metal

· BW2

BW2 is a tungsten-based heavy metal alloy, likely containing tungsten as the primary constituent with secondary alloying elements to enhance workability and performance. The material is valued in applications requiring extreme density, high stiffness, and radiation shielding properties, making it particularly suited to aerospace, defense, and medical imaging sectors where weight efficiency and material performance under demanding conditions are critical.

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.
