Lub cev muaj zog ntawm 6061 Aluminium

Hom 6061 txhuas yog ntawm 6xxx txhuas alloys, uas entails cov mixs uas siv magnesium thiab silicon ua thawj alloying ntsiab.Tus lej thib ob qhia txog qib ntawm impurity tswj rau lub hauv paus txhuas.Thaum tus lej thib ob no yog "0", nws qhia tau tias feem ntau ntawm cov hlau yog cov khoom lag luam txhuas uas muaj nws cov qib impurity uas twb muaj lawm, thiab tsis tas yuav muaj kev saib xyuas tshwj xeeb kom nruj tswj.Tus lej thib peb thiab tus lej thib plaub tsuas yog tus tsim qauv rau tus kheej cov alloys (nco ntsoov tias qhov no tsis yog nrog 1xxx aluminium alloys).Cov nominal muaj pes tsawg leeg ntawm hom 6061 txhuas yog 97.9% Al, 0.6% Si, 1.0% Mg, 0.2% Cr, thiab 0.28% Cu.Qhov ntom ntawm 6061 aluminium alloy yog 2.7 g / cm3.6061 aluminium alloy yog cua sov kho, tsim tau yooj yim, weld-tau, thiab zoo ntawm kev tiv thaiv corrosion.

Mechanical Properties

Cov khoom siv kho tshuab ntawm 6061 aluminium alloy txawv raws li nws tau kho cua sov, lossis ua kom muaj zog siv cov txheej txheem tempering.Nws modulus ntawm elasticity yog 68.9 GPa (10,000 ksi) thiab nws shear modulus yog 26 GPa (3770 ksi).Cov txiaj ntsig no ntsuas cov alloy qhov tawv, los yog tsis kam rau deformation, koj tuaj yeem pom nyob rau hauv Table 1. Feem ntau, cov hlau no yooj yim koom nrog vuam thiab nkag tau yooj yim deforms rau hauv cov duab uas xav tau ntau yam, ua rau nws muaj ntau yam khoom siv.

Ob yam tseem ceeb thaum xav txog cov khoom siv kho tshuab yog lub zog tawm los thiab lub zog kawg.Lub zog tawm los piav txog qhov siab tshaj plaws ntawm kev ntxhov siab uas yuav tsum tau ua kom elastically deform hauv ib qho kev npaj thauj khoom (nruj, compression, twisting, thiab lwm yam).Qhov kawg lub zog, ntawm qhov tod tes, piav qhia txog qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus ua ntej tawg (ua rau yas, lossis kev deformation mus tas li).6061 aluminium alloy muaj lub zog tensile ntawm 276 MPa (40000 psi), thiab lub zog tensile kawg ntawm 310 MPa (45000 psi).Cov txiaj ntsig no tau sau tseg hauv Table 1.

Lub zog shear yog lub peev xwm ntawm cov khoom siv los tiv thaiv los ntawm kev tawm tsam ntawm lub dav hlau, ib yam li txiab txiav los ntawm daim ntawv.Tus nqi no yog qhov muaj txiaj ntsig zoo hauv kev siv torsional (shafts, tuav thiab lwm yam), qhov kev sib tw tuaj yeem ua rau muaj kev ntxhov siab ntawm cov khoom siv no.Lub zog shear ntawm 6061 aluminium alloy yog 207 MPa (30000 psi), thiab cov txiaj ntsig no tau sau tseg hauv Table 1.

Lub zog qaug zog yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev tawg nyob rau hauv cyclical loading, qhov twg ib tug me me loaded dua reparted rau cov khoom nyob rau hauv lub sij hawm.Tus nqi no muaj txiaj ntsig zoo rau cov ntawv thov uas ib feem yuav raug rov ua dua lub voj voog thauj khoom xws li tsheb axles lossis pistons.Lub zog qaug zog ntawm 6061 aluminium alloy yog 96.5 Mpa (14000 psi).Cov txiaj ntsig no tau sau tseg hauv Table 1.

Corrosion Resistance

Thaum raug huab cua lossis dej, 6061 aluminium alloy tsim ib txheej ntawm oxide uas ua rau nws tsis muaj zog nrog cov ntsiab lus uas muaj corrosive rau hauv qab hlau.Tus nqi ntawm corrosion kuj yog nyob ntawm atmospheric/aqueous tej yam kev mob;Txawm li cas los xij, nyob rau hauv qhov kub thiab txias, cov teebmeem corrosive feem ntau tsis pom zoo hauv huab cua / dej.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias vim yog tooj liab cov ntsiab lus ntawm 6061, nws yog me ntsis resistant rau corrosion dua lwm yam alloy (xws li5052 aluminium alloy, uas tsis muaj tooj liab).6061 yog tshwj xeeb tshaj yog zoo ntawm kev tiv thaiv corrosion los ntawm concentrated nitric acid nrog rau ammonia thiab ammonium hydroxide.

Daim ntawv thov ntawm Hom 6061 Aluminium

Hom 6061 txhuas yog ib qho ntawm feem ntau siv txhuas alloys.Nws lub peev xwm weld-muaj peev xwm thiab formability ua rau nws haum rau ntau yam kev siv hom phiaj.Nws lub zog siab thiab corrosion kuj qiv hom 6061 alloy tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev tsim vaj tsev, qauv, thiab kev siv lub tsheb.Nws cov npe ntawm kev siv yog tag nrho, tab sis qee qhov kev siv loj ntawm 6061 aluminium alloy suav nrog:

• Welded sib dhos
• Marine ntas
• Aircraft thiabtsheb ncej
• Cov khoom siv tshuaj
• Cov khoom siv hluav taws xob
