· JVASP-90547· MgAl3

MgAl3 is an intermetallic compound in the magnesium-aluminum system, representing a stoichiometric phase that combines the lightweight benefits of magnesium with aluminum's strength and castability. While primarily of research and metallurgical interest rather than a standalone commercial alloy, this phase appears in cast magnesium-aluminum alloys where it forms as a secondary constituent, influencing mechanical properties, corrosion resistance, and elevated-temperature performance. Engineers encounter MgAl3 indirectly when specifying cast Mg-Al alloys for weight-critical applications, as the presence and morphology of this intermetallic phase significantly affects damping capacity, creep resistance, and failure modes.

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.
