· InAu3

InAu₃ is an intermetallic compound formed between indium and gold, belonging to the family of precious metal alloys. This material is primarily of research and specialized industrial interest, valued for applications requiring the combined properties of gold's corrosion resistance and chemical inertness with indium's semiconductor and thermal characteristics. InAu₃ appears in thin-film electronics, bonding applications, and experimental systems where the interaction between these two elements offers advantages over single-metal alternatives, though it remains less common than binary gold alloys in mainstream engineering.

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.
