· CuAuSe4

CuAuSe₄ is a quaternary compound combining copper, gold, and selenium in a metallic system, representing an experimental material from the family of precious-metal selenides. This compound has been studied primarily in materials research contexts for its potential electronic and structural properties, though it remains outside mainstream industrial production. Its notable density and elastic characteristics suggest possible applications in niche electronics or thermoelectric research, though practical engineering use cases are limited and the material remains largely in the exploratory phase.
