· JVASP-129477· InAu

InAu is an intermetallic compound formed from indium and gold, belonging to the precious metal alloy family. It is primarily investigated in microelectronics and materials research for its potential in semiconductor bonding, contact metallurgy, and high-reliability interconnection systems where the combination of indium's softness and gold's stability offers advantages in thermal and electrical performance. This material remains largely in the research and development phase rather than widespread production use, with interest driven by demands for improved bump bonding in flip-chip assemblies and hybrid integrated circuits where conventional solders face thermal cycling challenges.

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.
