Aluminium ntawv ci yog nyias nyias, raws li tau teev tseg los ntawm International Standards Organization: lub thickness ranges ntawm {{0}}.2mm mus rau huab 0.006 hli. Kev tsim cov txheej txheem ntawm aluminium ntawv nyiaj yuav dov los ntawm 2 hli thiab 4 hli daim hlau. Nyob rau hauv cov txheej txheem no, cov txhuas blanks txias dov nyob rau hauv ib ntus kom txog rau thaum lub coil mus txog qhov yuav tsum tau thickness. Aluminium ntawv ci muaj qhov zoo rwb thaiv tsev tiv thaiv lub teeb, oxygen, saj, noo noo, thiab kab mob. Nws yog dav siv hauv cov khoom noj thiab tshuaj ntim khoom. Nyob rau hauv cov txheej txheem ntxaib zeb, ob foils raug muab sib cais ib txhij, cia cov ntawv nyias nyias (thickness li ntawm 6 txog 30µm) tau txais.
Vim yog qhov micro-kev nkag mus ntawm cov ntawv nyias nyias, ib puag ncig tsim khoom thiab lwm yam laj thawj, pinholes yuav inevitably tshwm sim thaum lub sijhawm tsim khoom. Txoj hauv kev ib txwm muaj yog npaj kev tshuaj xyuas phau ntawv ntawm cov pinholes thaum lub sij hawm rewinding txheej txheem; Txawm li cas los xij, vim tib neeg lub qhov muag qaug zog, txwv tib neeg lub qhov muag daws teeb meem, thiab cov nqi ua haujlwm siab, 100% kev tshuaj xyuas qhov muag tsis tuaj yeem ua.
