Cov txheej txheem kub stamping siv lub hauv paus ntawm kub nias hloov mus hloov cov txhuas txheej hauv cov electrolytic aluminium rau saum npoo ntawm cov substrate los tsim ib cov hlau tshwj xeeb. Vim tias cov khoom siv hauv cov thawv kub yog cov khoom siv hlau electrolytic, cov txheej txheem kub kub kuj hu ua electrolytic aluminium stamping. Kev thawb kub muaj cov yam ntxwv ntawm cov qauv zoo, zoo nkauj tsos, ci xim, hnav tsis kam thiab tsis haum huab cua. Hauv kev tsim duab, bronze yuav ua tau lub luag haujlwm tseem ceeb hauv cov ntsiab lus tsim, tshwj xeeb tshaj yog rau cov lag luam thiab cov npe sau npe, cov nyhuv yog qhov zoo tshaj plaws.
