub zog tensile ntawm ib ncig310 MPa (45 ksi)thiab lub zog tawm los ntawm kwv yees li276 MPa (40 ksi), ua kom haum rau kev siv cov qauv siv.
Corrosion Resistance:Muab cov khoom tiv thaiv rau qhov hnyav ib puag ncig.
Weldability:Pom zoo weldability, txawm tias preheating tuaj yeem pab txo qhov tawg.
Versatility:Dav siv nyob rau hauv automotive Cheebtsam, marine qhov chaw, thiab aerospace lug.
6061-T651 yog dab tsi?
6061-T651 yog lwm tus npau taws ntawm tib lub alloy tab sis suav nrog cov txheej txheem ntxiv uas txhim kho kev ua haujlwm. Zoo li T6, T651 yog cov tshuaj kho cua sov thiab cov hnub nyoog tsim khoom.
Qhov sib txawv tseem ceeb yog qhovntxiv stretching lossis straightening kauj ruam tom qab laus, uas relieves residual stresses. Qhov kev ua haujlwm ntxiv no txhim kho qhov ruaj khov thiab tiaj tus, txo qis kev cuam tshuam los yog warping thaum lub sijhawm machining. Yog li ntawd, T651 tau txais kev pom zoo rau cov ntawv thov uas xav tau qhov ntev thiab qhov ntev.
Cov txiaj ntsig ntawm 6061-T651 Aluminium
Txhim kho Dimensional Stability:Txo qhov seem kev ntxhov siab ua kom muaj kev ruaj ntseg zoo dua thaum lub tshuab ua haujlwm.
Zoo dua Machinability:Tsawg sab hauv kev ntxhov siab tso cai yooj yim txiav thiab shaping yam tsis muaj deformation.
Tight Tolerances:Zoo tagnrho rau siab - precision aerospace qhov chaw thiab complex machined Cheebtsam.
Sib piv Lub Zog:Ua kom zoo sib xws tensile thiab tawm los lub zog rau T6.
6061-T6 vs . 6061-T651: Qhov txawv tseem ceeb
| Qhov xwm txheej | 6061-T6 | 6061-T651 |
