· JVASP-126442· Pb3W

Pb3W is an intermetallic compound composed of lead and tungsten, representing a heavy metal phase that forms under specific compositional and thermal conditions. This material belongs to the lead-tungsten binary system and is primarily of research and metallurgical interest rather than widespread industrial production. Applications are limited and typically experimental, focusing on specialized studies of phase diagrams, high-density materials, and potential use in radiation shielding or specialized alloy development where the combination of lead's density and tungsten's refractory properties may offer advantages over single-element 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.
