Aluminium ntawv ci tuaj yeem muab faib ua cov ntawv tuab, ib qho xoom ntawv thiab ob npaug xoom ntawv raws li qhov sib txawv ntawm cov tuab.
① Thick foil ("heavy gaugefoil"): ntawv ci nrog lub thickness ntawm {{0}}.1 txog 0.2mm.
② Ib daim ntawv xoom ("cov ntawv ntsuas nruab nrab"): Ntawv ci nrog lub thickness ntawm {{0}}.01mm thiab tsawg dua 0.1mm /.
③ Muab ob npaug rau xoom ntawv ("lub teeb gauge ntawv ci"): Lub npe hu ua ob lub xoom ntawv ci yog ntawv ci nrog ob xoom tom qab tus lej lej thaum nws thickness ntsuas hauv mm, feem ntau yog cov ntawv txhuas uas muaj thickness tsawg dua {{1} }. Nyob rau hauv txawv teb chaws, txhuas ntawv ci nrog ib tug tuab ntawm tsawg dua los yog sib npaug zos rau 40ltm yog tej zaum hu ua "light gauge foil", thiab txhuas ntawv ci nrog ib tug tuab ntawm> 40btm yog collectively hu ua "heavy gauge foil".
