PPbW
metal· JVASP-78700· PPbW
PPbW is a lead-based alloy combining lead with tungsten, belonging to the class of high-density metal systems. This material is engineered for applications requiring exceptional mass concentration in compact geometries, leveraging lead's high density and tungsten's strength and thermal stability to create a composite with superior performance compared to lead alone or alternative high-density metals.

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.
