Waya Pt-iridium bụ ọnụọgụ ọnụọgụ abụọ dabere na platinum nwere selenium. Ọ bụ ngwọta siri ike na-aga n'ihu na elu okpomọkụ. Mgbe ejiri nwayọọ nwayọọ mee ka ọ dị jụụ ruo 975 ~ 700 ºC, nbibi siri ike na-apụta, mana usoro nha nha na-aga n'ihu nke ukwuu. Ọ nwere ike melite nguzogide corrosion nke platinum n'ihi na ọ dị mfe volatilite na oxidation. E nwere Ptlr10, Ptlr20, Ptlr25, Ptlr30 na ndị ọzọ alloys, na elu hardness na elu agbaze ebe, elu corrosion eguzogide na ala kọntaktị na-eguzogide, na chemical corrosion ọnụego bụ 58% nke platinum dị ọcha, na oxidation arọ ọnwụ bụ 2.8mg / g. . Ọ bụ ihe kọntaktị eletrịkị ochie. A na-eji ya maka kọntaktị mgbanye dị elu nke engines aero-engine, kọntaktị eletriki nke relays na nnukwu uche na Wei Motors; potentiometers na brushes na-eduzi nke ihe mmetụta ziri ezi dị ka ụgbọ elu, ngwa agha na gyroscopes.
