O le fa'afufu fa'afufu fa'au'u e fa'aaogaina le peleue fa'alava uamea, fa'aliliuina le pa'u o le magnesium oxide, le fa'aogaina o le nickel-chromium electrothermal wire ma isi mea. O lenei faʻasologa o vai faʻavevela vai e mafai ona faʻaaogaina lautele i le faʻamafanafanaina o le vai, suauʻu, ea, vaifofo nitrate, vaifofo oona, vaifofo alkali ma metala maualalo maualalo (alumini, zinc, apa, alloy Babbitt). E lelei faʻamafanafanaga lelei, vevela toniga, maualuga vevela tetee, corrosion tetee ma lelei faatinoga saogalemu.
