Cu1 Zn2 Au1
semiconductor· Cu1 Zn2 Au1
Cu₁Zn₂Au₁ is an experimental ternary intermetallic compound combining copper, zinc, and gold in a defined stoichiometric ratio. This material belongs to the family of noble metal-bearing intermetallics, which are of research interest for applications requiring corrosion resistance, wear resistance, and electrical properties beyond conventional brasses or bronzes. Limited industrial deployment exists; the compound is primarily studied in materials research contexts for high-reliability electronic contacts, specialty jewelry alloys, and corrosion-resistant coatings where the gold content provides nobility and the zinc-copper matrix offers structural stability.
