· JVASP-129198· 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.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
