· JVASP-42859· ScAlIr2

ScAlIr2 is a ternary intermetallic compound combining scandium, aluminum, and iridium, representing an experimental high-performance alloy in the refractory metal family. This material is primarily of research interest rather than established industrial production, investigated for applications requiring exceptional stiffness and thermal stability at elevated temperatures where conventional alloys degrade. The incorporation of iridium—a platinum-group metal—and scandium enables potential use in extreme-environment aerospace and energy systems, though engineering adoption remains limited pending scale-up, cost reduction, and validation of manufacturing feasibility.

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.
