Taw qhia rau 2A12 (LY12) aluminium alloy: 2A12 yog ib qho nyuaj txhuas alloy hauv aluminium-tooj liab-magnesium system. Nws muaj pes tsawg leeg yog qhov tsim nyog thiab nws qhov kev ua tau zoo tag nrho. Ntau lub teb chaws tsim cov hlau no, uas yog siv dav tshaj plaws ntawm cov tawv txhuas.
2A12 (LY12) Cov tshuaj muaj pes tsawg leeg: Aluminium Al: Balance silicon Si: Tsawg dua lossis sib npaug rau 0.50 Copper Cu: 3.8-4.9 Magnesium Mg: 1.{{ 9}}.8 Zinc Zn: Tsawg dua lossis sib npaug rau 0.30 Manganese Mn: 0.30-0.9 Titanium Ti: Tsawg dua lossis sib npaug rau { {20}}.15 Nickel Ni: Tsawg dua lossis sib npaug rau 0.10 Hlau: 0.000-0.500 Hlau + nickel Fe + Ni: 0 .000-0.500 Nco tseg: Ib leeg: Tsawg dua lossis sib npaug rau 0.05; Tag Nrho: Tsawg dua lossis sib npaug rau 0.10
2A12 (LY12) kev kho cua sov specifications: 1. Homogenization annealing: cua sov 480 ~ 495; rwb thaiv tsev 12 ~ 14h; cub cua txias. 2. Ua kom tiav annealing: cua sov mus rau 390-430 degree ; tuav lub sij hawm 30-120min; Lub qhov cub txias rau 300 degree thiab cua txias. 3. Ceev ceev annealing: cua sov 350 ~ 370 degree; tuav lub sij hawm 30 ~ 120min; cua txias. 4. Quenching thiab aging: quenching 495 ~ 505, dej txias; dag aging 185 ~ 195, 6 ~ 12h, cua txias; natural aging: 96h ntawm chav tsev kub.
2A12 (LY12) txhuas pas nrig kev ua tau zoo thiab kev siv: 2A12 txhuas alloy phaj yam ntxwv thiab cov peev txheej ntawm daim ntawv thov: 2a12 aluminium alloy phaj yog lub zog siab zog aluminium uas tuaj yeem ua kom muaj zog los ntawm kev kho cua sov. Nws muaj nruab nrab plasticity hauv annealing, tshiab quenching thiab thermal tej yam kev mob, thiab yog qhov chaw welded. Cov hlau muaj kev ua haujlwm zoo, tab sis muaj lub siab nyiam tsim cov kab nrib pleb thaum siv roj vuam thiab argon arc vuam; lub alloy muaj zoo machinability tom qab quenching thiab txias ua hauj lwm hardening, tab sis yog tsis zoo nyob rau hauv lub xeev annealed. Kev tiv thaiv corrosion tsis siab, thiab cov txheej txheem anodizing thiab pleev xim feem ntau siv, lossis txheej txheej txhuas ntxiv rau saum npoo los txhim kho corrosion. 2A12 yog siv rau hauv cov qauv dav hlau (daim tawv nqaij, ncej, tav, bulkheads, thiab lwm yam), rivets, elastic Cheebtsam, tsheb hubs, kiv cua thiab lwm yam khoom siv ntau yam.
