· JVASP-71578· Y2BeW

Y2BeW is a beryllium-tungsten intermetallic compound that combines the lightweight characteristics of beryllium with tungsten's high density and refractory properties. This material exists primarily in research and specialized aerospace/defense contexts, where its unique combination of low density with high stiffness and thermal stability is explored for applications demanding extreme performance under demanding conditions. Engineers would consider Y2BeW only for advanced developmental programs where beryllium's toxicity concerns and manufacturing complexity are outweighed by performance gains unavailable from conventional titanium or nickel-based alloys.

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.
