· Mg2 Al4 Cu2

Mg₂Al₄Cu₂ is an intermetallic compound combining magnesium, aluminum, and copper—a ternary phase that belongs to the magnesium-aluminum-copper system. This material is primarily of research interest for lightweight structural applications where the combination of low density (from Mg and Al) and enhanced mechanical properties (from Cu alloying) could offer advantages over conventional binary Mg-Al alloys. Industrial use remains limited; the compound is studied for potential aerospace and automotive applications where weight reduction and specific strength are critical, though processing challenges and brittleness typical of intermetallics have hindered widespread adoption.

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.
