· JVASP-111795· Nb3V5B8Ir4

Nb3V5B8Ir4 is a complex refractory metal alloy combining niobium, vanadium, boron, and iridium—a composition that places it in the family of high-performance intermetallic and ceramic-reinforced metallic systems. This material is primarily of research or specialized aerospace interest, designed to achieve exceptional high-temperature strength and oxidation resistance by leveraging the refractory properties of niobium and vanadium combined with the hardening and thermal stability contributions of boron and iridium. Engineers would consider this material for extreme environments where conventional superalloys reach their thermal or mechanical limits, though its development status, manufacturability, and cost suggest evaluation within directed aerospace, defense, or ultra-high-temperature applications rather than broad industrial use.

Export Control

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.
