· JVASP-116482· Sc3Cu4Si4

Sc3Cu4Si4 is an intermetallic compound combining scandium, copper, and silicon—a ternary metal system that belongs to the family of advanced intermetallics and represents an emerging research composition rather than an established commercial alloy. This material class is of interest to researchers investigating novel strengthening mechanisms and phase stability in lightweight multi-component metal systems, with potential relevance to high-performance structural applications where scandium's rare-earth strengthening effects and copper's thermal/electrical properties can be leveraged. The copper-silicon combination also suggests possible applications in thermal management or electronic packaging if suitable processing routes can be developed, though Sc3Cu4Si4 itself remains primarily a laboratory compound without widespread industrial deployment.

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.
