· Sc2 Ir1 Ru1

Sc₂Ir₁Ru₁ is an experimental ternary intermetallic compound combining scandium with the platinum-group metals iridium and ruthenium. This material belongs to the class of high-entropy or multi-principal-element intermetallics, which are primarily under investigation in materials research rather than established in production applications. The combination of scandium's lightweight character with iridium and ruthenium's exceptional corrosion resistance, thermal stability, and catalytic properties makes this compound potentially valuable for advanced aerospace, chemical processing, or catalytic applications where extreme conditions and chemical durability are required.

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.
