· JVASP-61944· GaAu2

GaAu₂ is an intermetallic compound formed between gallium and gold, belonging to the family of precious metal intermetallics. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, with applications emerging in microelectronics, optoelectronics, and high-reliability contact systems where the combination of gold's corrosion resistance and gallium's semiconductor properties offers advantages in extreme environments or demanding electrical performance.

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.
