· B5W2

B5W2 is a tungsten-based heavy metal alloy, likely a tungsten-rhenium or tungsten-molybdenum composition used where high density and refractory properties are critical. This material is employed in applications requiring excellent thermal stability, radiation shielding, or ballistic performance, where its exceptional density provides superior protection or performance in compact geometries compared to conventional steels or lead-based alternatives.

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.
