Sc2AlIr
metal· JVASP-39109· Sc2AlIr
Sc2AlIr is an intermetallic compound combining scandium, aluminum, and iridium, belonging to the class of high-performance metallic materials designed for extreme environments. This material is primarily of research and development interest rather than established production use, with potential applications in aerospace and high-temperature engineering where combinations of strength, stiffness, and thermal stability are critical. The inclusion of iridium—a precious refractory metal—makes this alloy notable for specialized applications where conventional superalloys or titanium alloys reach their performance limits, though cost and manufacturability remain significant considerations relative to alternatives.

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.
