· JVASP-140398· Nb5CrB4Ru10

Nb5CrB4Ru10 is a complex refractory metal alloy combining niobium, chromium, boron, and ruthenium—a research-phase compound designed to achieve high-temperature strength and oxidation resistance. This material belongs to the family of advanced refractory alloys and represents experimental work toward extreme-environment structural materials, with potential applications where conventional superalloys reach their thermal limits. The ruthenium content and boron reinforcement strategy distinguish it from commercial refractory systems, though the composition and processing pathways suggest active development rather than established production.

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.
