O lenei oloa e fa'aaogaina matai u'amea e pei o mea mata, fa'aogametallurgy pautatekinolosi
e gaosia ingots u'amea, ma e gaosia e faapitoa malulu ma vevela faagasologa ma vevela
faiga togafitiga. O le oloa o loʻo i ai le lelei o le malosi faʻamaʻi faʻamaʻi, lelei
tete'e corrosion i le vevela maualuga, fetolofi laiti o vaega electrothermal, auaunaga umi
ola i le vevela maualuga ma suiga laiti o le tetee. E fetaui mo le maualuga o le vevela 1420 C,
maualuga malosi density, corrosive atemosifia, siosiomaga carbon ma isi siosiomaga galuega.
E mafai ona faʻaaogaina i ogaumu sima, ogaumu vevela vevela vevela, ogaumu suʻesuʻe,
ogaumu tau alamanuia faaeletonika ma ogaumu faasalalau.
