· JVASP-67785· YBeNb4

YBeNb4 is an intermetallic compound composed of yttrium, beryllium, and niobium. This is a research-phase material rather than a production alloy; compounds in this family are investigated for their potential to combine the lightweight and stiffness properties of beryllium with the high-temperature strength and refractory characteristics of niobium. Such yttrium-containing intermetallics are of interest in aerospace and high-temperature applications where weight, thermal stability, and mechanical performance at elevated temperatures must be balanced, though commercial viability and manufacturing scalability remain under evaluation.

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.
