Ir3Au

Ir₃Au is a precious metal intermetallic compound combining iridium and gold in a 3:1 ratio, belonging to the family of high-performance metallic alloys. This material is primarily studied in research and specialized industrial contexts where extreme corrosion resistance, chemical inertness, and thermal stability are critical; it finds application in catalysis, electrochemistry, and high-reliability electronic contacts where the combined noble metal properties justify the material cost. Engineers select Ir₃Au over simpler gold or iridium alloys when superior durability under harsh chemical or electrochemical environments is needed, particularly in systems where contamination or material dissolution cannot be tolerated.
