· Au2

Au2 is a gold-based intermetallic compound classified as a semiconductor, representing a distinct phase in the gold alloy system with potential electronic and structural applications. This material belongs to the family of metallic intermetallics and is primarily of research and developmental interest rather than established in high-volume industrial production. Au2 systems are investigated for specialized applications where the combination of gold's chemical inertness and nobility with semiconducting properties could enable novel device functionality, particularly in high-reliability electronics and sensor systems where traditional semiconductors face limitations.

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.
