Dab tsi ua rau 3104 alloy tshwj xeeb haum rau dej haus tuaj yeem lub cev?
Aluminium 3104 yog cov qauv kev lag luam rau lub cev muaj peev xwm vim nws tshuav nyiaj zoo tshaj plaws (lub zog tensile zoo: 240-285 MPa) thiab muaj peev xwm (elongation: 10-17%). Nws tus manganese (1.0-1.5%) thiab magnesium (0.8-1.3%) cov ntsiab lus tau ua rau muaj kev sib sib sib nqus nqus duab thaum ua tau. Cov Alloy tswj cov qauv txheej txheem kev ntseeg nyob rau sab hauv thaum ua lub teeb yuag. Rov qab siv sib xyaw (ntau dua 70% ntawm cov canS siv rov qab siv 3104) thiab FDA pom zoo rau kev sib tiv tauj ntxiv rau nws txoj kev. Piv rau 3004, 3104 muaj zoo corrosion zoo dua tawm tsam cov acidic haus acidic.
Yuav ua li cas qhov kev kub siab (H19 vS H38) cuam tshuam 3104 phaj ua tau zoo?
H19 Tauj Sim Qhia tag nrho nyuaj (txias ua haujlwm75+%), ua tiav ntau tshaj plaws yog - zoo tshaj plaws uas yuav tsum tau rigidity. H38 (kev nyuaj tshwj xeeb) muab kev sib txuas lus nruab nrab ntawm kev ua kom yooj yim rau kev ua kom yooj yim dua thaum tswj hwm lub siab tiv taus. H19 nplooj ntawv feem ntau qhia 285 MPA tensile lub zog piv rau H38 lub sijhawm 250 MPa. Ob qho tib si tempers uas yiag ntawv ci stabilization ci ntawm 150-200 kev kawm kom tiv thaiv hnub nyoog softening. H38 yog qhov zoo tshaj rau cov phiaj hlau thicker (> 0.5mm) qhov twg yuav tsum muaj kev tsim cov tsiaj ntawv tom qab ntau lawm.
Dab tsi yuav yog vuam ceev faj yog qhov tsim nyog rau 3104 alloy pab ntaubrication?
Roj Hlau Hlau Arc Vuam (Gmaw) nrog ER4043 muab tub lim kom tsis txhob tawg kev kub ntxhov. Preheat rau 150 rho me ntsis thermal kev ntxhov siab nyob rau hauv ntu tshaj 6mm tuab. Tom qab kev kho cua sov ntawm 250℃rau 1 teev restores corrosion tsis kam nyob rau hauv cov cheeb tsam kub-cuam tshuam. Tsis zoo li 5xxx alloys, 3104 yuav tsum tsis txhob welded rau magnesium-nplua nuj alloys vim yog intermetallic brittleness. Laser Vuam yog nce siv rau thin-gauge tuaj yeem npaj nrog <0.3mm kerf dav.
Vim li cas 3104 tso tawm cov fardain farden hardening piv rau 3003?
Cov ntsiab lus ntau dua Magnesium (1.0% vs 0.1% hauv 3003) ua rau muaj kev cuam tshuam zoo dua thaum ua haujlwm txias. Manganese Dispersoids (Theem Al6MN) muab cov kev txhawb zog ntxiv los ntawm cov ciaj ciam ua kom tawv tawv. Ua haujlwm Hardening Exponent (N-tus nqi) ntawm 3104 txog ntawm 0.206 txog 3003 tso cai rau 3104 kom ua tiav H19 TOMER ZAUB TSIS MUAJ IB LAWM INTERMEDICING. Lub Alloy's Stacking Txhaum Zog (-200 MJ / M²) cov kev sib tw ua tau zoo thiab ua kom pom tseeb.
Dab tsi ASTM / ISO Cov Qauv kav 3104 txhuas daim ntawv tsim khoom?
ASTM B209 qhia meej cov tuab ua zam (± 0.05 hli rau 0.2 hli ntawv) thiab cov khoom siv mechanical. EN 485-2 Kev tswj hwm European tuaj yeem nqa cov qhov ntev. ISO 6361-2 Txhais Tau H19 Tas Dej Yuav Tsum Tau Ua (Pom Zoo Lub Zog Ntau dua lossis sib npaug nrog 260 MPA). Aluminium Tuam Koom Haum Teal Cov npe Sau Cov Tshuaj Pom Zoo (MN: 0.8-1.5%, Fe <0.8%). Cov tuam txhab tuaj yeem ua rau cov qauv sab hauv xws li "AA3104-H19 / E" rau kev siv cov yam ntxwv sib xws (<2.5% pob ntseg sib piv).
