· JVASP-106691· ZnCu3

ZnCu3 is a zinc-copper intermetallic compound representing a stoichiometric phase in the Cu-Zn system. This material is primarily of research and metallurgical interest, appearing in brass alloys and copper-zinc phase diagrams as a distinct crystalline phase rather than as a commercially produced standalone material. Its applications are largely indirect—occurring as a microstructural constituent in multi-phase brass alloys used for electrical contacts, decorative components, and corrosion-resistant applications where its presence influences overall mechanical and electrical behavior.

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.
