· JVASP-117139· Nb3B2Ru5

Nb3B2Ru5 is an intermetallic compound combining niobium, boron, and ruthenium—a research-stage material belonging to the refractory metal boride family. This composition is primarily investigated for ultra-high-temperature structural applications where conventional superalloys reach their thermal limits, leveraging ruthenium's oxidation resistance and niobium's strength alongside boron's hardening effects. The material remains largely experimental; its relevance lies in advancing next-generation aerospace and power generation systems rather than current commercial 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.
