Uamea uamea fa'avevela eletise (fa'avevela fa'aeletise) o se fa'alava u'amea e pei o le atigi, ma uaea fa'avevela fa'avevela eletise eletise (nickel-chromium, iron-chromium alloy) o lo'o fa'asoa fa'atasi i le itu tutotonu o le faagaau. O avanoa e faʻatumuina ma faʻapipiʻi i le magnesium oxide pauta ma le faʻamalu lelei ma le faʻafefe. O pito uma e lua o loʻo faʻamaufaʻailogaina ile silica gel poʻo keramika. O lenei uʻamea faʻamafanafana eletise eletise e mafai ona faʻaaogaina lautele mo le faʻamafanafanaina o le vai, suauʻu, ea, vaifofo nitrate, vaifofo oona, vaifofo alkali ma metala maualalo maualalo (alumini, zinc, apa, babbitt alloy), E iai le lelei o le faʻamafanafana lelei. , vevela toniga, maualuga le vevela tetee, corrosion tetee, ma lelei faatinoga saogalemu.
