· JVASP-107316· MgSc5Al4

MgSc5Al4 is a magnesium-scandium-aluminum ternary intermetallic compound, representing an experimental material system combining lightweight magnesium with scandium and aluminum additions to enhance mechanical properties and thermal stability. While not yet established in mainstream industrial production, this alloy composition is of research interest for applications requiring very low density combined with improved strength and creep resistance compared to conventional magnesium alloys. Engineers would consider this material family primarily in early-stage development projects where weight reduction is critical and cost constraints allow for specialized alloy development.

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.
