2014 aluminium alloy alloying caij yog tooj liab, uas yog hu ua tawv txhuas. Nws muaj lub zog siab thiab kev ua haujlwm zoo, tab sis nws cov corrosion kuj tsis zoo. Dav siv dav hauv cov qauv dav hlau (daim tawv nqaij, pob txha pob txha, tav nqaj, bulkhead, thiab lwm yam) rivets, missile Cheebtsam, tsheb log hubs, kiv cua Cheebtsam, thiab lwm yam structural Cheebtsam.
Feature ntawm Aluminium 2014:
2014 aluminium alloy yog ib qho nyuaj aluminium alloy thiab wrought aluminium alloy. Piv nrog rau 2A50, vim nws cov ntsiab lus tooj liab siab, nws muaj zog dua thiab zoo dua thermal zog, tab sis nws cov yas hauv lub xeev kub tsis zoo li 2A50. 2014 aluminium alloy muaj zoo machinability, zoo sib cuag vuam, chaw vuam, thiab seam vuam, tsis zoo arc vuam thiab roj vuam kev ua tau zoo; tuaj yeem kho cua sov thiab ntxiv dag zog, nrog cov nyhuv extrusion.
Kev siv ntawm Aluminium 2014:
Siv rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab hardness (xws li kub kub). Xws li aircraft hnyav luag hauj lwm, forgings, slabs thiab extruded cov ntaub ntawv, lub log thiab cov yam ntxwv Cheebtsam, multi-theem foob pob ua ntxaij thawj theem roj tank thiab spacecraft qhov chaw, tsheb ncej thiab ncua kev kawm ntawv qhov system.
Thaum tshav kub kub kho Specification ntawm Aluminium 2014:
1) Homogenization annealing: cua sov 475 ~ 490 ° C; tuav 12 ~ 14h; cub cua txias.
2) Ua kom tiav annealing: cua sov 350 ~ 400 ° C; nrog cov thickness zoo ntawm cov khoom, lub sijhawm tuav yog 30 ~ 120min; nrog rau qhov kub ntawm 30 ~ 50 ° C / h nrog rau qhov cub txias rau 300 ° C, thiab tom qab ntawd cua txias.
3) Kev nrawm nrawm: cua sov 350 ~ 460 ° C; tuav lub sij hawm 30 ~ 120min; cua txias.
4) Quenching thiab aging: quenching 495 ~ 505 ° C, dej txias; natural aging chav kub 96h.
Cov xwm txheej: extruded aluminium thiab aluminium alloy bar (≤22mm, H112, T6)
