O le uaea Pt-iridium o se u'amea binary fa'avae platinum e iai le seleni. Ose vaifofo mautu faifai pea ile vevela maualuga. A fa'amalie lemu i le 975-700 ºC, e tupu le fa'aleagaina o vaega mautu, ae o le fa'agasologa o le paleni e fa'asolosolo malie lava. E mafai ona faʻaleleia atili le faʻafefeteina o le platinum ona o lona faʻafefe faigofie ma le faʻamaʻiina. O loʻo i ai Ptlr10, Ptlr20, Ptlr25, Ptlr30 ma isi uʻamea, ma le maualuga o le maaa ma le maualuga o le liusuavai, maualuga le faʻafefeteina ma le maualalo o fesoʻotaʻiga faʻafesoʻotaʻi, o le chemical corrosion rate o le 58% o le platinum mama, ma o le faʻamaʻiina o le mamafa o le 2.8mg / g. . Ose mea masani fa'afeso'ota'i eletise. Faʻaaogaina mo fesoʻotaʻiga faʻafefe maualuga o aero-engine, fesoʻotaʻiga eletise o taʻavale ma le maualuga maualuga ma masini Wei; potentiometers ma pulumu mama mama o masini sa'o e pei o vaalele, missiles ma gyroscopes
