· Al4(NiIr)3

Al₄(NiIr)₃ is an intermetallic compound combining aluminum with nickel and iridium, forming a complex ordered crystal structure in the metal alloy family. This material belongs to the family of high-performance intermetallics studied for elevated-temperature applications where conventional superalloys or aluminum alloys reach their performance limits. As a research-stage material, Al₄(NiIr)₃ is investigated primarily for its potential combination of low density (from the aluminum base) with high-temperature strength and oxidation resistance (from the noble metal and nickel constituents), though industrial deployment remains limited compared to established superalloy systems.

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.
