· JVASP-104603· Nb2ReRu

Nb₂ReRu is a high-entropy refractory metal alloy combining niobium, rhenium, and ruthenium—three elements with exceptionally high melting points. This material exists primarily in the research domain as an experimental composition being studied for extreme-temperature and high-stress applications where conventional superalloys reach their performance limits. The ternary system is of particular interest for aerospace and power generation sectors seeking next-generation materials that maintain strength and oxidation resistance at temperatures beyond the capability of nickel-based superalloys.

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.
