· JVASP-99569· NiIr3

NiIr3 is an intermetallic compound composed of nickel and iridium, belonging to the family of refractory metal alloys known for exceptional hardness and thermal stability. This material is primarily of research and specialized industrial interest, where its extreme density and stiffness make it valuable for high-performance applications requiring both mechanical strength and resistance to extreme environments. The nickel-iridium system is explored for aerospace, catalytic, and wear-resistant applications where conventional superalloys reach their thermal or mechanical limits.

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.
