Vim li cas Alloy Selection Matters ntawm 3 mm thiab 5 mm
Aluminium ntawv thiab phaj nyob rau hauv lub 3 hli mus rau 5 hli thickness ntau yog siv rau ib tug dav dav ntawm daim ntaub ntawv, los ntawm lub tshuab npog thiab tsheb flooring rau tso tsheb hlau luam, enclosures thiab aircraft Cheebtsam. Ntawm cov thicknesses cov khoom yog nyias txaus los tsim thiab txiav kev lag luam, tab sis muaj zog txaus los nqa khoom. Lub alloy thiab temper txiav txim siab seb qhov yuav tuav zoo li cas, tiv thaiv corrosion thiab weld reliably, yog li thawj kauj ruam nyob rau hauv ib qhov project yog txuam cov qib mus rau lub luag hauj lwm. Phau ntawv qhia no piv cov kev xaiv ntau: 6061, 6063, 6082, 5083 thiab 7075.
6061: Tus General-Lub Hom Phiaj Cov Qauv Alloy
6061 yog ib qho txhuas -magnesium- silicon alloy uas yog tshav kub kho kom muaj zog zoo, nrog lub zog tensile ntawm 240-310 MPa hauv T6 temper. Nws ua ke lub zog nruab nrab nrog kev ua haujlwm zoo corrosion, weldability thiab machinability, uas ua rau nws xaiv lub neej ntawd rau thav ntawv, enclosures, tshuab qhov chaw, tsheb lub cev thiab kev tsim. Nyob rau hauv 3 hli thiab 5 hli daim ntawv, 6061-T6 yog yooj yim thiab yooj yim mus ua hauj lwm, txawm tias nruj khoov yuav tsum hwm qhov tsawg kawg nkaus lub vojvoog ntawm T6 mob.
6063: Cov Khoom Siv Hluav Taws Xob
6063 muaj zog qis dua 6061 tab sis zoo dua extrudability thiab nto zoo, thiab nws yog tus qauv alloy rau architectural profiles thiab hniav seem. Raws li daim ntawv, nws tsis tshua muaj ntau tshaj 6061, tab sis nws tshwm nyob rau hauv vaj tse vaj huam sib luag thiab luas qhov twg ib tug zoo nto tiav thiab zoo anodizing teb teeb meem. Qhov twg lub zog tsis tseem ceeb, 6063 muaj kev tiv thaiv corrosion zoo heev thiab zoo li tus nqi nruab nrab.
6082: Siab zog rau kev thauj mus los thiab tshuab
6082 yog ib tug siab dua - cov tswv cuab ntawm Al-Mg-Si tsev neeg, nrog tensile lub zog nyob rau hauv lub T6 mob nyob ib ncig ntawm 310-340 MPa. Nws yog siv rau kev thauj khoom, crane thiab platform cov qauv, thiab cov tshuab uas 6061 tsis muaj zog txaus tab sis qhov kev tiv thaiv corrosion ntawm 6xxx series tseem xav tau. Nyob rau hauv 3-5 hli daim ntawv thiab phaj, 6082-T6 muab qhov zoo sib npaug ntawm lub zog, weldability thiab formability, thiab nws yog dav muaj nyob rau hauv cov teb chaws Europe thiab Asia raws li EN cov qauv.
5083: Lub Welded thiab Marine Workhorse
5083 yog ib qho uas tsis yog- cua sov- kho tau aluminium-magnesium alloy nrog zoo heev ntsev dej corrosion kuj thiab weldability. Nyob rau hauv tempers xws li H111, H116 thiab H321, 5 hli phaj muaj tensile zog ntawm 270-350 MPa thiab ua rau nws toughness ntawm tsawg kub. Nws yog tus qauv kev xaiv rau cov qauv welded, nkoj hulls, tso tsheb hlau luam thiab cov khoom siv cryogenic, qhov uas muaj peev xwm vuam yam tsis poob lub zog yog qhov kev txiav txim siab. Rau 3-5 hli ntawv, 5083-H111 yog ib hom marine thiab fabrication qib.
7075: Lub zog siab tshaj plaws, cov xwm txheej tshwj xeeb
7075 yog zinc-raws li alloy nrog lub zog siab tshaj plaws ntawm pab pawg, feem ntau 510-570 MPa tensile hauv T6, thiab nws yog siv rau hauv aerospace, tiv thaiv thiab siab -kev ua haujlwm engineering. Nws tsis haum rau kev pabcuam corrosion dav dav yam tsis muaj kev tiv thaiv, nws nyuaj rau vuam, thiab nws raug nqi ntau dua li lwm qib. Rau 3-5 hli daim ntawv, 7075-T6 lossis T651 tsuas yog tau teev nyob rau qhov twg qhov sib piv ntawm lub zog-rau-qhov hnyav ua rau tus nqi siab dua thiab tus qauv tsim tuaj yeem muab kev tiv thaiv corrosion thiab tsis-welded koom.
Yuav xaiv li cas rau koj daim ntawv thov
Pib nrog kev pabcuam ib puag ncig thiab kev thauj khoom. Rau kev tsim thiab thav duab, 6061-T6 yog qhov ua tau zoo. Rau cov qauv welded hauv corrosive lossis marine kev pabcuam, siv 5083. Rau kev thauj khoom siab dua qhov twg vuam tsis tas yuav tsum tau xav txog 6082-T6. Rau lub zog hnyav nrog qhov hnyav, 7075 yog cov lus teb, nrog rau nws cov kev txwv tau txais. Paub meej tias thickness, temper, nto thiab tus qauv nrog tus neeg muag khoom, thiab thov daim ntawv pov thawj khoom siv rau cov qauv siv.
