① Kev txiav txim siab ntawm tag nrho cov txheej txheem yog hais txog tag nrho cov degree ntawm deformation ntawm cov ntawv ci los ntawm recrystallization annealing rau dov rau hauv cov khoom tiav. Feem ntau hais lus, tag nrho cov kev ua tiav ntawm 1 series tuaj yeem ncav cuag ntau dua 99%, thiab qee cov khoom 8 series kuj tuaj yeem ua tiav qhov nqi no, tab sis tag nrho cov txheej txheem ntawm aluminium alloy foil feem ntau qis dua 90%.
② Kev txiav txim siab ntawm kev ua tiav yog qhov tseem ceeb ntawm cov txheej txheem dov. Rau cov khoom lag luam ntshiab aluminium series, qhov kev ua tiav tuaj yeem ncav cuag 65%. Rau thawj kis tom qab annealing ntawm lub billet, nws tsis pom zoo kom siv tus nqi siab dhau lawm, feem ntau nyob ib ncig ntawm 50%.
