· Sc1 Al1 Ir2

ScAlIr₂ is an experimental intermetallic compound combining scandium, aluminum, and iridium in a 1:1:2 stoichiometric ratio. This material belongs to the family of lightweight refractory intermetallics and is primarily of research interest rather than established industrial production. The combination of scandium and aluminum provides potential for low density, while iridium contributes high melting point and corrosion resistance, making this compound potentially relevant for extreme-environment aerospace and high-temperature structural applications where conventional superalloys face performance limitations.

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.
