Qhov kawg Encyclopedia ntawm 1050 Aluminium Ntawv (Kev lag luam Pure Aluminium): In-depth Analysis los ntawm Metallurgy mus rau Kev Siv Tau
Kuv. Txheej txheem cej luam thiab cov khoom siv
1050 Aluminium Ntawvbelongs rau lub 1xxx series txhuas alloys. Raws li thoob ntiaj teb naming conventions, nws sawv cev rau kev lag luam ntshiab txhuas nrog cov ntsiab lus txhuas tsis tsawg dua 99.5%. Nws feem ntau raug xaiv raws li 1050nyob rau hauv Suav National Standard (GB / T), thaum nyob hauv European qauv (IN), nws feem ntau hu ua AW-1050A (EN AW-Al99.5)nrog rau tus lej xaiv 3.0255. Nws kuj yog ib qho kev sau npe kawm qib hauv Aluminium Association (Ib) tus qauv.
Raws li ib tug tsis yog-tshav kub-kho kom zoo, tus nqi tseem ceeb ntawm 1050 tsis dag nyob rau hauv nws mechanical zog, tab sis theej hauv nws tshuaj lom neeg ruaj khov heevthiab lub cev muaj zogcov (hluav taws xob conductivity, thermal conductivity, thiab reflectivity). Nws plays lub luag hauj lwm ntawm a “cov khoom siv hauv paus” hauv tsev neeg aluminium alloy, piv rau me ntsis steel (E.G., q235 ua) hauv kev lag luam steel. Nws cov txheej txheem ntau lawm thiab cov nqi qis qis / dov ua rau nws yog cov khoom siv pob zeb rau kev sib txuas, kev coj ua, anti-corrosion, thiab sib sib zog nqus stamping daim ntawv thov.
🔍 In-depth Interpretation:
- Vim li cas xaiv 1050 saum 1060?Thaum 1060 muaj purity ntau dua (99.6%), 1050 muab qhov zoo sib npaug ntawm lub zog thiab formability, thiab feem ntau yog tus nqi sib tw ntau dua.
- Dab tsi “non-kub-kho tau” siab phem?Nws txhais tau tias koj tsis tuaj yeem nce nws qhov nyuaj los ntawm quenching thiab kev laus li koj xav nrog 6061-T6. Nws lub zog tsuas yog nce los ntawm ua haujlwm txias (dov, daim duab).
II. Metallurgical yam ntxwv thiab Micro-Mechanisms

Q&A
Qi1: Ua tau 1050 aluminium ntawv siv rau nkoj decks lossis cov khoom siv hauv cov dej hiav txwv?
A:cov Tsis pom zoo kiag li.Txawm tias 1050 resists atmospheric corrosion, nws yog rhiab heev rau chloride ions (Cl⁻). Dej hiav txwv yog nplua nuj nyob rau hauv chlorides, uas tuaj yeem ua rau pitting corrosion thiab crevice corrosion, sai nkag mus rau nyias daim ntawv. Marine ib puag ncig yuav tsum siv 5xxx series (E.G., 5052, 5083) Al-mg alloys, uas muaj kev tiv thaiv zoo rau dej hiav txwv.
Q2: Vim li cas H14 npau taws 1050 aluminium ntawv tawg yooj yim thaum khoov?
A:Yuav muaj peb yam:
- Khoov Radius me me dhau: Txawm hais tias H14 yog ib nrab nyuaj, nws tseem yuav tsum tau ua raws li qhov tsawg kawg nkaus khoov vojvoog (feem ntau pom zoo 1.0t ~ 1.5t, qhov twg t yog phaj thickness); me me dhau R lub kaum sab xis yuav ua rau sab nrauv tawg.
- Noob Direction (Anisotropy): Cov ntawv txhuas muaj fiber ntau cov kev taw qhia thaum dov. Bendability yog qhov zoo tshaj plaws yog tias txoj kab bending yog perpendicular mus rau dov kev taw qhia; Nws yog qhov zoo dua yuav tawg yog tias thaum uas tig mus rau qhov kev taw qhia dov.
- Khoom siv impurities: Yog hais tias hlau thiab silicon impurities nyob rau ntawm lub siab txwv, los yog cov nplej loj yog ntxhib, plasticity kuj yuav txo.
Q3: Ua tau 1050 Ua haujlwm nyuaj Anodizing?
A:cov Nyuaj thiab tsis pom zoo.Hard anodizing feem ntau yuav tsum muaj cov ntsiab lus xws li magnesium thiab silicon (E.G., 6061) los txhawb lub hardness thiab adhesion ntawm tuab oxide zaj duab xis. Cov oxide zaj duab xis tsim los ntawm ntshiab txhuas 1050 yog qhov muag muag thiab tsis yooj yim los ua ib zaj duab xis tuab (feem ntau <25μm), thiab nws cov hardness thiab hnav tsis kam yog nyob deb ntawm kev ua raws li cov qauv nyuaj anodizing.
Qi4: Vim li cas 1050 aluminium ntawv qee zaum tig dub los yog tsim cov pob dawb tom qab khaws cia rau lub sijhawm?
A:Qhov no feem ntau yog vim ntim tsis zoo.
- Qhov chaw dawb: Feem ntau yog dej stains lossis alkaline residues. Cov dej nyob nruab nrab ntawm cov nplooj ntawv tsis tuaj yeem evaporate, ua rau lub zos corrosion.
- Dub: Tej zaum cov roj oxidation los yog kev sib cuag nrog roj hmab / sulfide-tso plastics. Ib txwm siv cov khoom ntim nruab nrab thiab xyuas kom lub tsev khaws khoom qhuav thiab qhov cua.
Q5: Puas muaj tus nqi loj sib txawv ntawm 1050 thiab 1060? Qhov twg nws feem ntau txawv?
A:Tus nqi sib txawv ib tuj feem ntau yog ob peb puas RMB. Qhov sib txawv tsuas yog nyob rau hauv:
- Tus nqi raw khoom: 1060 xav tau ntau dua purity aluminium ingots, thiab cov khoom siv rov ua dua tshiab yog nruj dua.
- Txheej txheem tswj: Kev tsim tawm 99.6% purity aluminium ntawv yuav tsum finer impurity tswj txheej txheem dua 99.5%.
- Application Distinction: Yog hais tias qhov yuav tsum tau rau conductivity yog tsis heev tseem ceeb heev (E.G., zoo tib yam heat sinks vs. ultra-siab voltage busbars), 1050 muab cov nqi zoo dua.
Q6: Kuv yuav ua li cas yog lub zog ntawm 1050 aluminium ntawv txo qis tom qab vuam?
A:Qhov no yog ib txwm tshwm sim (annealing nyhuv). Arc cua sov ua rau qhov txias-ua hauj lwm hardening nyhuv nyob rau hauv lub weld thiab tshav kub-cuam tshuam cheeb tsam kom ploj, rov qab mus rau lub xeev mos nyob ze rau O temper. Yog tus qauv xav tau lub zog, tus cross-sectional thickness ntawm weld yuav tsum tau ncethaum lub sij hawm tsim los them rau lub zog poob, los yog xav txog kev siv cov txheej txheem kev sib txuas xws li riveting lossis nplaum nplaum es tsis txhob siv vuam.
