Al5Ni4Ir
metal· Al5Ni4Ir
Al5Ni4Ir is an intermetallic compound combining aluminum, nickel, and iridium—a research-phase material designed to achieve high-temperature strength and oxidation resistance by leveraging iridium's exceptional thermal stability. This ternary alloy targets applications where conventional superalloys face limitations, particularly in extreme-temperature environments where both lightweight aluminum benefit and iridium's refractory properties are valued; however, it remains largely experimental and would be selected only when superior high-temperature performance justifies the material and processing costs relative to established alternatives like Ni-based superalloys or tungsten-based composites.

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.
