Waya wa Pt-iridium ndi aloyi wopangidwa ndi platinamu wokhala ndi selenium. Ndi njira yokhazikika yolimba pa kutentha kwakukulu. Ikazizira pang'onopang'ono mpaka 975 ~ 700 ºC, kuwola kolimba kumachitika, koma njira yofananira imayenda pang'onopang'ono. Ikhoza kusintha kwambiri kukana kwa dzimbiri kwa platinamu chifukwa cha kusinthasintha kwake kosavuta komanso okosijeni. Pali Ptlr10, Ptlr20, Ptlr25, Ptlr30 ndi ma aloyi ena, okhala ndi kuuma kwakukulu komanso malo osungunuka kwambiri, kukana kwa dzimbiri komanso kukana kutsika, kuchuluka kwa dzimbiri ndi 58% ya platinamu yoyera, ndipo kuchepa kwa okosijeni ndi 2.8mg/g . Ndi tingachipeze powerenga magetsi kukhudzana zakuthupi. Amagwiritsidwa ntchito pakuyatsa kwambiri kwa ma aero-injini, kulumikizana kwamagetsi kwa ma relay okhala ndi chidwi chachikulu ndi ma injini a Wei; ma potentiometers ndi maburashi a mphete owongolera a masensa olondola monga ndege, mizinga ndi ma gyroscopes
Amagwiritsidwa ntchito kwambiri muzomera zamankhwala, ma filaments, ma spark plugs
