· JVASP-91887· Mg7Ni

Mg7Ni is an intermetallic compound in the magnesium-nickel system, forming a hard, brittle phase that typically appears as a secondary constituent in magnesium alloys rather than as a standalone engineering material. This compound has attracted research interest primarily in hydrogen storage applications and as a reinforcing phase in magnesium composites, where its high hardness can improve wear resistance and strength at elevated temperatures. Mg7Ni is notable in the hydrogen storage community because nickel-containing magnesium phases can catalyze hydrogen absorption and desorption, making them relevant for advanced energy storage research, though commercial adoption remains limited compared to competing hydrogen storage media.

Export Control

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.
