Manganese Cov ntsiab lus:Aluminium 5005 muaj nyob ib ncig ntawm 0.4% manganese, uas txhim kho lub zog thiab hnav tsis kam. Aluminium 5052 muaj cov qib manganese tsawg heev.
Mechanical Properties
Lub tshuab ua haujlwm ntawm cov hlau no txiav txim siab lawv qhov tsim nyog rau ntau yam kev siv:
Tensile zog:Aluminium 5005 ranges ntawm 110 txog 230 MPa, thaum 5052 thaj tsam ntawm 190 txog 320 MPa, ua 5052 tsim nyog rau cov ntawv thov uas xav tau lub zog ntau dua.
Fatigue Strength:Aluminium 5005 muaj zog qaug zog ntawm 38–86 MPa, whereas 5052 ranges ntawm 66–140 MPa, uas qhia tau hais tias zoo dua durability nyob rau hauv cyclic loading.
Shear Strength:Aluminium 5005 muab 70-130 MPa; 5052 muaj 120-180 MPa, ua rau nws tiv taus ntau zog.
Corrosion Resistance
Ob lub alloys tiv thaiv corrosion, tab sis 5052 yog superior, tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig, vim nws cov ntsiab lus magnesium thiab chromium ntau dua. Aluminium 5005 ua tau zoo nyob rau hauv cov huab cua puag ncig thiab yog nyiam nyob rau hauv architectural daim ntaub ntawv rau nws zoo heev anodized xim uniformity.
Khoom siv: Aluminium 5052Zoo tagnrho rau marine hardware, shipbuilding, thiab lwm yam corrosive ib puag ncig.
Aluminium 5005:Feem ntau siv rau hauv kev tsim kho, vov tsev, cladding, thiab cov khoom siv kho kom zoo nkauj uas ib puag ncig tsis zoo.
Ob lub alloys tuaj yeem ua anodized los txhim kho corrosion ntxiv. Anodized 5005 muaj cov xim zoo sib xws, thaum anodized 5052 ntxiv dag zog rau kev tiv thaiv corrosion zoo dua, ua rau nws haum rau hnyav thiab zoo nkauj - cov ntaub ntawv rhiab heev.
Weldability
Weldability yog qhov tseem ceeb rau kev tsim khoom:
Aluminium 5005:Welds yooj yim nrog MIG lossis TIG cov txheej txheem. Cov ntsiab lus magnesium qis tuaj yeem ua rau cov pob qij txha tsis muaj zog me ntsis, tab sis nws yooj yim dua rau kev ua haujlwm nrog. Pom zoo muab tub lim: 5356 rau cov haujlwm anodized.
Khoom siv: Aluminium 5052Muab qhov zoo tshaj plaws weld zog thiab durability, tshwj xeeb tshaj yog nyob rau hauv marine los yog siab - ib puag ncig kev nyuaj siab. Haum rau txhua txoj kev vuam txheej txheem. Pom zoo fillers: 4043 lossis 5356 (5356 nyiam rau anodizing).
Formability
Formability, los yog lub peev xwm mus rau undergo shaping yam tsis muaj cracking, yog cuam tshuam los ntawm muaj pes tsawg leeg thiab txhua yam khoom:
Aluminium 5005:Nrog rau nruab nrab lub zog thiab zoo ductility, nws yog ib qho yooj yim rau tsim rau hauv ntau yam duab, zoo tagnrho rau cov hniav thiab architectural Cheebtsam uas yuav tsum tau nws kim heev shaping.
Khoom siv: Aluminium 5052Cov ntsiab lus magnesium siab dua nce lub zog thaum txo qis ductility. Nyob rau hauv softer tempers (xws li O), nws tseem yog heev formable, haum rau marine, automotive, thiab kev lag luam daim ntawv thov xav tau cov duab ntev.
Tensile zog & Ductility:5005 muaj zog tensile qis (110-230 MPa) tab sis zoo elongation (1.1% - 23%), ua kom yooj yim dua . 5052 muaj zog tensile ntau dua (190-320 MPa) thiab elongation mus txog 27%, tuav zoo heev ductility rau complex forming.
Kev thov kom haum
| Khoom | Aluminium 5005 | Aluminium 5052 |
|---|---|---|
| Lub zog | Nruab nrab | Siab dua |
| Weldability | Zoo, txheem txheej txheem | Zoo heev, tag nrho cov txheej txheem txheem |
| Corrosion Resistance | Zoo nyob rau hauv atmospheric tej yam kev mob | Zoo heev, tshwj xeeb tshaj yog marine ib puag ncig |
| Kev siv yam | Roofing, cladding, hniav architectural ntsiab | Marine Cheebtsam, roj tso tsheb hlau luam, siab -kev nyuaj siab kev lag luam thiab zaub mov- qib kev siv |
Ob lub alloys muaj qhov zoo weldability thiab formability, tab sis 5052 excels nyob rau hauv lub zog, durability, thiab corrosion kuj, ua rau nws zoo tagnrho rau kev thov. Kev xaiv yuav tsum yog raws li cov kev xav tau tshwj xeeb, xav txog cov khoom siv kho tshuab, ib puag ncig, thiab tus nqi.
