· JVASP-79127· Al3Zn

Al₃Zn is an intermetallic compound consisting of aluminum and zinc in a 3:1 stoichiometric ratio, representing a distinct phase that forms within the Al-Zn binary system. This material is primarily encountered as a constituent phase in aluminum-zinc alloys rather than as a standalone engineering material, where it contributes to precipitation hardening and age-hardening mechanisms in commercial alloys like 7xxx-series aluminum. Al₃Zn's significance lies in its role in controlling mechanical properties through microstructural engineering; understanding its formation and dissolution kinetics is critical for heat-treatment optimization of high-strength aerospace and automotive components.

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.
