· JVASP-108914· ZnAu4

ZnAu4 is an intermetallic compound composed of zinc and gold in a 1:4 atomic ratio, belonging to the family of gold-based intermetallics. This material is primarily encountered in jewelry metallurgy, dental applications, and electronics interconnection, where its high density and gold content provide corrosion resistance and aesthetic properties. ZnAu4 is notable for its use in specialized brazing alloys and as a constituent phase in gold-zinc master alloys, though it remains less common than simpler binary gold alloys due to its brittle intermetallic nature and processing complexity.

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.
