Ntawm qhov tod tes,5052 aluminium alloymuaj kev tsim thiab kev ua tau zoo heev, zoo corrosion kuj, thiab nruab nrab lub zog. Nws yog dav siv nyob rau hauv kev tsim cov dav hlau roj tso tsheb hlau luam, cov kav dej, cov ntawv hlau rau cov tsheb thauj mus los, nkoj, meters, txoj kev teeb lub teeb, rivets, thiab cov khoom siv kho vajtse. Tsis tas li ntawd, nws yog siv hauv kev tsim cov dej haus tuaj yeem hau (hauv H19 temper), nrog kev txhim kho adhesion thiab corrosion kuj ua tiav los ntawm anodization. GNEE muab siab - zoo 5052 txhuas, tshwj xeeb tshaj yog rau alloy tank npog thiab lwm yam ntaub ntawv nrog kev ua haujlwm ruaj khov.
Lub 5000 series aluminium alloys feem ntau muaj aluminium thiab magnesium. Cov alloys paub txog lawv qhov nruab nrab mus rau siab zog, zoo heev tiv taus seawater corrosion, thiab tshwj xeeb weldability. Qee cov qhab nia feem ntau hauv cov koob no suav nrog 5005, 5049, 5050, 5052, 5083, 5086, 5059, thiab 5182.
Nyob rau hauv cov nqe lus ntawm lub zog thiab hardness, 5000 series alloys feem ntau muaj zog dua piv rau 3000 thiab 1000 series alloys (5xxx> 3xxx> 1xxx), nrog rau ib tug raug lub zog theem nyob ib ncig ntawm 300 MPa. Cov alloys no tau siv dav hauv thaj chaw marine, kev tsim kho ntawm ntug dej hiav txwv, cov khoom siv kho qhov muag, cov khoom siv, thiab cov thawv cryogenic.
5052 aluminium, tshwj xeeb, yog paub txog nws zoo heev corrosion kuj, tshwj xeeb tshaj yog tawm tsam seawater. Qhov no ua rau nws yog qhov kev xaiv nrov rau kev siv dej hiav txwv, xws li cov thawv xa khoom rau cov roj thiab cov roj tankers, thiab lwm cov khoom siv hauv hiav txwv - qib. Tsis tas li ntawd, 5052 txhuas yog qhov ruaj khov thiab ua tau zoo dua lwm cov hlau nplaum thaum raug cov dej hiav txwv hnyav.
Vuam 5052 txhuas yog ncaj nraim, vim nws tuaj yeem ua tau yooj yim soldered yam tsis tas yuav tsum muaj cov txheej txheem tshwj xeeb. Cov txheej txheem vuam feem ntau suav nrog hlau inert gas (MIG) vuam thiab tungsten inert gas (TIG) vuam.
Thaum muaj lwm yam alloys nrog ntau zog thiab toughness, 5052 tseem yog ib qho kev xaiv zoo nyob rau hauv ntau daim ntawv thov, muab ib tug zoo tshuav nyiaj li cas ntawm lub zog, durability, thiab corrosion kuj.
5083 aluminium, feem ntau siv nyob rau hauv shipbuilding, yog ib qho tseem ceeb alloy nyob rau hauv lub marine kev lag luam. Kev kub ntxhov rau 5083 suav nrog H111, H112, H116, thiab H321. Cov hlau no yog dav siv rau nkoj hulls thiab yachts, nrog nruab nrab mus rau tuab txhuas daim hlau ua ib yam.
5083-H111: Qhov kev npau taws no haum rau cov khoom uas tau dhau los ua haujlwm hnyav tom qab qhov kawg annealing, tab sis nrog qis qis ntawm hardening tshaj lub xeev H11.
5083-H112: Qhov kev npau taws no zoo tagnrho rau cov kub- dov daim hlau thiab kub- cov khoom ua tiav, nrog kev ua haujlwm zoo.
5083-H116/H321: Cov tempers no zoo tagnrho rau marine daim ntaub ntawv, raws li lawv muaj stability thiab tsis kam mus rau seawater corrosion.
Thaum 5052 txhuas yog yooj yim rau txheej txheem thiab tsim,5083 aluminiummuaj kwv yees li 1.5 npaug ntawm tensile thiab yield zog ntawm 5052. Qhov no txhais tau hais tias rau tib lub thickness, ib lub nkoj ua los ntawm 5083 txhuas tuaj yeem tiv taus siab ntau dua yam tsis muaj kev tawg lossis deforming piv rau ib qho ua los ntawm 5052 txhuas.
NtawmGNEE, peb muab ntau yam ntawm siab- zoo 5083 thiab 5052 aluminium alloys, kom ntseeg tau tias muaj zog, ruaj khov, thiab corrosion- tiv taus cov kev daws teeb meem rau marine thiab lwm yam kev lag luam.
