1. Dab tsi yog cov khoom ntawm aviation aluminium
Ntxiv nrog rau txhuas, cov khoom tseem ceeb ntawm aviation aluminium kuj tseem ntxiv nrog magnesium, uas yog aluminium alloy hlau thiab cov khoom siv los ntawm kev txhim kho aviation. Cov khoom no tsuas yog siv nyob rau hauv guardrails, stair handrails, los yog ruaj ruaj qhov rais. Ob qho tib si ntawm cov tsos thiab kev ua tau zoo, nws yog qhov ruaj khov dua li aluminium alloy ncej, thiab nws yog cov khoom siv high-tech.
2. Dab tsi yog qhov txawv ntawm aviation txhuas thiab zoo tib yam txhuas
① Ua ntej tshaj, cov khoom sib txawv. Qhov kev xaiv tseem ceeb rau aviation aluminium yog 7 series ntawm aluminium alloy profiles, thiab cov khoom siv txhuas feem ntau yog 6 series ntawm aluminium alloy profiles.
② Tib lub sijhawm, muaj qhov sib txawv ntawm kev ua tau zoo thiab hardness. Lub 7 series txhuas cov ntaub ntawv muaj qhov hardness siab tshaj plaws thiab tuaj yeem siv rau hauv thaj chaw aerospace. Aluminium alloy ntawm 6 series muaj qhov nruab nrab hardness, uas tuaj yeem ua tau raws li qhov xav tau ntawm lub neej.
③ Tus nqi kuj txawv, cov ntaub ntawv xaiv txawv, thiab tus nqi kuj txawv. Yog tias qhov hardness siab dua, nws nyuaj rau kev tsim, thiab cov txheej txheem ntau lawm yog siab dua. Hauv kev ua lag luam, tus nqi ntawm aviation aluminium profiles yog siab dua. 6 series ntawm aluminium alloys, uas yog, zoo tib yam txhuas, feem ntau siv yog 6061 los yog 6063, nrog rau nruab nrab hardness, extrusion molding, thiab cov nqi ntau lawm.
④ Kev ua haujlwm sib txawv. Aluminium alloy profiles tsis tuaj yeem welded, tab sis tuaj yeem txuas nrog lwm txoj kev. Ordinary txhuas tuaj yeem welded, yog li nws muaj ntau yam kev siv.
⑤ Txawv corrosion kuj. Kev tiv thaiv corrosion ntawm aviation aluminium yog qhov tsis zoo, thiab qhov chaw tsuas tuaj yeem ua tiav qee qhov kev tiv thaiv corrosion tom qab kev kho tshwj xeeb. Txawm li cas los xij, 6 series aluminium alloy nws tus kheej muaj qee yam kev tiv thaiv corrosion, thiab kev kho oxidation ntxiv, uas tuaj yeem txhim kho oxidation kev ua tau zoo.
