· JVASP-68159· BeOsW2

BeOsW2 is a refractory metal composite combining beryllium oxide with osmium and tungsten, designed for extreme-temperature and high-density applications. This material belongs to the family of advanced refractory composites and represents specialized research-phase development rather than established commercial production. Its exceptional density and thermal stability make it a candidate for specialized aerospace, nuclear, or high-energy physics applications where conventional metals become inadequate.

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.
