① Kev txiav txim siab ntawm tag nrho cov kev ua tiav Tag nrho cov txheej txheem yog hais txog tag nrho cov deformation degree ntawm cov ntawv ci tom qab recrystallization annealing rau dov tawm cov khoom tiav. Feem ntau hais lus, tag nrho cov kev ua tiav ntawm 1 series tuaj yeem ncav cuag ntau dua 99 feem pua, thiab qee cov khoom 8 series kuj tuaj yeem ncav cuag tus nqi no, tab sis tag nrho cov txheej txheem ntawm aluminium alloy foil feem ntau qis dua 90 feem pua.
② Kev txiav txim siab ntawm qhov kev ua tiav Kev txiav txim siab ntawm qhov kev ua tiav yog qhov tseem ceeb ntawm cov txheej txheem dov. Qhov kev ua tiav ntawm cov khoom siv ntshiab aluminium series tuaj yeem ncav cuag 65 feem pua. Thawj kis tom qab lub billet yog annealed yuav tsum tsis txhob loj dhau. Tus nqi ua feem ntau yog li 50 feem pua.
