AlIr
metal· AlIr
AlIr is an intermetallic compound combining aluminum and iridium, representing a high-performance metallic material system from the platinum-group-metal alloy family. This material is primarily of research and specialized industrial interest, valued for applications requiring exceptional stiffness, thermal stability, and corrosion resistance where the cost of iridium can be justified. AlIr is used selectively in aerospace, high-temperature catalysis, and precision instrumentation where conventional aluminum alloys or even nickel superalloys prove insufficient.

Regulatory Screening
Environmental
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.
