Vim yog cov tuab ntawm txheej, nws tuaj yeem muab faib ua ib txheej (4-20 microns); ob txheej txheej (25-28 microns); peb txheej (35-38 microns);
Vim yog cov qauv ntawm qhov chaw, nws tseem hu ua luam ntawv aluminium coil; vim nws txoj kev siv sib txawv, nws kuj tseem hu ua cov khoom siv ru tsev (txhuas aluminium magnesium manganese vov tsev), cov khoom siv qab nthab (rau kev ua aluminium alloy ceilings), thiab cov khoom siv hauv tsev (rau cov khoom siv hauv tsev). Sab hauv thiab sab nrauv kho kom zoo nkauj, ua raws li EU Rohs cov qauv), cov khoom noj khoom haus (khoom noj khoom haus qib chromium txheej thiab cov menyuam txheej, ua raws li US FDA cov qauv), cov ntawv txhuam hniav (nto kho nrog txhuam), thiab lwm yam.
3003 txhuas kauj yog siv dav siv txhuas hlau vim tias tus nqi ntawm 3003 txhuas kauj yog tsim nyog rau feem ntau kev lag luam. Nws yog tsim los ntawm txhuas, tooj liab, hlau, manganese, silicon thiab zinc. Nws yog dav siv vim nws muaj zog corrosion kuj thiab nruab nrab lub zog. 3003 txhuas kauj yog 20% muaj zog dua 1100 qib alloy vim nws yog fused nrog manganese. Lub zog ntawm cov hlau no tuaj yeem nce los ntawm kev ua haujlwm txias.
