1. Cov yam ntxwv tseem ceeb thiab cov khoom tso tawm
5xxx series aluminium ntawv yog ib xeb txhuas cov lus nrog magoy tseem ceeb, uas muab sib xyaw ua ke, xeb tsis kam thiab formability zoo. Cov neeg raug cov ntsiab lus magnesium los ntawm 1. 0}% rau 5. {}}}%. Cov tub ntxhais cov txuj ci ua tau muaj xws li:
Corrosion Kuj: Zoo tshaj plaws hauv kev ua tub rog marine, thiab zoo dua dej hiav txwv corrosion tsis zoo dua li cov alloys feem ntau;
Formancion: elongation ntau dua los yog sib npaug rau 2 {2}}}}}}}}), ua haujlwm rau cov txheej txheem sib sib zog xws li sib sib zog nqus thiab ncab;
Weldability: Zoo heev vuam kev kawm, uas tuaj yeem ua tau raws li kev tsheb ciav hlau txuas ntxiv ntawm lub cev tso tsheb hlau luam (tsheb tso tsheb hlau luam).

| Teem nqi | Cov ntsiab lus magnesium | Tensile lub zog (mpa) | Elongation (%) | Cov Kev Siv Raug Raug |
|---|---|---|---|---|
| 5052 | 2.2–2.8% | Ntau dua los yog sib npaug rau 270 (T6 lub xeev) | Ntau dua los yog sib npaug rau 127 | Tsheb tso tsheb hlau roj tsheb, nkoj sheet hlau seem, hluav taws xob vaj tse |
| 5083 | 4.0–4.9% | Ntau dua los yog sib npaug rau 275 (h116 xeev) | Ntau dua los yog sib npaug rau 148 | Marine Engineering cov qauv, tsawg-kub siab cov hlab ntsha |
| 5005 | 0.5–1.1% | Ntau dua los yog sib npaug rau 180 (O State) | Ntau dua los yog sib npaug rau 208 | Lub tsev dai kom zoo nkauj, tsheb sab hauv |
| 5082 | 4.0–5.0% | Ntau dua los yog sib npaug rau 275 (O State) | Ntau dua los yog sib npaug rau 158 | Tuaj yeem hau, hnav cov cuab yeej thauj khoom |
3.Key txheej txheem cov yam ntxwv
Cua Sov Kho Kev Kho Cua Sov
Tsis-cua sov kho hom: xws li 5052 thiab 5083, vam khom rau kev ua haujlwm txias, tsim nyog rau kev kho mob uas tsis tas yuav tom qab stamping;
Annealing Txheej Txheem: {400-450} degree anegerting tuaj yeem tshem tawm cov kev ntxhov siab uas muaj kev ntxhov siab thiab txhim kho ib qho kev pab ua ntej ua ntej Stamping).
Nto Kho
Kev zas xim zoo heev tom qab anodizing (xws li 5005 aluminium ntawv thiab 6063 profile xim kev sib koom tes);
Pre-areasing kev kho (alkaline tu tus neeg sawv cev) yog yuav tsum ua kom ntseeg tau tias cov txheej txheej co kom zoo tshaj lossis sib npaug rau 95%.

| Kev ua hauj lwm | Daim Ntawv Thov Kev Thov | Siv tau cov qib | Qhov Zoo |
|---|---|---|---|
| Kev Lag Luam Automotive | Roj Tso Tsheb Hlau Luam, Panels Lub Cev | 5052, 5038 | High Fatue Zog (5052 tuaj yeem ncav cuag 120 MPA) |
| Nkoj shineering | Hull qauv, lawj | 5083, 5086 | Dej hiav txwv corrosion (txhua xyoo corrosion tsawg dua lossis sib npaug rau 0. 02 hli) |
| Kev lag luam ntim | Tuaj yeem hau, ntim kua | 5082, 5182 | Tsis muaj cov kab nrib pleb tom qab stamping (kev sib piv sib piv tau tuaj yeem ncav cuag 2.5) |
| Kev Tsim Kho Vaj Tse | Kab Hlau Xwv Phab Ntsa Panels, Ru Anti-Skid daim phiaj | 5005, 5052 | Hnav khaub ncaws (ntom ntom 2.68 g \/ cm³) + Cua siab Kuj |
