· JVASP-35961· B12W

B12W is a tungsten-based metal alloy, likely a composite or intermetallic compound incorporating boron and tungsten as primary constituents. This material family is typically explored for high-temperature structural applications and wear-resistant components where the hardness of tungsten and boron compounds provides significant performance advantages over conventional steels and aluminum alloys.

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.
