· JVASP-65077· Mg4MnBe

Mg4MnBe is a quaternary magnesium alloy containing manganese and beryllium additions, belonging to the family of lightweight metallic materials based on magnesium. This composition represents a research or specialized alloy formulation designed to explore property combinations from beryllium strengthening and manganese refinement effects, though it remains relatively uncommon in mainstream industrial production. The material would appeal to engineers in aerospace and defense sectors seeking reduced-density alternatives where magnesium's inherent lightness is leveraged, though the presence of beryllium (a toxic powder hazard) restricts its use to applications where manufacturing and handling can be carefully controlled and where cost and toxicity concerns are acceptable tradeoffs for performance gains.

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.
