· JVASP-65151· BeNb4W

BeNb4W is a beryllium-niobium-tungsten intermetallic compound that belongs to the refractory metal alloy family, combining the lightweight and high-stiffness characteristics of beryllium with the high-temperature strength and refractory properties of niobium and tungsten. This material is primarily of research and development interest rather than mainstream industrial production, with potential applications in aerospace and high-temperature structural applications where extreme weight savings and thermal resistance are critical. The combination of beryllium's low density with the refractory metals' temperature stability makes it a candidate for advanced aerospace propulsion systems and space structures, though processing challenges and beryllium toxicity concerns limit its current adoption compared to more conventional superalloys and composite alternatives.

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.
