PW3
metal· JVASP-133176· PW3
PW3 is a tungsten-based heavy metal alloy, likely containing tungsten as the primary constituent with secondary alloying elements to enhance mechanical properties and workability. The material is notable for its extremely high density and strength-to-weight characteristics, making it valuable in applications where mass concentration and ballistic or radiation-shielding performance are critical design factors. Engineers select PW3 over alternatives like lead or depleted uranium when non-toxic, high-performance alternatives are required or when superior mechanical properties at extreme density are necessary.

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.
