WS
metal· JVASP-36045· WS
WS is a dense metallic material, likely a tungsten-based alloy or composite given its high density and designation. Without complete compositional data, this appears to be either a tungsten-heavy alloy (possibly tungsten-nickel-iron or similar) commonly used in applications requiring exceptional density and radiation shielding, or potentially a research-phase material. Tungsten-base systems are valued in aerospace, defense, and medical imaging for their combination of high density, thermal stability, and radiation absorption properties, offering advantages over lead in shielding applications due to superior strength and lower toxicity concerns.

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.
