· JVASP-106628· Zn3Au

Zn₃Au is an intermetallic compound combining zinc and gold in a 3:1 stoichiometric ratio, belonging to the family of precious-metal intermetallics. This material is primarily of research and specialized industrial interest rather than widespread commercial use, with applications emerging in electronics, wear-resistant coatings, and high-reliability joining systems where gold's corrosion resistance combines with zinc's economy and processing advantages.

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.
