Raws li cov khoom siv tshiab, aluminium alloy raj yog dav siv hauv aviation, tsheb, khoom siv hluav taws xob thiab lwm yam lag luam. Piv nrog rau cov khoom siv hauv cov kav dej, cov kav dej txhuas alloy muaj cov thermal conductivity thiab corrosion kuj, tab sis lawv muaj cov nram qab no tsis xws luag thaum siv los ua cov kav dej:
1. Kev ua haujlwm ntawm cov kav dej aluminium alloy yog qhov cuam tshuam zoo heev los ntawm ib puag ncig, thiab nws yooj yim rau corroded los ntawm cov kua qaub muaj zog, muaj zog alkalis thiab hnyav hlau ions, ua rau cov dej paug thiab ua rau tib neeg noj qab haus huv.
2. Cov dej nruj ntawm cov yeeb nkab aluminium alloy yog qhov tsis zoo, thiab qhov sib txawv ntawm cov yeeb nkab phab ntsa yog qhov loj, uas yooj yim ua rau cov dej xau thiab dej.
3. Cov yeeb nkab aluminium alloy tsis tuaj yeem tiv taus qhov cuam tshuam ntawm cov dej ntws siab, thiab yooj yim tawg lossis deform, uas cuam tshuam rau qhov zoo thiab kev nyab xeeb ntawm cov dej.
Hauv cov ntsiab lus, txawm hais tias aluminium alloy kav dej muaj cov thermal conductivity zoo heev thiab corrosion kuj, lawv muaj ntau yam tsis xws luag thiab tsis haum rau siv raws li cov kav dej. Xaiv cov ntaub ntawv tsim nyog rau kev tsim cov yeeb nkab dej yog qhov tsim nyog ntawm kev ua kom zoo thiab kev nyab xeeb ntawm cov dej.
