· JVASP-41257· HfMgIr2

HfMgIr2 is an intermetallic ceramic compound combining hafnium, magnesium, and iridium—a research-phase material designed to exploit the high melting point and refractory properties of hafnium-iridium systems while potentially benefiting from magnesium's lower density contribution. This material belongs to the family of high-entropy and complex intermetallics under investigation for extreme-temperature structural applications where conventional superalloys reach their limits. While not yet in widespread commercial production, HfMgIr2 represents the broader push toward ultra-refractory ceramics and intermetallics for aerospace propulsion, advanced energy systems, and next-generation thermal-barrier components where oxidation resistance and mechanical stability at very high temperatures are critical.

Regulatory Screening

Environmental

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.
