Pt-iridium waya iplatinum-based binary alloy ine selenium. Iyo inoenderera yakasimba mhinduro pane yakakwirira tembiricha. Kana ikatonhodzwa zvishoma nezvishoma kusvika pa 975 ~ 700 ºC, kuparara kwechikamu chakasimba kunoitika, asi chikamu chekuenzanisa chinoenda zvishoma nezvishoma. Inogona kuvandudza zvakanyanya kushora kweplatinamu nekuda kwekudzika kwayo kuri nyore uye oxidation. Kune Ptlr10, Ptlr20, Ptlr25, Ptlr30 uye mamwe maalloys, ane kuomarara kwepamusoro uye kunyungudika kwakakwira, kushomeka kwecorrosion uye kushomeka kwekushomeka, kemikari yecorrosion rate ndeye 58% yeplatinum yakachena, uye iyo oxidation uremu kurasikirwa ndeye 2.8mg/g. . Icho chinhu chekare chemagetsi chekubata zvinhu. Inoshandiswa kune yakakwira yekubatidza mabikirwo eaero-injini, magetsi ekubatanidza erelays ane yakanyanya senitivity uye Wei mota; potentiometers uye conductive mhete mabhurashi eiyo chaiyo sensors senge ndege, zvombo zvinokandwa uye gyroscopes.
Inoshandiswa zvakanyanya mumiti yemakemikari, filaments, spark plugs
