· B2 W2

B2 W2 is a tungsten-based intermetallic compound with a body-centered cubic (B2) crystal structure, representing a class of high-temperature refractory materials studied primarily in materials research contexts. While not yet established as a mainstream commercial alloy, B2-structured intermetallics—particularly tungsten-containing variants—are investigated for extreme-temperature structural applications where conventional superalloys reach their limits, including aerospace propulsion, nuclear reactor components, and high-temperature wear surfaces.

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.
