Raws li kev npaj thiab cov xwm txheej zoo ntawm cov khoom siv aluminium thiab cov kev xav tau ntawm cov khoom siv rov ua dua tshiab, cov khoom sib xyaw raug xaiv thiab ntau npaum li cas ntawm txhua hom khoom raug xam. Cov khoom xyaw yuav tsum xav txog qhov degree ntawm oxidation burning poob ntawm cov hlau. Lub oxidation hlawv poob ntawm silicon thiab magnesium yog ntau dua li ntawm lwm yam alloying ntsiab.
Qhov kub poob tus nqi ntawm ntau yam alloying ntsiab yuav tsum tau txiav txim los ntawm kev sim ua ntej. Lub cev specifications thiab deg huv si ntawm seem aluminium yuav ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom siv dua tshiab thiab cov khoom siv hlau tiag tiag. Rau cov seem txhuas uas tsis huv ntawm cov roj, txog li 20% ntawm cov khoom xyaw nquag yuav nkag mus rau hauv slag.
Cov deformed aluminium alloys uas tuaj yeem tsim los ntawm cov khoom seem aluminium alloys suav nrog 3003, 3105, 3004, 3005, 5050, thiab lwm yam, ntawm cov 3105 alloy feem ntau yog tsim. Txhawm rau kom ntseeg tau tias cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom siv hlau ua tau raws li cov kev xav tau thiab cov txheej txheem xav tau ntawm kev ua haujlwm siab, ib feem ntawm cov khoom siv txhuas txhuas yuav tsum tau ntxiv thaum tsim nyog.
