· JVASP-127674· PmW3

PmW3 is a metallic compound in the tungsten-based refractory metal family, likely containing promethium or functioning as a tungsten-rich intermetallic phase. This material belongs to the class of ultra-dense, high-melting-point metals used in extreme-environment applications where thermal stability and density are critical. PmW3 is primarily investigated in research contexts for high-temperature aerospace components, radiation shielding, and advanced nuclear or space propulsion systems, where its exceptional density and refractory properties offer advantages over conventional 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.
