Konservacija kovinastih predmetov zahteva poseben študij. Kovine spre-, mene obliko in izgube lastnosti zaradi korozije in zaradi tvorbe mineralnih inkrustov. Te spremembe povzroča vrsta kemičnih in elektrokemičnih reakcij/ Hitrost razkroja predmeta je odvisna od narave kovine in od pogojev, v katerih je bila. Korozijo moremo ustaviti.
