· JVASP-128827· As5Au

As₅Au is an intermetallic compound combining arsenic and gold, belonging to the family of precious metal alloys. This material is primarily of research and specialized industrial interest rather than a mainstream engineering material, with applications centered on high-reliability electronic contacts, specialized thin-film coatings, and materials science investigations into metal-metalloid phase behavior. Engineers would consider this alloy in niche scenarios requiring the corrosion resistance of gold combined with the unique electronic or mechanical properties that arsenic incorporation provides, though availability and cost typically limit its use to critical applications where standard alternatives prove insufficient.

Export Control

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.
