· JVASP-35657· In2Au3

In₂Au₃ is an intermetallic compound formed between indium and gold, belonging to the family of precious metal intermetallics. This material is primarily of research and specialized industrial interest rather than a high-volume engineering material, with applications in microelectronics, thin-film technologies, and contact metallurgy where the combination of gold's conductivity and corrosion resistance with indium's properties offers specific performance advantages in extreme miniaturization or reliability-critical contexts.

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.
