Mg3Nb
metal· JVASP-79163· Mg3Nb
Mg3Nb is an intermetallic compound composed of magnesium and niobium, representing a research-phase material in the magnesium-refractory metal family. This compound is primarily investigated for lightweight structural applications where thermal stability and high-temperature performance are critical, as niobium addition significantly improves the thermal creep resistance of magnesium-based systems compared to conventional Mg alloys. While not yet widely commercialized, Mg3Nb and related magnesium-niobium intermetallics show promise in aerospace and automotive contexts where reducing mass while maintaining strength at elevated temperatures could provide substantial fuel efficiency 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.
