· JVASP-139845· Hf10SiMo3

Hf10SiMo3 is a refractory metal alloy based on hafnium with silicon and molybdenum additions, designed to retain strength and oxidation resistance at extreme temperatures. This material belongs to the family of ultra-high-temperature ceramics and refractory metals, developed primarily for aerospace and advanced propulsion applications where conventional superalloys reach their performance limits. The hafnium-silicon-molybdenum system is notable for maintaining structural integrity in hypersonic flight environments and rocket propulsion systems, where it competes with other refractory compounds like hafnium carbides and molybdenum silicides.

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.
