· JVASP-145246· YCo9Si4

YCo9Si4 is an intermetallic compound combining yttrium, cobalt, and silicon, belonging to the rare-earth transition metal silicide family. This material is primarily of research interest for high-temperature structural applications and magnetic device development, where the combination of rare-earth and transition metal constituents offers potential for enhanced mechanical properties and functional magnetic behavior at elevated temperatures. Its use remains largely experimental, with potential applications in aerospace thermal management systems and advanced permanent magnet technologies where conventional alloys reach their performance limits.

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.
