· JVASP-14930· BW

BW is a dense metallic material, likely a tungsten-based alloy or composite given its high density and elastic properties. It is used in applications requiring exceptional hardness, wear resistance, and dimensional stability at elevated temperatures. Common industrial applications include tooling, wear components, and radiation shielding, where its combination of stiffness and density provides advantages over lighter alternatives in demanding environments.

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.
