VW
metal· JVASP-123002· VW
VW is a dense metallic material with high stiffness and moderate damping characteristics, likely a tungsten-based or tungsten-containing alloy given its high density and elastic properties. This material family is valued in aerospace, defense, and precision engineering sectors where weight-critical applications demand exceptional strength-to-stiffness ratios and vibration damping. Engineers select tungsten alloys when thermal stability, radiation shielding, or inertial mass concentration in compact geometries is critical, though cost and machinability trade-offs versus steel or aluminum alternatives must be evaluated.

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.
