· Si2Mo

Si2Mo is an intermetallic compound combining silicon and molybdenum, belonging to the refractory metal silicide family. This material exhibits high stiffness and moderate density, making it relevant for high-temperature structural applications where conventional metals lose strength. Si2Mo is primarily investigated in research contexts for aerospace and automotive powertrains, where its refractory nature and elastic properties suit extreme thermal environments, though industrial adoption remains limited compared to established superalloys and ceramic composites.

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.
