WBr6
metal· WBr6
WBr₆ (tungsten hexabromide) is a halogenated tungsten compound that exists primarily as a research material rather than a commercial engineering metal. It belongs to the family of tungsten halides, which are of interest in materials science for chemical vapor deposition (CVD) processes and synthesis of tungsten-containing coatings and composites. While not widely deployed in structural applications, tungsten halides serve niche roles in semiconductor processing, refractory coating development, and advanced materials research where tungsten's high melting point and chemical stability are leveraged.

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.
