Bi5W
metal· JVASP-123862· Bi5W
Bi5W is an intermetallic compound composed primarily of bismuth and tungsten, belonging to the family of refractory metal-bismuth systems. This material is primarily of research and specialized industrial interest, valued for applications requiring high density, thermal management in electronics, and potential use in radiation shielding where bismuth's nuclear properties are leveraged with tungsten's refractory characteristics. Compared to conventional lead-based or depleted uranium alternatives, Bi5W offers environmental and regulatory advantages while maintaining effective shielding performance in compact geometries.

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.
