· JVASP-127685· W3S

W3S is a tungsten-based heavy metal alloy designed for applications requiring extreme density and high-temperature stability. It is primarily used in aerospace, defense, and radiation shielding applications where its exceptional density provides superior performance in weight-constrained or high-energy environments. The alloy is notable for combining tungsten's inherent hardness and melting point with controlled alloying elements to improve machinability and workability compared to pure tungsten.

Regulatory Screening

Environmental

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.
