· JVASP-111009· Si4MoW

Si₄MoW is a refractory metal silicide alloy combining silicon, molybdenum, and tungsten, designed for extreme-temperature and wear-resistant applications. This material belongs to the family of transition-metal silicides, which are studied for high-temperature structural use where conventional superalloys reach their limits. The tungsten and molybdenum additions enhance hardness and creep resistance, making it a candidate for aerospace propulsion, industrial furnace components, and wear-intensive environments where oxidation and thermal cycling are primary failure modes.

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.
