B2Au
metal· JVASP-4708· B2Au
B2Au is an intermetallic compound with a B2 (CsCl-type) crystal structure, composed of gold and another element in a 1:1 atomic ratio. This material belongs to the family of ordered intermetallics, which are candidates for high-temperature and structural applications due to their ordered atomic arrangement and potential for enhanced mechanical properties. B2Au remains primarily a research material; its development targets applications requiring the combination of gold's chemical stability with intermetallic hardness and stiffness, though practical engineering use is limited by cost and processing challenges inherent to gold-based compounds.

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.
