· Sc2 Al1 Ru1

Sc2Al1Ru1 is an intermetallic compound combining scandium, aluminum, and ruthenium—a research-phase material studied for potential high-performance structural and functional applications. This ternary system represents an experimental composition within the broader family of refractory intermetallics, where the addition of ruthenium (a precious transition metal) to scandium-aluminum phases aims to enhance mechanical robustness and thermal stability compared to binary scandium-aluminum compounds. The material remains primarily in academic and developmental investigation rather than established industrial production, making it relevant for engineers evaluating next-generation aerospace, high-temperature, or specialty electronic device concepts where unconventional alloying strategies may unlock performance advantages.

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.
